Integrated water-cooling low-temperature type air-cooling heat pump module unit

Abstract

The invention discloses an integrated water-cooling low-temperature type air-cooling heat pump module unit which comprises a small cooling tower shell, a cooling system, a refrigerant circulating system and a functional module. 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 typeheat exchanger, an open spiral winding type condenser, an indoor side heat exchanger and a gas-liquid separator; the functional module comprises a liquid storage tank, a drying filter, an economizer and a plurality of electronic expansion valves which are connected with one another; and the low-power compressor is connected with the open spiral winding type condenser, a three-way valve and the aircooling fin type heat exchanger through a four-way valve and then is divided into a main loop and an auxiliary EVI loop. The main loop is connected with the low-power compressor through the functionmodule, the indoor side heat exchanger and the gas-liquid separator, and the auxiliary EVI loop is directly connected with the low-power compressor through the function module.

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...

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide an integrated water-cooled low-temperature air-cooled heat pump modular unit, which solves the problem of large cooling water consumption and low heat exchange efficiency of the chiller, and the large area of ​​the water-cooled chiller machine room occupies indoor space and leads to building utilization. Reduced waste, the cooling pipe network is too long due to the separation of the cooling tower and the chiller, the construction is difficult, the construction cost increases, the large chiller is not easy to transport, install, and maintain, and the high energy consumption of the cooling pump reduces the overall cooling efficiency of the unit The unit is noisy, prone to noise pollution and other problems, and solves the problem of air-cooled heat pump heating but low cooling efficiency
