6 This is how your heat pump works FOR THE USER This is how your heat pump works The heat pump collects stored solar energy The heat pump Greenline HT Plus represents a new generation of heat pumps from IVT Industrier. The heat pump has been manufactured for easy and reliable use as well as to provide your house with inexpensive and environment friendly heating.

The easiest way to describe how a heat pump works is to say it works like a refrigerator, however, the other way round. In a refrigerator, heat is moved from the inside to the outside. In a heat pump, heat stored in the ground, rock or water, is moved into the house.

The heat pump collects a few degrees of the stored solar energy. The heat is led into the house via a hose. The temperature is then increased in the heat pump and the heat is distributed to the house s heating system. Rock heat Soil heat Lake heat Technology in and around the heat pump The heat pump consists of four main parts: 1.

Evaporator Evaporates the refrigerant to gas and at the same time transfers the heat from the heat transfer fluid to the refrigerant circuit. Condenser Condenses the gas to fluid again and transfers the heat to the heating system. Expansion valve Lowers the pressure of the refrigerant. Compressor Increases the pressure of the refrigerant. These four main parts are linked in three circuits.

A refrigerant circulates in the heat pump, which in some parts of the circuit is in a liquid state and in other parts in a gas state. Read more about the properties of the refrigerant in the sidebar to the right. Boiling point in relation to the pressure: The boiling point of different liquids varies with pressure, the higher the pressure, the higher the boiling point. For example, water boils at +100ºC at normal pressure.

Double the pressure and water boils at +120ºC. Half the pressure and water then boils at +80ºC. The refrigerant in the heat pump acts in the same way, the boiling point changes when the pressure changes. However, the boiling point of the refrigerant is as low as approximately -40ºC at atmospheric pressure. Consequently, it is also suitable for low heat source temperatures. See the detailed description of the technologies used in the heat pump on the next page.

7 This is how your heat pump works The cold side The hot side 1 6 Heat transfer pump 0ºC -3ºC ºC +100ºC Floor heating FOR THE USER Soil -10ºC 5 Heat carrier pump Radiator Rock Heat pump Fan-assisted radiator Heat transfer fluid in. A hose is connected here that collects the stored solar energy from, e.g., the soil or rock. The hose contains a heat transfer fluid, which is a mixture of water and anti-freeze. The fluid collects the heat from the rock and with the help of the HTF pump leads it into the heat pump and the evaporator. The temperature is then approximately 0ºC.

In the evaporator, the heat transfer fluid meets the refrigerant. At this stage, the refrigerant is in a fluid state and is at approximately -10ºC. When the refrigerant meets the zero degree heat transfer fluid it starts to boil. It then forms a vapour, which is led into the compressor. The temperature of the vapour is 0ºC. The pressure of the refrigerant increases in the compressor and the vapour temperature rises from 0ºC to approximately +100ºC.

The warm gas is then forced into the condenser. 4 5 The condenser is the heat pump s heat emitting part. Here the heat is transferred to the house s heating system (radiators and floor heating) and the hot water system. The vapour is cooled in the condenser and becomes fluid. The pressure in the refrigerant is still high when it is led on to the expansion valve. The refrigerant pressure is lowered in the expansion valve.

At the same time, the temperature also drops to approximately -10ºC. When the refrigerant has passed through the valve and the evaporator it changes to vapour again.

6 In heat transfer fluid out, the heat transfer fluid is led out from the heat pump to the rock to collect new stored solar energy. The temperature of the fluid is approximately -3ºC. 8 Component parts of the heat pump FOR THE USER Component parts of the heat pump IVT Greenline HT Plus C Three-way valve The valve switches between heating the heating water and hot water.

It makes sure the heat pump gives the best energy savings and that it runs for many years.

The control unit controls and monitors the heating and hot water supply in your house. The monitoring function is especially important.

It shuts down the heat pump in the event of operational disturbances so that no critical parts are damaged. Additional heat gives more output When the heat pump can not manage to heat the house by itself, for example, if there is a considerable drop in the outdoor temperature, the control unit ensures the additional heat source is connected. Together the heat pump and additional heat guarantee the right temperature in the house. Additional heat in the Greenline HT Plus is provided by a built in electric cassette.

