Single stage dual stage

Product Introduction

Technical features:

a、 The compression process of refrigerant is divided into two stages, which avoids the increase in power consumption caused by the decrease in compressor volumetric efficiency due to the increase in compression ratio;

b、 Under the same low-temperature conditions, in a two-stage compression refrigeration cycle, the coefficient of performance (COP) and cooling capacity are both improved compared to single-stage compressors, making operation more economical and reliable;

c、 In parallel units, each compressor host is a backup machine for each other. Even if one compressor fails, other compressors can still work normally to ensure the normal operation of the system;

Performance advantages:

a、 Efficient and energy-saving: The average efficiency of parallel units varies depending on the refrigeration system, and is 30-50% higher than that of single unit units; Parallel operation of multiple units can provide multi-level energy regulation, equipped with high-efficiency oil separators, effectively improving the efficiency of heat exchangers; Provide multi suction branch control;

b、 Compact structure: Compressors, reservoirs, and other electronic control equipment are all centralized together, with a highly integrated design concept, greatly saving machine room space;

c、 Reliable operation: All valves, instruments, and self-control components of our company's refrigeration system are made of internationally renowned brands, and self-control valves are all imported products;

d、 High degree of intelligence: The refrigeration equipment operates or stops automatically under microcomputer control, accumulates running time automatically, and the electronic control system has multiple functions such as phase loss protection, compressor thermal protection, high and low pressure protection, etc;

e、 Complete monitoring: mainly composed of unit operation monitoring, fan operation monitoring, and temperature monitoring inside the warehouse;

Application parameters:

a、 Evaporation temperature range: -20 to -30 ℃; Suitable for low-temperature refrigeration;

b、 Optional condensers: evaporative condenser, air-cooled condenser;

c、 Optional evaporator: air cooler, aluminum duct

d、 Refrigerants: R22, R404A, R507A;

e、 Compressor brand: Bitzer, Germany;

f、 Compressor ratio: A maximum of 6 compressor heads can be used for a single unit, and compressor models can be selected for dual temperature and triple temperature regulation;
