Definitions

  • the present invention relates to a heat pump device.
  • DE 26 38 861 A1 describes a heating system with a heat pump.
  • a heat meter is connected to a flow temperature sensor and a return temperature sensor on the condenser and so can detect the amount of heat generated by the amount of heat.
  • the heat pump device has a refrigerant circuit with a compressor, a low pressure sensor and a high pressure sensor.
  • the high pressure sensor and the low pressure sensor are arranged in front of and behind the compressor and detect the pressure in the refrigerant circuit in front of and behind the compressor.
  • the heat pump device further comprises a regulator having a heat quantity unit for evaluating the amount of heat generated by the heat pump device based on the signals of the low pressure sensor and the high pressure sensor.
  • the heat pump device includes a display unit for displaying the amount of heat evaluated by the heat quantity unit.
  • the heat pump apparatus has an input unit for selecting the period of time for evaluating the amount of heat generated by the heat pump apparatus and selecting which proportion of the heat quantity is to be displayed.
  • the invention relates to the idea to provide a heat pump device with a refrigerant circuit.
  • the refrigerant circuit has a compressor and a low pressure sensor and a high pressure sensor in front of and behind the compressor.
  • the heat pump unit further includes a regulator which is connected to the low pressure sensor and the high pressure sensor.
  • the controller has a heat quantity unit for evaluating the amount of heat generated by the heat pump device based on the signals from the low pressure sensor and the high pressure sensor. Further embodiments of the invention are the subject of the dependent claims.
  • Fig. 1 shows a schematic representation of a heat pump device according to a first embodiment.
  • the heat pump device has a refrigerant circuit with a condenser 10, with an inlet 11 and an outlet 12 (eg for heating water or hot water), an electrical expansion valve 20, a Evaporator 30 and a compressor 40 on. Further, a low pressure sensor 110 and a high pressure sensor 120 are provided.
  • a 4-2-way valve 50, a filter dryer 60, a sight glass 70 and injection capillaries 80 may be provided.
  • the heat pump device further comprises a regulator 90.
  • the controller 90 is coupled to the low pressure sensor and the high pressure sensor 110, 120 and receives the output signals from these sensors.
  • the controller 90 may include a heat quantity unit 91 for determining the amount of heat generated by the heat pump device.
  • the heat quantity unit 91 calculates the absorbed heat quantity based on the output signals of the low pressure sensor and the high pressure sensor 110, 120.
  • the heat pump device may include an input unit and an output unit.
  • the determined amount of heat can be displayed or output.
  • the period for the calculation of the amount of heat can be selected.
  • the amount of heat for the heating per day can be displayed, which is generated by the compressor.
  • the total amount of heat of the heater generated by the compressor may be displayed.
  • an amount of heat for hot water per day can be displayed, which is generated by the compressor.

  • the total amount of heat of the heater which is generated by an auxiliary heater, such as a water heater, can be displayed.
  • the total amount of heat of the hot water can be displayed, which are generated by an additional heating, such as a water heater.
  • the electric power consumption of the compressor per heater per day can be displayed.
  • the total sum of the electric power consumption of the compressor for the heating can be displayed.
  • the electric power consumption of the compressor for hot water per day can be displayed.
  • the total sum of the electric power consumption of the compressor for hot water can be displayed.
  • the heat quantity unit 91 may calculate the heat quantity of the heat pump according to the following equation.
  • Q. C p_ 0 * a - b * p_C * 1 - e + p_ 0 * C + p_C * d + e * e
  • the electric power consumed by the heat pump device can be calculated by the following equation.
