Key selection and maintenance points for thermostat wiring
1. Temperature resistance grade: The wires near the compressor must use high-temperature wires (such as 105°C or even 125°C grades), as ordinary PVC wires (70°C) will age and become brittle under long-term high temperatures, which is extremely dangerous. 2. Insulation and flame retardancy: It is ...Read more -
Thermostat wiring function and structure
The wires for the temperature controllers of air conditioners and refrigerators form a low-voltage, low-current system with extremely high requirements for insulation and reliability. It is not merely a simple power connection; it is a channel for transmitting control signals. I. Core Functions a...Read more -
The principle of the refrigerator evaporator
The working principle of the evaporator is based on the physical law of phase change absorbing heat. It follows the four steps of the entire refrigeration cycle: Step 1: Pressure reduction The high-pressure and normal-temperature liquid refrigerant from the condenser flows through the capillary t...Read more -
The function and structure of the refrigerator evaporator
I. Function The role of the evaporator in the refrigerator cooling system is “absorbing heat”. Specifically: 1. Absorbing heat to achieve cooling: This is its core mission. The liquid refrigerant evaporates (boils) inside the evaporator, absorbing a large amount of heat from the air i...Read more -

The following is a detailed installation, commissioning and maintenance guide: I. Installation Method 1. Location selection Direct contact with heat sources:...Read more -
Introduction to Overheat Protector
An overheat protector (also known as a temperature switch or thermal protector) is a safety device used to prevent equipment from being damaged due to overheating. It is widely applied in fields such as motors, household appliances, and industrial equipment. The following is a detailed introducti...Read more -
The application of Heat Pipes for Water Heaters in refrigerators
Heat Pipes are highly efficient passive heat transfer devices that achieve rapid heat conduction through the principle of phase change. In recent years, they have demonstrated significant energy-saving potential in the combined application of refrigerators and water heaters. The following is an a...Read more -
Common knowledge about Reed Sensor
Reed Sensor is a switch sensor based on the principle of magnetic sensitivity. It is composed of a metal reed sealed in a glass tube. When an external magnetic field acts on it, the reed closes or opens, thereby achieving the on-off control of the circuit. The following are its main features and ...Read more -
The principle and function of the combination of heating tubes and compressors
1. The role of auxiliary electric heating Make up for the insufficiency of low-temperature heating: When the outdoor temperature is too low (such as below 0℃), the heating efficiency of the air conditioner’s heat pump decreases, and even frosting problems may occur. At this point, the auxil...Read more -
Cold facts about air conditioners
Air conditioners were originally invented for printing factories In 1902, Willis Carrier invented the first modern air conditioner, but its original intention was not to cool people down. Instead, it was to solve the problems of paper deformation and ink inaccuracy caused by changes in temperatur...Read more -
What are the temperature control structures inside a refrigerator
The temperature control structure of a refrigerator is a key part to ensure its cooling efficiency, temperature stability and energy-saving operation, and it usually consists of multiple components working together. The following are the main temperature control structures and their functions ins...Read more -
Daily cleaning and maintenance of refrigerators
The daily cleaning and maintenance of refrigerators are of great significance, as they can extend their service life, keep food fresh and prevent the growth of bacteria. The following are detailed cleaning and maintenance methods: 1. Clean the interior of the refrigerator regularly Power off and ...Read more
