Technical description Domestic heat pumps

1 Important parameters

1.1

Heat production - calculating

The indoor temperature is adjusted by changing the heat pump’s heat curve, which is the control system’s tool for calculating what the supply temperature should be for water that is sent out in the heating system. The heat curve calculates the supply temperature depending on the outdoor temperature. The lower the outdoor temperature, the higher the supply temperature. In other words, the supply temperature of the water fed to the heating system will increase linearly as the outdoor air temperature falls.

The heat curve will be adjusted in connection with installation. It must be adapted later on, however, to obtain a pleasant indoor temperature in any weather conditions. A correctly set heat curve reduces maintenance and saves energy.

1.2

CURVE

The control computer shows the value for CURVE by means of a graph in the display. The heat curve can be changed by adjusting the

CURVE value. The CURVE value indicates the supply temperature of the water that is wanted to the heating system at an outdoor temperature of 0°C.

In the event of outdoor temperatures below 0°C, a higher setpoint value is calculated and in the event of outdoor temperatures greater than 0°C, a lower setpoint value is calculated.

If the CURVE value is increased, the heat curve will become steeper and if the value is reduced, it will become flatter.

The most energy efficient and cost effective setting is achieved by changing the CURVE value which leads to fewer starts and longer operating times. For a temporary increase or reduction, adjust the ROOM value instead.

1.3

ROOM

If you wish to increase or reduce the indoor temperature, change the ROOM value.

Changing the ROOM value

When changing the ROOM value, the angle of the curve on the system's heat curve does not change, instead the entire heat curve is moved by 3°C for every degree change of the ROOM value. The reason that the curve is adjusted 3°C is that an approximate 3°C increase in supply temperature is usually needed to increase the indoor temperature 1°C.

The relationship of the supply temperature to the outdoor temperature will not be affected. The supply temperature will be increased or reduced by the same number of degrees all along the heat curve. I.E. The entire heat curve rises or drops instead of the curve gradient changing.

This method of adjusting the indoor temperatures can be used for a temporary raise or drop. For long term increases or reductions of the indoor temperature, the heat curve should be adjusted.

1.4

HEAT STOP

The HEAT STOP function automatically stops all production of radiator heat when the outdoor temperature is equal to, or higher than, the value entered for heat stop.

When the heat stop function is activated, the circulation pump will be turned off - except when hot water is being produced. The circulation pump will be "exercised" for one minute per day. The factory set value for activating heat stop is an outdoor temperature of 17°C. If the heat stop function is active, the outdoor temperature must drop 3°C when setting, before the heat stop is de-activated.

1.5

MIN and MAX

The MIN and MAX values are the lowest, respectively highest set point values that are allowed for the supply temperature.

Adjusting the minimum and maximum supply temperatures is particularly important if your home has under floor heating.

If your house has under floor heating and parquet floors, the supply line temperature must not exceed 45°C. Otherwise the floor might get damaged. If you have under floor heating and stone tiles, the MIN value should be 22-25°C, even in summer when no heating is required. This is to achieve a comfortable floor temperature.

If your house has a basement, the MIN value should be adjusted to a suitable temperature for the basement in summer. A condition for maintaining the heat in the basement in the summer is that all radiators have thermostat valves that switch off the heat in the rest of the house. It is extremely important that the heating system and the radiator valves are trimmed correctly. As it is usually the end customers themselves who have to carry out trimming, remember to inform them how to carry it out correctly. Also remember that the value for

HEAT STOP needs adjusting upwards for summer heating.

1.6

TEMPERATURES

The heat pump can display a graph showing the history of the various sensors’ temperatures and you can see how they have changed over 60 measurement points in time. The time interval between the measurement points can be adjusted between one minute and one hour, factory setting is one minute.

History is available for all sensors, but only the set value is shown in the display for the room sensor. The integral value that may appear is the heating system’s energy balance.

1.7

INTEGRAL

The heat demand in the house depends on the season and weather conditions and is not constant. The heat demand can be expressed as temperature difference over time and can be calculated giving an integral value as a result (heat demand). To calculate the integral value, the control system uses several parameters.

A heat deficit is needed to start the heat pump, and there are two integral values, A1 (default value = -60), which starts the compressor and A2, (factory set = -600), which starts the auxiliary heater and A3, which starts the external auxiliary heater. During heat production, the deficit reduces and when the heat pump stops, the inertia in the system causes a surplus of heat.

VMGFX202 Danfoss Heating Solutions

Technical description Domestic heat pumps

The integral value is a measurement of the area under the time axis and is expressed in degree minutes. The figure below shows the factory settings for the integral values that the heat pump has. When the integral value has reached the set value for INTEGRAL A1 the compressor starts. If the integral value does not reduce but continues to increase the internal additional heat will start when the integral value reaches the set value for A2 and the external value at set value for A3

The calculation of the integral value stops during heat stop. The calculation of the integral value stops when heat stop has stopped.

In this example INTEGRAL A3 < INTEGRAL A2. This means that the external addition will be activated earlier than the internal addition.

On the condition that these are activated.

HYSTERESIS

In order to start the heat in advance during sudden changes of the heat demand, there is a value, HYSTERESIS, which controls the difference between the actual supply temperature, t

1

and the calculated supply temperature, t

2

. If the difference is equal to or greater than the set HYSTERESIS value (x), i.e. there is a heat demand, or the heat demand disappears, quicker than the usual integral calculation, the integral value is forced to either the start value (-60) INTEGRAL A1 or to the stop value (0).

