The functions of the compressor and the heating tube at each stage
The system switched the flow direction of the refrigerant through a component called “four-way valve”. At this point, the compressor still compressed the refrigerant into a hot and high-pressure gas, but it was first pumped into the heat exchanger of the indoor unit (which functioned ...Read more -
How do the compressor and the heating tube work together?
The compressor and the heating tube are two components with completely different functions, and they play a core role in the cooling and heating systems. Their “cooperative operation” is mainly manifested in the heat pump system of air conditioners. To ensure a thorough understanding,...Read more -
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
