Problems solved by technology

The mechanical subcooling cycle needs to be coupled with an auxiliary cycle on the basis of the main cycle. However, the existing two-stage compression generally uses two compressors in series or a single compressor in series with two cylinders. It is necessary to add an auxiliary cycle compressor, which increases the Cost, size and control complexity

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] Such as Figures 1 to 2 As shown, the air conditioner according to the present invention includes a compressor 1 and a main loop and an auxiliary loop connected to the compressor 1. The compressor includes a first compression chamber A, a second compression chamber B and a third compression chamber C. A compression chamber A and a second compression chamber B are set in the main circuit, and the third compression chamber C is connected in series in the auxiliary circuit; the main circuit also includes the condenser 3, the evaporator 2 and the condenser 3 and the evaporator 2 The supplementary air device 5 for supplying air to the compressor 1 is used in between; the auxiliary circuit cycle also includes an auxiliary road condenser 901 for supplying heat to the refrigerant entering the air supplement device 5 and an auxiliary road evaporator 902 for ...

Abstract

The invention provides an air conditioner. The air conditioner comprises a compressor, and a main cycle and an auxiliary cycle which are connected with the compressor, wherein the compressor comprises a first compression chamber, a second compression chamber and a third compression chamber, the first compression chamber and the second compression chamber are arranged in the main cycle, and the third compression chamber is serially connected in the auxiliary cycle; the main cycle further comprises a condenser, an evaporator and an air compensation device which is connected between the condenser and the evaporator and is used for compensating air to the compressor; the auxiliary cycle further comprises an auxiliary condenser which is used for heating refrigerant entering the air compensation device and an auxiliary evaporator which is used for refrigerating the refrigerant entering the evaporator. The air conditioner has the advantages that since the compressor is provided with three compression chambers, the first compression chamber and the second compression chamber are arranged in the main cycle and the third compression chamber is serially connected in the auxiliary cycle, when the compressor works, the refrigerant in the main cycle and the refrigerant in the auxiliary cycle are simultaneously compressed, one compressor is saved, and the costs, the size and the control complexity are further reduced.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner. Background technique [0002] The heating capacity of the air source heat pump decays rapidly as the outdoor ambient temperature drops and cannot meet the needs of users. The existing technology of double-stage or quasi-two-stage compression with air supplementation and enthalpy increase, including two-stage throttling intermediate incomplete cooling and one-stage throttling intermediate incomplete cooling cycle, to improve low-temperature heating capacity and COP, while reducing compressor exhaust air temperature. However, in the prior art, the ratio of supplementary air to increase enthalpy is not high, so the effect of supplementary air to increase enthalpy on improving the heating coefficient of performance is not obvious; when the outdoor ambient temperature is very low in cold winter, the heating capacity still cannot meet the requirements. [0003] Uti...
