Abstract

The invention relates to the technical field of test devices, and discloses a test device for a superheating degree and a supercooling degree, in order to directly measure the superheating degree and the supercooling degree, and provide the working efficiency. The test device for the superheating degree and the supercooling degree comprises a first processing unit and a screen display unit, wherein the first processing unit is used for computing the superheating degree of a refrigerant at the outlet of an evaporator, and the supercooling degree of the refrigerant at the outlet of a condenser, and sending data of the superheating degree and the supercooling degree to the screen display unit, and the screen display unit is used for receiving the data of the superheating degree and the supercooling degree, and displaying the superheating degree and the supercooling degree on a display screen. The test device is mainly suitable for testing the superheating degree and the supercooling degree of an air-conditioning system.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to a testing device for superheat and subcooling. Background technique [0002] An air conditioning system is a system that deals with the temperature, humidity, cleanliness, and airflow velocity of indoor air. It can enable certain equipment or certain places to obtain air with a certain temperature, humidity and air quality to meet the requirements of users and production processes and improve labor hygiene and indoor climate conditions. In order for the air-conditioning system to achieve these goals, it is necessary to ensure the normal operation of the air-conditioning system, and the conditions for judging its normal operation include many aspects. The difference between the superheat temperature of the refrigerant at the outlet of the evaporator under pressure and the corresponding saturation temperature of the refrigerant at this pressure; the so-called subcooling de...
