Integrated water cooling cold water module unit

Abstract

The invention discloses an integrated water cooling cold water module unit which comprises a small cooling tower shell, a cooling system, a refrigerant circulating system and a functional module. Thecooling 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 and a cooling water tank, and the refrigerant circulating system comprises a low-power compressor, an evaporation cold-heat exchanger, a tube nest soaking type condenser, an indoor side heat exchanger and a gas-liquid separator; the functional module comprises a liquid storage tank, a drying filter and an expansion valve which are connected in sequence; the cooling water tankis arranged on the upper portion in the small cooling tower shell, and the low-power compressor, the liquid storage tank, the drying filter, the expansion valve and the indoor side heat exchanger arearranged on the lower portion in the small cooling tower shell. The evaporation cold-heat exchanger is arranged above cooling water of the cooling water tank, and the tube nest soaking type condenseris soaked in the cooling water of the cooling water tank; and the water distributor is arranged at the bottom in the cooling water tank.

Description

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to a refrigeration module unit or a direct expansion (multi-connection) module unit in a water-cooled refrigeration mode with a high degree of integration of a cooling system and a refrigeration system, multiple parallel-connected small modular installations. Background technique [0002] At present, the mainstream refrigeration air-conditioning units are mainly single-cooled water-cooled chillers and air-cooled chillers. Because water-cooled chillers can save about 30% of cooling energy compared with air-cooled chillers, they have a significant energy-saving effect, and because chillers generally use screw compressors or centrifugal Compressor, the cooling capacity of a single unit ranges from hundreds of kilowatts to thousands of kilowatts. Based on the above advantages, water-cooled chillers are the first choice for summer refrigeration and air conditioning, and are wide...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an integrated water-cooled chilled water module unit, which solves the waste of large cooling water consumption, low heat exchange efficiency, and large indoor space occupied by the water-cooled chiller machine room, resulting in reduced building utilization. The cooling pipe network is too long due to the separation of the tower and the chiller, which makes the construction difficult and increases the construction cost. The large chiller is not easy to transport, install, and maintain. The high energy consumption of the cooling pump reduces the overall cooling efficiency of the unit, and the water splashing of the cooling water tower is serious, etc. question
