Problems solved by technology
[0002] Existing water chillers have the following disadvantages: 1. The degree of subcooling of the condenser cannot be automatically controlled. At present, in order to increase the degree of subcooling, an intermediate heat exchanger is generally added to the chiller, because the heat exchange medium in the intermediate heat exchanger is Low pressure refrigerant vapor and high pressure refrigerant liquid, so that the effect of increased subcooling is limited
2. The compressor in the flooded water chiller is easy to absorb liquid, which will easily cause the compressor to run out of oil and compress the compressor liquid, causing damage to the compressor. In order to avoid the compressor with liquid in the current flooded chiller, The evaporator cylinder is made very large, and the arrangement of the heat exchange tubes is very low, resulting in an increase in the cost of the heat exchanger

The invention discloses a water cooling unit comprising a compressor, a condenser, a high-pressure float ball, a low-pressure liquid collector, an evaporator and a throttle element. The compressor is provided with an exhaust hole and a gas return hole. An inlet of the condenser is connected with the exhaust hole of the compressor. The high-pressure float valve is connected with an outlet of the condenser so that liquid level of the condenser can be adjusted. The low-pressure liquid collector comprises a liquid inlet and a liquid outlet; the liquid outlet is connected with the gas return hole of the compressor. An inlet of the evaporator is connected with the high-pressure float valve through a pipeline; part of the pipeline is arranged inside the low-pressure liquid collector. The throttle element is arranged on the pipeline, adjacent to the inlet of the evaporator. The outlet of the condenser of the water cooling unit has a certain degree of supercooling, supercooling effect of high-pressure refrigerant liquid is improved, suction and liquid entrainment of the compressor are prevented, refrigerating capacity and energy-efficiency ratio of the water cooling unit can be increased, and the life of the compressor is prolonged.
Description
Technical field [0001] The present invention relates to the field of refrigeration equipment, in particular to a chiller. Background technique [0002] The existing water chillers have the following shortcomings: 1. The subcooling degree of the condenser cannot be automatically controlled. At present, in order to increase the subcooling degree, an intermediate heat exchanger is generally added to the cold water unit, because the heat exchange medium in the intermediate heat exchanger is Low-pressure refrigerant vapor and high-pressure refrigerant liquid make the effect of increasing the degree of subcooling limited. 2. The compressor in the full-liquid chiller is prone to inhale air and liquid, which can easily cause the compressor to run off oil and compress the compressor liquid, causing damage to the compressor. The current full-liquid chiller is to avoid the compressor with liquid. The evaporator cylinder is made very large, and the arrangement of the heat exchange tube is v...