DEFR CURVE

To start defrosting the outdoor unit, the control computer makes a calculation using the temperature of the brine return and the outdoor temperature.

The calculation is based on a linear defrosting curve that can be set so that the heat pump and outdoor unit work optimally. The setting of three different values can be changed: DEFR CURVE 0, DEFR CURVE -20 and OUTDOOR STOP. The defrosting sequence starts when the temperature of the brine return reaches the set parameter value for the defrosting curve at an outdoor temperature somewhere along the defrosting curve.

The two parameters that are mainly changed are DEFR CURVE 0 and DEFR CURVE -20. The numbers behind the DEFR CURVE display what outdoor temperature the setting is for, that is to say at 0°C for DEFR CURVE 0 and -20°C for DEFR CURVE -20. The value -20 for DEFR

CURVE -20 is the set value for OUTDOOR STOP, so if the value for OUTDOOR STOP changes, the numbers behind DEFR CURVE also change.

Factory setting for OUTDOOR STOP is -20°C. At this outdoor temperature, compressor operation is stopped and the additional heater takes over. Generally the value of OUTDOOR STOP does not need to be changed. Tests and operating cases have shown that -20°C operates very well as the stop temperature. In the text and figures below the value -20°C has been used for OUTDOOR STOP.

The display shows the value for DEFR CURVE 0 and DEFR CURVE -20 by means of a graph.

The value for OUTDOOR STOP corresponds to the fact that the compressor will no longer be used for heating or hot water production if the outdoor temperature is the same as or lower than the value. Heating and hot water production will then be produced with the help of the auxiliary heater.

The value for DEFR CURVE 0 is the temperature that the brine return is permitted to reach when a defrost must start at outdoor temperature 0°C.

In the corresponding way the value for DEFR CURVE -20 is the temperature that the brine return has when a defrost should start at the set outdoor temperature for OUTDOOR STOP. The setting for DEFR CURVE –20 means that the value OUTDOOR STOP (-20°C) is reduced by between 1 and 8 degrees. This also determines how much lower the temperature for the brine return may be than -20°C in this case.

These three settings together create the defrosting curve and all three values have an effect on when defrosting will start, even if it is mainly DEFR CURVE 0 and DEFR CURVE -20 that is changed.

2 Check and safety functions

The heat pump has a number of check and safety functions to protect the installation against damage during abnormal operating conditions.

The diagram below shows the heat pump's three circuits with respective safety functions.

Heat transfer fluid circuit (1)

If the pressure in this circuit exceeds the opening pressure for the safety valve (2), the valve opens, releases the overpressure and closes again. The safety valve overflow pipe must have an open connection to the drain and visibly flow into this in a frost-free environment.

Refrigerant circuit (3)

The refrigerant circuit's high pressure side is equipped with a high pressure switch (6) and one or two operating pressure switches (4, 5), only one of which is connected. The connected operating pressure switch stops the compressor when the working pressure is reached, which is when sufficient heat energy has been produced.

If the operating pressure switch does not work and the pressure continues to increase in the circuit, the high pressure switch activates when its break pressure is reached, whereupon the compressor stops and the heat pump's normal operation is blocked.

VMGFX202 Danfoss Heating Solutions

Technical description Domestic heat pumps

If the high pressure switch is activated an alarm indicator flashes on the heat pump's control panel and a warning text appears in the display of the control panel. The blocked heat pump is reset by setting the operating mode to OFF and then back to the previously selected mode.

The low pressure switch (7) stops the compressor and blocks the heat pump's operation if the pressure becomes too low in the cooling circuit's low pressure side.

If the low pressure switch is activated, the heat pump's normal operation is blocked, an alarm indicator on the heat pump's control panel flashes and a warning text appears in the display of the control panel. The blocked heat pump is reset by setting the operating mode to

OFF and then back to the previously selected mode.

Brine circuit (8)

If the pressure in this circuit exceeds the opening pressure for the safety valve (9), the valve opens, releases the overpressure and closes again. The safety valve overflow pipe must have an open connection to the drain and visibly flow into this in a frost-free environment.

Compressor

The compressor is equipped with a thermal over current relay to protect it against over current.

If the thermal over current relay (position 1 in the image below) is activated, the heat pump's normal operation is blocked, an alarm indicator on the heat pump's control panel flashes and a warning text appears in the display of the control panel.

The blocked heat pump is reset by setting the operating mode to OFF and then back to the previously selected mode.

The compressor is also equipped with an internal protector that stops the compressor if it risks becoming overheated. The internal protector cannot be reset manually, the compressor must cool before it can be restarted. No alarm connected to this protector.

Circulation pumps

The circulation pumps have internal overload protectors, which are reset automatically after cooling.

The overload protectors in circulation pumps for 10 - 16 kW heat pumps also activate the alarm for motor protection and block the heat pump's normal operation. Indication and resetting occur in the same way as for the compressor.

Alarm mode

If an alarm that affects the heat pump's normal operation is activated this will be indicated in the display. In order to further attract attention, the heat pump will not produce hot water.

The heat pump will initially meet the heat demand using the compressor. If this is not possible, the built-in electric heating element engages (provided that heat pump is run in auto mode).

Immersion heater, electric heating element

The immersion heater consists of an electric heating element mounted on the heating system supply line. It has an overheat protector that switches off the electric heating element if it is at risk of becoming overheated. The overheat protector's control unit is on the electrical panel (position 2 in the image below).

If the overheat protector is activated an alarm indicator flashes on the heat pump's control panel and a warning text appears.

The overheat protector is reset by pushing the reset button (position 3 in the image below).
