  • the refrigerating cycle is a cycle for supplying or absorbing heat to/from a required place by using a circulating cycle of the refrigerant.
  • a compressor, a condenser, an expansion valve, and an evaporator are used.
  • the elements are connected to one another with a refrigerant pipeline, so that the condenser supplies heat to surroundings, or the evaporator absorbs the heat from the surroundings.
  • the condenser and the evaporator are elements for enabling heat exchange between the refrigerant and air or other fluid. Therefore, the elements may be called as heat exchangers, and the condenser and the evaporator are defined depending on states of the refrigerant before and after the heat exchange.
  • a machine or system for heating or cooling room air by using the refrigerating cycle is called as an air conditioner.
  • the air conditioning system in order to heat the room air, the refrigerant supplies the heat to the room air. Therefore, in this case, an indoor unit may be called as a condenser, and an outdoor unit may be called as an evaporator.
  • the refrigerant absorbs the heat from the room air for cooling the room. Therefore, in this case, the indoor unit may be called as an evaporator and the outdoor unit may be called as a condenser.
  • the gas heat pump system realizes the refrigerant cycle by generating power for driving the compressor with an engine which burns gas.
  • US 4 754 614 A relates to a prime-motor-driven room-warming/cooling and hot water supply having a heat exchanger which includes each part of a cooling water circulating circuit, a supplied water circuit, a refrigerant heating circuit and a supplied water heating circuit so as to perform mutual heat exchanging of cooling water for the prime motor in the water heating circuit, the refrigerant in the supplied water heating circuit and the refrigerant in the refrigerant heating circuit.
  • FIG. 1 illustrates a schematic view of a related art gas heat pump system.
  • the related art gas heat pump system may be provided with a compressor 21, an indoor heat exchanger 11, an expansion valve 26, an outdoor heat exchanger 27, and a refrigerant pipeline 30 for connecting above elements together to enable the refrigerant to circulate.
  • An arrangement of the elements and the refrigerant pipeline connecting the elements may be similar or identical to a general air conditioner.
  • the gas heat pump system includes a gas engine 22 for driving the compressor, additionally. Therefore, a cooling water pipeline 40 is required for cooling an overheated gas engine 22.
  • a heat dissipating unit 44 is also used widely for cooling the cooling water heated as the cooling water cools down the gas engine, again.
  • a left side of an A line is an indoor side
  • a right side of the A line is an outdoor side. Therefore, a left side configuration may be an indoor unit 10 and a right side configuration may be an outdoor unit 20, at large.
  • an indoor heat exchanger 11 and a fan 12 may be the indoor unit
  • an outdoor heat exchanger 27, the heat dissipation unit 44, and a fan 45 may be the outdoor unit.

  • the refrigerant vaporized thus is introduced to the compressor through the four-way valve 24, thereby repeating the refrigerating cycle.
  • the cooling water Since a temperature of the cooling water which cools down the gas engine 22 is not high in an initial engine driving, the cooling water is introduced to the engine through the three-way valve 41, again.

  • the refrigerant vaporized thus is introduced to the compressor through the four-way valve 24, to repeat the refrigerating cycle. Therefore, it may be said that a flow direction of the refrigerant flowing along the refrigerant pipeline 30 at the time of room heating is opposite to a flow direction of the refrigerant at the time of room cooling.
  • a flow direction of the cooling water which cools the gas engine 22 flowing along the cooling water pipeline 40 at the time of room heating is the same with a flow direction of the cooling water at the time of room cooling.
