Problems solved by technology

[0002] Refrigerant shortage and system blockage are one of the common failures of air conditioners, which not only reduce the cooling and heating effect, but also increase the exhaust temperature
When the exhaust temperature is high, the refrigerant and lubricating oil will be thermally decomposed, which will not only deteriorate the lubrication conditions, but also produce impurities such as water, acid, carbon, etc., which will cause system blockage, copper plating of the compressor, cylinder jamming and even burn-out, etc. nasty accident
When the refrigerant is missing or the system is blocked, it often feels that the cooling speed is slowe

Abstract

This invention relates to an air conditioner and a failure diagnosis method. The air conditioner has a failure diagnosis function, which comprises a compressor, an outside heat exchanger, a restricting element, an inner heat exchanger, a central process unit, a coolant wantage or system blockage diagnosis mechanism; wherein the diagnosis mechanism comprises a pipe temperature sensor, an environmental temperature sensor and a comparison unit, and the pipe temperature sensor is set in the coolant pipe of the indoor heat exchanger, the environmental temperature sensor is in the windward of the indoor heat exchanger, and the comparison unit is connected with the central process unit.

Description

technical field [0001] The invention relates to an air conditioner and a fault diagnosis method for the air conditioner, in particular to an air conditioner with the function of diagnosing the faults of lack of refrigerant and system blockage and the diagnosis method for the fault of lack of refrigerant in the air conditioner and system blockage. Background technique [0002] Lack of refrigerant and system blockage are one of the common failures of air conditioners, which not only reduce the cooling and heating effect, but also increase the exhaust temperature. When the exhaust temperature is very high, the refrigerant and lubricating oil will be thermally decomposed, not only the lubrication condition will deteriorate, but also impurities such as water, acid, carbon will be produced, which will lead to system blockage, copper plating of the compressor, cylinder jamming and even burnout, etc. vicious accident. When the refrigerant is lacking or the system is blocked, it oft...