Additional heat can never completely take over the heating from the heat pump. It only adds the output necessary for the heat pump to be able to produce the right temperature. When the heat pump can once again manage heating on its own the additional heat is automatically disconnected. Three-way valve Electric cassette (additional heat) Control unit Hot water is given priority over heating water In a house with water based heating a difference is made between heating water and hot water.

The heating water is for radiators/floor heating and hot water is for showers and taps. Hot water is heated in a hot water heater. The hot water heater is fitted with a sensor that senses the temperature of the hot water. C models include a hot water heater in the heat pump while E models have an external hot water heater. The heating water passes through the hot water cylinder s outer shell and heats up the hot water heater s inner tank.

The control unit makes sure the heating of hot water is always given priority over the heating of the heating water. This means you never need to be without hot water. The control unit controls a three-way valve that switches between heating the heating water and hot water. Once the hot water has been heated the three-way valve switches so that the heating water is heated. Hot water Heating water Double-shelled hot water cylinder 10 11 Control unit Rego 637 The control unit s two methods to control the heat pump The control unit uses two different methods to control the heat pump. These two methods are: Control with an outdoor sensor and Control with an outdoor sensor supplemented with a room sensor.

Control with outdoor sensor Control with an outdoor sensor is the most common method used by the control unit to control the heat pump. When the heat pump is delivered it is set for this control method. A sensor is fitted on the outside wall of the house. It sends signals to the control unit in the heat pump. Control with an outdoor sensor means that the heat pump automatically regulates the heating in the house depending on the outdoor temperature. If the outdoor temperature drops, i.e.

It becomes colder; the radiators inside the house will become warmer. FOR THE USER You determine the temperature of the radiators, in relation to the outdoor temperature, with the help of a number of settings such as selecting the heat curve on the control unit. A lower curve gives higher energy savings.

Control with an outdoor sensor supplemented with room sensor Control with an outdoor sensor supplemented with a room sensor means that you also place a sensor in a central position inside the house. This is connected to the heat pump and provides the control unit with information about the room temperature.

The signals affect the control unit s settings (curves) and ensure the heat pump gives the best possible energy savings. It is only the room where the room sensor is located that can influence regulation of the temperature. This control method is used when factors other than the outdoor temperature influence the indoor temperature. Examples include the use of a stove or fan-assisted radiator or if the house is sensitive to the wind. 12 Control panel FOR THE USER Control panel All settings are made from the control panel. It also displays heat production statistics and information about different alarms.

When you have made your settings, the control panel makes sure they are saved in the control unit Rego 637 to carry out your wishes. Controls and status lamps Control panel Power switch (ON/OFF) You start and stop the heat pump using the power switch button. Lamp on: The heat pump is on. Lamp flashes: The heat pump is off.

HEAT RAD REQ Heat pump starts in 320 seconds Return to the initial menu by pressing one of the buttons or turn the dial. Set the heating It is easy to set the heating level on the heat pump. However, before we explain how to do this it is important to understand the relation between the outdoor temperature, return temperature and heat curve slope.

The easiest way to explain the relation is with a heat curve. Heat curve You use the heat curve to help set the indoor temperature you would like. The heat pump is controlled by the outdoor temperature. When the weather becomes colder, the heat pump ensures more heating is produced automatically.

Return temperature: The return temperature is the temperature of the water that returns to the heat pump from the radiators. The water led out from the heat pump to the heating system is normally 7-10ºC higher than the return temperature. When the outdoor temperature is -10ºC and curve 4 is set, the pump attempts to keep the return water at approximately 40ºC. Outdoor temperature: The outdoor temperature determines how much heating the heat pump should produce. A sensor placed outdoors sends signals to the control unit, which then adjusts the heat pump. Curve slope: You can change the curve slope to increase or decrease the heating in the house.

The scale is between On delivery the heat pump curve slope is set to position 4. This means that the return temperature is +35ºC when it is 0ºC outdoors. 15 16 Basic functions - Customer level 1 FOR THE USER Change the curve slope The heat pump s production of heating is adjusted by increasing or decreasing the curve slope in the Temp.

This is especially effective in cold weather conditions. Return temperature (ºC) Curve slope (0-10) Curve slope: 2-4 Normal setting for floor heating. 4-6,5 Normal setting for radiators Abnormal high setting. Outdoor temperature (ºC) Dashed line: If the return temperature exceeds 57ºC an alarm is given and the compressor switches off. The heat pump starts automatically when the return temperature drops. From the heat curve we see that curve slope 4 gives a return temperature of +35ºC when it is 0ºC outdoors.

