Abstract

The invention provides a control method for enhanced vapor injection of an air conditioner system. The control method for enhanced vapor injection of the air conditioner system comprises the following steps of detecting pressure of the system; acquiring first pressure data of the system; and adjusting the opening degree of an electronic expansion valve according to the first pressure data so as to adjust enthalpy enhancing amount of a compressor. By the control method, the problems that the adjustment precision is poor and the enthalpy enhancing effect is not obvious in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method for increasing enthalpy by air injection in an air conditioning system. Background technique [0002] At present, with the continuous improvement of consumers' requirements for quality of life, the demand for high-energy-efficiency air-conditioning products is increasing day by day. As an air-conditioning system with high energy efficiency and high water temperature heating, the air-jet air-conditioning system occupies an increasingly important position in air conditioning. [0003] The control method of the air-injection enthalpy-increasing air conditioning system in the prior art generally detects the relevant temperature parameters through the temperature-sensing package, and throttles the flow through the capillary to control the enthalpy increase of the system. In the prior art, the temperature parameter is used as a reference, and its adjustment a...
