Air conditioning unit and method for detecting operation state thereof

Abstract

The invention relates to an air conditioning unit and a method for detecting the operation state thereof. A refrigerant outlet of a compressor and a condenser are respectively provided with a temperature sensor; the measured refrigerant discharge temperature, the condenser temperature and the compressor input power are respectively connected with a difference comparator; and each measured numerical value is compared with the standard value by the difference comparator so as to judge the working conditions of parts such as the condenser, the compressor and the like of the air conditioning unit, and then the working conditions are displayed to users directly by a display to enable the users to learn about the problems in the air conditioning unit intuitively and perform maintenance and partreplacement on the air conditioning unit timely according to the prompt of the display, thus ensuring the air conditioning unit to be a good working state, maintaining the working efficiency of the air conditioning unit in refrigeration and playing a role in saving energy source.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, specifically a temperature sensor is installed at the refrigerant outlet of the condenser and the compressor, and the relationship between the condenser temperature and the discharge temperature of the compressor and the input power is compared by a difference comparator. Thereby judging the problem air conditioner and its running state detection method generated in the operation of the air conditioner. Background technique [0002] Generally, an air conditioner is a device for cooling or heating an indoor environment to create a comfortable indoor environment, and is roughly classified into a window type air conditioner and a split type air conditioner. [0003] Although the functions of the integrated air conditioner and the split air conditioner are the same, the integrated air conditioner is equipped with cooling and heat dissipation components in the same casing, and is inst...

Problems solved by technology

[0007] The air conditioners in the prior art do not have devices and components for detecting the operating status of the air conditioner, so the operating status of each component inside the air conditioner cannot be intuitively known from the outside, and the user cannot know the real operating status of the air conditioner at any time. Understand that when the air conditioner is used for a period of time, it is inevitable that refrigerant leakage, internal parts of the compressor will be worn out, and too much dust will accumulate on the condenser. If the above situations occur, the performance of the air conditioner will decrease and the energy consumption will increase. , but the external manifestations of the above problems are not obvious, and it is not easy for users to perceive, thus resulting in a large amount of energy waste
