Air conditioner and control method thereof

Abstract

The invention provides an air conditioner and a control method thereof, which can find the leakage of an air conditioning system in time and protect the safety of users. The air conditioner comprises a control system, an outdoor unit and an indoor unit, wherein the control system comprises a refrigerant leakage control module which comprises more than one temperature sensor arranged on an indoor heat exchanger or an outdoor heat exchanger and more than one pressure sensor arranged on a lower-pressure part of a circulation pipe, and the temperature sensors and the pressure sensors are respectively and electrically connected with the refrigerant leakage control module.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air conditioning, and in particular relates to an air conditioner and a control method thereof. Background technique [0002] R290 (propane), also known as propane, has excellent thermal performance and low price, and R290 is compatible with ordinary lubricating oil and mechanical structural materials, ODP=0, GWP is small, no synthesis is required, and the nature of hydrocarbons is not changed content has no direct effect on the greenhouse effect. Propane has a large cooling capacity per unit volume and is very suitable for small rotary compressors. The main physical properties of propane are very similar to those of R22, and the R22 system can be used without major modification of the original machine and production line. It can be directly filled with propane, which is a direct substitute. R290 is currently internationally recognized as the best environmental substitute for CFC-12. ...