If the outdoor temperature drops we can see that the return temperature increases. The colder the outdoor temperature the higher the return temperature.

At an outdoor temperature of approximately -30ºC we see the curve slope has nearly reached the limit value (+57ºC) for the return temperature. In cold weather (below -5ºC): If you are not satisfied with the indoor temperature when it is colder than +5ºC outdoors, you need to change the slope of the heat curve.

This is what to do: 1. Press the Heat button in the initial menu. 0 4,0 10 Return Adjust 2. Press the Adjust button. Turn the menu dial clockwise to increase the heating.

Turn the menu dial anti-clockwise to lower the heating. (Adjust in small increments, units, is usually enough.) Temp. 0 5,0 10 Return Adjust 4. Save the new value by pressing the Save button. You should wait at least two days when increasing or decreasing the heating before making a new adjustment.

If it is still difficult to get a comfortable indoor temperature at an outdoor temperature around 0ºC, despite several attempts, you should adapt the heat curve. Read about how to adapt the curve in the section Extra functions Customer level 2 / Temperature settings / Adapting the heat curve. 16 17 Basic functions - Customer level 1 Fine-tune the heat cur ve The heat curve can also be fine-tuned. Fine-tuning means that you offset the heat curve in parallel. Fine-tuning is done from the Temp. Fine-tune menu.

The diagram for fine-tuning shows how the dashed line has been offset upwards in parallel. This means the heating has been fine-tuned in a positive direction and the heat pump will be instructed to maintain a higher temperature on the return water at all outdoor temperatures. FOR THE USER Return temperature (ºC) By using the menu dial on the control panel the fine-tuning line has been moved up so the heat pump produces more heat. Outdoor temperature (ºC) In warm weather (above +5ºC): If you are not satisfied with the indoor temperature when it is warmer than +5ºC outdoors, you should offset the curve in the Temp.

28 Maintenance FOR THE USER Care Your heat pump requires a minimum of maintenance, however, we still recommend some servicing to get optimal performance from your heat pump. Check the following items a few times during the first year. You should then check them once or twice a year: Sight glass Expansion vessel Particle filter Protective anode (only models with a stainless steel hot water cylinder) Warning For reasons of safety the main power supply must be disconnected before working on the heat pump.

Only an accredited refrigeration company is permitted to work on the refrigerant circuit. Unscrew the front cover On certain models you will need to open the front cover to access some of the maintenance areas, e.g.

The sight glass and particle filter. The front cover is secured at the top by two screws. This is how you remove the front cover from the heat pump: 1. Unscrew the two screws on the top. See the picture.

Tilt the front cover towards you. Lift the front cover up to release the lower edge. Remove the front cover by unscrewing the screws on the top.

Sight glass Sometimes when the heat pump has started you can see the fluid in the refrigerant circuit bubble for a few minutes in the sight glass. This is completely normal. However, if it bubbles continuously you should contact your dealer. Sight glass If the sight glass shows green this means there is no moisture in the system. If it is yellow, there is moisture in the system. If this happens, contact your dealer. Greenline HT Plus E 28.

29 Maintenance Expansion tank A plastic expansion vessel is connected to the heat pump heat transfer circuit (cold side). The level in the vessel should not fall below the minlevel 1/3. If the fluid level is too low, contact your dealer. After discussions with your dealer filling can take place as set out below: The heat pump must be operational all the time while filling.

Remove the cover on the valve on top of tank. Now carefully open the valve (figure 1). Check that the valve is fully open (figure 2). Fill with anti-freeze or water (to 2/3) with the help of a clean watering can or the like (figure 3).

Close the valve and finish by screwing on the cover (figure 4). Level FOR THE USER Figure 1 Figure 2 Figure 3 Figure 4 29. 30 Maintenance FOR THE USER Particle filter The task of a particle filter ( is to ensure no particles or dirt enter the heat exchangers. Over time the filter can become clogged and will need cleaning.

There are particle filters on both the hot and cold sides. To clean the particle filters: 1. Shut down the heat pump using the ON/OFF button.

Close the valve and unscrew the sealing cap. Loosen the circlip holding the screen in the valve. Use the supplied circlip pliers.

