Common types and locations of heating tubes found in refrigerators
There is usually not just one heating tube in the refrigerator, but they are distributed in different positions according to their functions. 1. Frost-removal heating tube – The most important heating tube Position: Close to the bottom of the evaporator or interspersed among the evaporator ...Read more -
Why does a refrigerator need a heating element?
This might sound counterintuitive – why would a cooling device need to be heated? The key lies in defrosting and preventing moisture. 1. Defrosting (for air-cooled refrigerators): The air-cooled refrigerator uses a fan to blow the cold air from the evaporator into the compartments. When the...Read more -
How to select the temperature sensor in an induction cooker
Focus on basic functions and cost: If your requirement is for basic overheating safety protection and you are sensitive to cost, traditional NTC thermistors are a mature and reliable choice. Seek intelligent cooking and precise temperature control: If you want the induction cooker to have more in...Read more -
Parameters and features of the overheat protector ST-22
ST-22 is a widely used automatic reset type overheat protector (also known as a temperature switch or thermostat), mainly used to prevent electrical equipment such as motors and transformers from being damaged due to overheating. Operating temperature range: 70°C – 150°C (common range, some...Read more -
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 -
Usage method of overheat protector
The correct usage method of the overheat protector (temperature switch) directly affects the protection effect and safety of the equipment. 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
