Refrigerator compressors are mainly driven by motors, and use mechanical structures such as pistons, rotating blades or scroll disks to compress refrigerant gas. During the compression process, the temperature and pressure of the refrigerant rise, and then the heat is released in the condenser, and the heat is absorbed into the evaporator after the pressure is reduced by the expansion valve, so as to achieve the purpose of cooling the inside of the refrigerator.
Household refrigerator: The most common application, for the refrigeration and freezing of household food.
Commercial refrigeration equipment: Such as supermarket freezer, beverage machine, ice cream machine, etc.
Industrial refrigeration: Including food processing, chemical raw material storage and other industrial fields that require a low temperature environment.
Automotive air conditioning: The refrigeration system used in the interior of the car.
Medical equipment: Such as blood storage refrigerators, vaccine coolers, etc.
| Application | Evaporating Temperature | Example |
|---|---|---|
| LBP | -35℃ ~ -15℃ | Refrigerators, Freezers |
| MBP | -20℃ ~ 0℃ | Drinking Fountains, Food Preservation Machine |
| HBP | -5℃ ~ +15℃ | Water Heater, Dehumidifiers |
High efficiency and energy saving: Modern refrigerator compressors usually use high efficiency and energy saving design to reduce energy consumption and reduce electricity costs.
Stable and reliable: High quality compressor has a long service life and good reliability.
Low noise: Using advanced noise reduction technology, low noise during operation, providing a quiet living environment.
Environmentally friendly refrigerants: Many modern compressors use environmentally friendly refrigerants to reduce the damage to the ozone layer.
Intelligent control: Some high-end compressors are equipped with intelligent control system, which can adjust the refrigeration intensity according to actual needs, and further save energy.
A refrigerator compressor is driven by an electric motor to compress low-pressure refrigerant gas into high-pressure, high-temperature gas. This gas then flows through the condenser to release heat, passes through an expansion valve to reduce pressure (cooling it down), and absorbs heat inside the evaporator to cool the refrigerator.
These terms refer to the evaporating temperature ranges of the compressor. LBP (Low Back Pressure) operates between -35℃ and -15℃ for freezers. MBP (Medium Back Pressure) operates between -20℃ and 0℃ for beverage coolers. HBP (High Back Pressure) operates between -5℃ and +15℃ for dehumidifiers and water heaters.
They are widely used in household refrigerators, commercial supermarket freezers, industrial low-temperature storage systems, automotive air conditioning units, and specialized medical cooling equipment like vaccine storage units.
Modern compressors feature high energy efficiency, stable and long-lasting operation, low noise emission during cycles, compatibility with eco-friendly refrigerants, and intelligent control systems that adjust cooling output dynamically to save energy.
Compressors are securely packed using standard Pallet packing, Color bag packaging, or Yellow packing methods to prevent movement and damage during transit, ensuring they arrive in optimal working condition.