Lift out the screen from the valve and wash clean with water. Refit the screen, the circlip and sealing cap. Open the valve and start the heat pump using the ON/OFF button. On the cold side the particle filter is located outside of the heat pump.

It may be concealed by insulation material or a black box. On Greenline HT E Plus the hot side s particle filter is fitted inside the heat pump. On Greenline HT Plus C it is located outside of the heat pump. Particle filter Screen Circlip Sealing cap Greenline HT Plus E Checking the protective anode Only applies to heat pumps with integrated, stainless hot water cylinder. A protective anode is located in the top of the cylinder with the task of preventing corrosion.

The hot water cylinder must be filled with water in order for the anode to work. A lamp, inside the front cover, indicates the anode status. If green, the protective anode is operating and working normally. Red can indicate a fault. When large amounts of hot water are used (e.g.

With a bath) the lamp may show red for a short period without there being a fault. However, if the light is on for more than ten hours this indicates the anode is faulty and you should contact your dealer. If the fault occurs at the weekend, you can wait to the next working day before contacting your dealer. Electronic anode Lamp 30. 31 Savings Savings The heat pump s task is to produce heating for the house as cost-effectively as possible.

You can influence operating costs by your own settings for the heat pump. In addition, you can influence your energy savings by, for instance Lowering the indoor temperature. Opening thermostat valves completely. FOR THE USER Lowering the indoor temperature The lower the indoor temperature the better the heating economy. So make sure you do not set the heat curve too high. Use your heating system in the best possible way by keeping the entire surface of radiators or floor coils warm.

Seal windows and doors, but not too tight. When you air the room, do it quickly and with a cross draught. Opening thermostat valves completely The thermostat valves on radiators and floor coils can have a negative effect on the heating system by slowing the flow and, by doing so, the heat pump must compensate with a higher temperature.

Greenline Ht Plus C Guide Bgsu

If thermostat valves are installed, they should be opened fully, except in bedrooms or other areas, where a lower temperature is required. In these rooms they can be somewhat closed. Lower the heating.

Open the thermostat valves completely. 31 32 What to do if a fault occurs FOR THE USER What to do if a fault occurs The control unit has an advanced monitoring system that gives alarms if anything unforeseen happens in the heat pump. Most alarms are rectified by you the user and there is never any risk that you can damage anything in the heat pump when you reset an alarm.

The soil fi lling around the hose must not contain stones.

If the hose is ploughed down, you must use equipment that guarantees the hose is laid at the right depth. The heat pump and collector hose in general You can connect the collector hose to the heat pump with one or more circuits. In a multi-circuit solution, the collector hoses are connected in parallel as illustrated below. The parallel hoses are connected to two distributors. Each coil should have a shutoff valve and a control valve.

Preparations before connection Preparations before connection In some situations the heat pump may need extra preparations before it is commissioned. Such preparations may be: Moving the heat transfer fl uid pipe for side entry Supplement the heat pump with a ground water system Moving the heat transfer fl.

Preparations before connection Side installation on the right-hand side Proceed as follows to switch the heat transfer fl uid pipes from top installation to side installation on the right: 1. Remove the blanking washers (fi gure 1). Dismantle the sensor and both heat transfer fl uid pipes. The pipes run to the top of the top plate.

Preparations before connection Side installation on the left-hand side Proceed as follows to switch the heat transfer fl uid pipes from top installation to side installation on the left: 1. Switch the heat pump’s right- and left-hand side covers. Preparations before connection Supplementing the heat pump with a Note ground water system The intermediate heat exchange should be connected against the fl ow. If the heat pump is installed for groundwater instead of rock, soil or lake, it In addition, the pipe from the ground- must be supplemented with an intermediate heat exchanger.

Connecting the heat pump to the heating system Ground water system: Electrical connection 1. Connect the ground water pump to the mains (3 x 400 V) via a motor Warning cut-out and a contactor.

The control to the contactor (CK3) uses 230 V, which is taken from the terminals L and N (P3) in the heat pump. Connecting the heat pump to the heating system Connecting to the heating system without a bypass: The heat pump can be connected to the heating system without a bypass, as the circulation in the heat pump and the heating system is managed by the integrated pump G2 (P2). This also means the main pump G1 (P1) is omitted. An absolute prerequisite for the connection is that a minimum fl.
