Cold storage compressors typically use R404A or R507 refrigerant. Both are low-temperature refrigerants suitable for cold storage and other low-temperature environments. R404A is a blend of R125, R143a, and R134a, offering good cooling performance and stability. R507 is an azeotropic mixture of R125 and R143a, with performance similar to R404A but a slightly lower global warming potential (GWP). The choice between them should be based on equipment requirements and environmental factors.
II. Horsepower of the Compressor
The ZB38KQE compressor has a horsepower of approximately 5 HP, with a specific power rating of around 3.7 kW. Horsepower is a common unit for measuring the cooling capacity of a compressor, where 1 HP is approximately equal to 0.735 kW. A 5 HP compressor is suitable for small to medium-sized cold storage facilities, meeting daily refrigeration or freezing needs. In practical applications, factors such as cold storage volume, insulation performance, and operating environment must be considered to ensure the compressor operates efficiently.
III. Common Questions about the Cold Storage Compressor
Compatibility: It can be used with various cold storage equipment, but the piping design and control system must be compatible.
Maintenance Points: Regularly check the lubricant oil and refrigerant charge level to prevent performance degradation due to oil shortage or insufficient refrigerant.
Troubleshooting: If the compressor has difficulty starting or exhibits poor cooling performance, first check the power supply voltage and the cleanliness of the condenser.
