Abstract

The invention relates to the technical field of air conditioning devices, in particular to a device and method for detecting the quantity of refrigerants and an air-conditioner with the device for detecting the quantity of the refrigerants. The device for detecting the quantity of the refrigerants comprises a plurality of temperature sensors, a temperature collection meter and a calculation terminal. The temperature sensors are installed on the air-conditioner and electrically connected with the temperature collection meter. The temperature of the middle of a condenser, the temperature of an outlet of the condenser, the temperature of an inlet of an evaporator and the temperature of an outlet of the evaporator of the air-conditioner are correspondingly measured through the multiple temperature sensors of the device for detecting the quantity of the refrigerants, transmitted into the temperature collection meter of the device for detecting the quantity of the refrigerants through a condenser middle temperature collection wire, a condenser outlet temperature collection wire, an evaporator inlet temperature collection wire and an evaporator outlet temperature collection wire of the device for detecting the quantity of the refrigerants, and then transmitted through the temperature collection meter to the calculation terminal electrically connected with the temperature collection meter for analyzing and calculating the quantity of the refrigerants of a current air conditioning system. The device for detecting the quantity of the refrigerants is simple in structure and convenient to operate and measure, and whether the quantity of the refrigerants of the current air conditioning system is proper or not can be conveniently detected.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a refrigerant amount detection device, an air conditioner with the detection device and a detection method. Background technique [0002] After the air conditioning system is installed, there may be a certain amount of refrigerant leakage in the air conditioning system. After long-term operation, the amount of refrigerant in the air-conditioning system may leak a large amount, resulting in a decrease in system capacity and energy efficiency, and even affecting the reliability of the air-conditioning system. At present, the market lacks a device for independently and automatically detecting the amount of refrigerant in the air-conditioning system, and the existing air-conditioner also lacks a detection device for detecting the amount of refrigerant, which reduces the reliability of the air-conditioning system. Contents of the invention [0003] The technical problem to...
