Problems solved by technology

[0008] The invention realizes the even distribution of the gas-liquid two-phase refrigerant by throttling the expansion valve through three connected circulation circuits, thereby solving the problem of using the condenser as a liquid subcooling evaporator to evenly distribute the single liquid refrigerant inside the evaporator, and avoiding that the area of ​​the heat exchanger is not fully covered. Utilization, thereby increasing the effective working area of ​​the condensing heat exchanger and avoiding energy waste

Abstract

The invention relates to the technical field of heat pump units, in particular to a heat pump unit and a gas-liquid two-phase uniform distribution method. The heat pump unit comprises a compressor, an oil separator communicating with the compressor, a condenser communicating with the oil separator, and a parallel two-phase flow distribution type evaporator communicating with the compressor; a first ball valve, a drying filter, an electronic expansion valve and a second ball valve are sequentially arranged between the condenser and the parallel two-phase flow distribution type evaporator to form a first loop; an oil return angular ball valve and an oil return filter are sequentially arranged between the oil separator and the compressor to form a second loop; an oil return electromagnetic valve, a jet pump and a compressor input end ball valve are sequentially arranged between the parallel two-phase flow distribution type evaporator and the compressor; and the jet pump communicates with the condenser to form a third loop. The heat pump unit has the beneficial effect that uniform distribution of expansion valve throttling gas-liquid two-phase refrigerants can be achieved.

Description

technical field [0001] The invention relates to the technical field of heat pump units, in particular to a heat pump unit and a method for evenly distributing gas-liquid two-phase. Background technique [0002] With the rapid development of society and the improvement of people's living standards, the proportion of energy consumption of air conditioning system in the whole social life is increasing, and sometimes it even becomes the main part of the production cost of enterprises. The energy costs are huge and the potential for energy savings is huge. In the traditional air-conditioning system, the air-conditioning unit adopts a flooded system and a liquid-distributed falling-film system heat pump unit. [0003] For example, the patent No. CN204494887U discloses a low-temperature type flooded energy tower heat pump unit, which uses the flooded energy tower heat pump unit to realize heating, cooling and other technologies, but due to the change of the liquid level of the flo...
