Integrated water-cooling air-cooling heat pump module unit

Abstract

The invention discloses an integrated water-cooling air-cooling heat pump module unit comprises a small cooling tower shell, a cooling system, a refrigerant circulating system and a functional module,wherein the cooling system, the refrigerant circulating system and the functional module are integrated in the small cooling tower shell. The cooling system comprises a fan, a water distributor, a cooling circulating pump, a sprayer, a cooling filler layer and a cooling water tank, and the refrigerant circulating system comprises a low-power compressor, an air cooling fin type heat exchanger, anopen spiral winding type condenser, a four-way valve, an indoor side heat exchanger and a gas-liquid separator; the functional module comprises a liquid storage tank, a drying filter, an electronic expansion valve and a plurality of one-way valves which are connected with one another; the low-power compressor is connected with the air cooling fin type heat exchanger and the open spiral winding type condenser through the four-way valve and then connected with the low-power compressor through the function module, the indoor side heat exchanger, the four-way valve and the gas-liquid separator.

Description

technical field [0001] The present invention relates to the field of air-conditioning equipment, in particular to a refrigeration and heating module unit or a direct expansion (multi-connection) module that is highly integrated with a cooling system and a refrigeration system, multiple parallel-connected small modular installations, and capable of mixing air-cooling and water-cooling methods unit. Background technique [0002] With the development of heat pump technology, low-temperature air-cooled heat pumps are gradually becoming popular, and their cooling and heating functions provide users with more choices. [0003] Since the water-cooled chiller has a significant energy-saving effect compared with the air-cooled chiller, and the chiller with a screw compressor or a centrifugal compressor is mostly used, the cooling capacity of a single unit ranges from hundreds of kilowatts to thousands of kilowatts, and the cooling capacity is powerful. The boiler technology is matur...

AI Technical Summary

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide an integrated water-cooled air-cooled heat pump module unit, which solves the problem of large cooling water consumption, low heat exchange efficiency, and large room area of ​​the water-cooled chiller machine room, resulting in reduced building utilization. Waste, the cooling pipe network is too long due to the separation of the cooling tower and the chiller, the construction is difficult, and the construction cost increases. Large, easy to produce noise pollution and other problems, and solve the problem of low cooling efficiency of air-cooled heat pump heating
