Integrated mixed cooling cold water module unit

Abstract

The invention discloses an integrated mixed 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 dry filter and an expansion valve which are connected in sequence, the cooling water tank isarranged 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 are arranged 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 condenser issoaked 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 that is highly integrated with a cooling system and a refrigeration system, multiple parallel-connected small modular installations, and capable of mixing evaporative cooling and water cooling. Background technique [0002] At present, mainstream refrigeration and 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, so the water-cooled unit can meet the use of medium and large buildings or building clusters. The water-cooled chill...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an integrated mixed-cooling and chilling water module unit, which solves the waste of large cooling water consumption, low heat exchange efficiency, and the large area of ​​the water-cooled chiller machine room occupying indoor space, resulting in reduced building utilization. The cooling pipe network is too long due to the separation of the cooling tower and the chiller, which makes construction difficult and increases construction costs. Large-scale chillers are not easy to transport, install, and maintain. The high energy consumption of the cooling pump reduces the overall cooling efficiency of the unit. The chiller is loud and noisy. Prone to noise pollution and other issues
