Cold water air conditioning unit

Abstract

The invention relates to the technical field of air conditioning, in particular to a cold water air conditioning unit. The cold water air conditioning unit aims to solve the problems that an existingcold water air conditioning unit is low in starting speed in a low-temperature environment, and components are prone to failure. The cold water air conditioning unit comprises a compressor, a condenser, a throttling device, an evaporator, a plurality of electronic components and a solar device, wherein the solar device comprises a solar heat collector, a heat conduction pipe and a first circulating pump, the solar heat collector is provided with a heat collection inlet and a heat collection outlet, the heat conduction pipe communicates with the heat collection inlet and the heat collection outlet, the first circulating pump is arranged on the heat conduction pipe, the heat conduction pipe is filled with heat conduction media, and part of the heat conduction pipe is arranged at the bottom of the outer side of the compressor, the bottom of the outer side of the evaporator or the interior of the evaporator and on the peripheries of part of the electronic components in a coiled mode. According to the cold water air conditioning unit, the starting speed and the operation efficiency of the cold water air conditioning unit can be greatly improved, and the detection stability of electroniccomponents and the control precision of the unit are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cold water air conditioning unit. Background technique [0002] Chilled water air-conditioning units are widely used in various industries. Chilled water air-conditioning units are referred to as chillers, which mainly include compressors, evaporators, condensers, expansion valves, and evaporators usually use shell-and-tube evaporators or sleeve-pipe evaporators. The condenser usually adopts a water-cooled condenser or an air-cooled condenser. During operation, the refrigerant in the evaporator exchanges heat with the brine, and the refrigerant in the condenser exchanges heat with cooling water or outdoor air. [0003] When the unit is shut down in winter, in order to prevent the refrigerant in the evaporator from freezing and damaging the evaporator, it is usually necessary to drain the water in the evaporator. However, when the unit starts running again, it takes a...
