Embodiment Construction

[0038] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0039] The invention provides a centrifugal air conditioning unit with water as the refrigerant, such as figure 2 As shown, it includes: an evaporator 5, a compressor, a motor, and a condenser 6 arranged in a fully enclosed container 1, and a first circulation channel arranged outside the container 1 through which the condenser 6 supplements the evaporator 5 with refrigerant water The evaporator 5 can evaporate the refrigerant water circulating through the evaporator circulating pump 7 while exchanging heat with the outside through the internal indirect contact heat exchange method; the compressor can be driven by the motor and suck in the evaporation through the suction end The low-temperature water vapor generated by the device 5 compresses the low-temperature water vapor, and then discharges the high-temperature water vapor thro...

Abstract

Provided are an air conditioning unit and an operation method. The air conditioning unit comprises an evaporator (5), a compressor and a condenser (6) provided in one common totally-enclosed container (1). A first circulation channel through which the condenser (6) provides a liquid circulation working medium for the evaporator (5) is further provided at the outer side of the container (1), and the evaporator (5) can exchange heat with the outer side in an internally indirect contact heat exchange manner while evaporating the liquid circulation working medium driven by an evaporator circulating pump (7); the compressor can suck in a low temperature gas circulation working medium produced by the evaporator (5) through a gas suction end, then compresses the low temperature gas circulation working medium, and thereafter discharge a high temperature gas circulation working medium through a discharge end; and the condenser (6) can transform the high temperature gas circulation working medium into the liquid circulation working medium in an internally indirect contact heat exchange manner.

Description

Technical field [0001] The invention relates to the field of air conditioning, in particular to a centrifugal air-conditioning unit using water as a refrigerant and an operating method. Background technique [0002] Using water as the refrigerant of the centrifugal air conditioning unit, compared with other refrigerants, it has the advantages of safety, environmental protection, non-toxic, non-flammable, low cost, easy access, no need for oil circulation, etc. It has great research value and market prospects. . [0003] At present, the main technical solutions adopted by centrifugal air-conditioning units that use water as the refrigerant are as follows: figure 1 As shown, two compressors are provided in the compressor container 1a, the first-stage compressor 2a is driven by the first-stage compressor motor 4a, the second-stage compressor 3a is driven by the second-stage compressor motor 5a, the evaporator 7a and the condenser 6a They are connected by pipes with throttling devices...
