Modular phase-change cooling air conditioning unit

Abstract

The invention discloses a modular phase-change cooling air conditioning unit. The modular phase-change cooling air conditioning unit comprises a first module, a second module and a condenser; the first module is separably mounted on the second module; the second module comprises a host system, a control system, a power distribution system and an air treatment system, wherein the host system comprises a compressor, a throttle valve, a flash tank, a first circulating pump and an evaporator; the compressor, the condenser, the throttle valve and the flash tank are connected to form a primary refrigerant circulation loop; the flash tank, the first circulating pump and the evaporator are connected to form a secondary refrigerant circulating loop; and the air treatment system comprises an air supply pipeline, an air return pipeline and a second fan. The modular phase-change cooling air conditioning unit has the advantages that a cooling tower, a host unit, an air conditioner terminal, the control system, the power distribution system and the like are modularly integrated and designed around a single variable-frequency centrifugal compressor unit, factory prefabrication is achieved, the installation process is simplified, deployment is rapid, and the installation period is shortened; and a variable-frequency centrifugal compressor is adopted, so that the refrigerating efficiency and the operation reliability of an air-conditioning system are improved.

Description

technical field [0001] The application relates to the field of air-conditioning and refrigeration, in particular to a modular phase-change cooling air-conditioning unit. Background technique [0002] The air-conditioning and refrigeration system includes a cooling system, a main unit and an air-conditioning terminal. The cooling system is generally placed outdoors, and the main unit is placed in a dedicated machine room, which occupies a large area. Since each equipment is transported in parts and installed on site, the installation process is complicated and the construction The cycle is long; and the distance from the cooling system to the main unit is long, the cooling water running pipeline is long, the cooling capacity and the water pressure head loss along the way are large; the distance between the main unit and the end of the air conditioner is also long, and the refrigerant connection pipeline is relatively complicated. Contents of the invention [0003] The purpo...
