The utility model discloses an air conditioner, which relates to the technical field of air conditioners, and is characterized in that a refrigerant adjusting device is arranged between an indoor heat exchanger and an outdoor heat exchanger so as to receive condensed refrigerant and convey the refrigerant to an expansion valve; the refrigerant adjusting device is provided with a first flowing loop, a second flowing loop, a first reversing loop and a second reversing loop, and can store a refrigerant or release the stored refrigerant under the condition that the air conditioner operates in a refrigeration mode or operates in a heating module. Therefore, the amount of the refrigerant circulating and operating in the refrigerant circulating loop is adjusted. According to the air conditioner, the refrigerant adjusting device is arranged in the refrigerant circulation loop, so that the air conditioner can be under different operation working conditions, different compressor operation frequencies and different operation modes, the use amount of the refrigerant circulated by the air conditioner is optimal and can be matched with the operation frequency of the compressor, and the working efficiency of the air conditioner is improved. And the real-time energy efficiency of the air conditioner reaches the most efficient.

The present invention discloses a low-pressure refrigerant liquid supply system and a control method thereof, which belongs to the technical field of steam compression cycle chilled water (heat pump) units, including a chilled water unit system and a bearing liquid supply system. The chilled water unit system includes a refrigerant pump, an evaporator, a condenser, a compressor, a power saver, a throttling mechanism, and a PLC control box. The bearing liquid supply system includes a first bearing lubrication liquid supply path from the condenser liquid collection bag to the compressor bearing and a second bearing lubrication liquid supply path from the condenser liquid collection bag to the compressor bearing. Through the design of the bearing liquid supply system, the influence of the vaporization of the refrigerant on the liquid supply of the refrigerant pump can be avoided as much as possible, the along-the-line / local resistance loss of the pipeline can be reduced, the cavitation margin before the refrigerant pump and the supercooling of the refrigerant can be guaranteed, the low-frequency operation of the refrigerant pump, the insulation of the bearing liquid supply pipeline and the exhaust of the pipeline after the refrigerant pump can effectively solve the adverse effects of pipeline vaporization on the liquid supply.

The application relates to the technical field of heat pumps, in particular to a fluorine cooling and water cooling coupled heat dissipation driving plate system, which comprises a compressor, a first heat exchanger, a second heat exchanger, a first electronic expansion valve and a driving plate radiator, one end of the compressor is communicated with one end of the first heat exchanger, the other end of the compressor is communicated with one end of the second heat exchanger, the other end of the first heat exchanger is communicated with the other end of the second heat exchanger, the first electronic expansion valve is connected in series in a passage communicated between the first heat exchanger and the second heat exchanger, and a water inlet pipe of the first heat exchanger, the driving plate radiator and a water outlet pipe of the first heat exchanger are communicated in sequence. The fluorine cooling and water cooling coupled heat dissipation driving plate system can overcome the low heat exchange efficiency of the existing fluorine cooling heat pump unit, can improve the heat exchange efficiency under the condition that the ambient temperature is relatively low, can reduce the waste of resources, and can improve the energy-saving economy of the system.
