Introduction to the principle of bipolar cooling compressor

Two-stage refrigeration can be completed by two hp air compressor, that is, a low-pressure compressor and a high-pressure compressor; it can also be a single two-stage compressor, but the suction and exhaust pipes of the two compressors are all compressed by the same one. on board. Two-stage refrigeration uses the same refrigerant, enters the internal machine evaporator after throttling, exchanges heat with the outside and boils (evaporates heat absorption), and is sucked and compressed into intermediate pressure by the low-pressure compressor (or low-pressure cylinder). After the liquid is cooled (subcooled), it enters the high-pressure stage compressor (or high-pressure cylinder) and compresses it into high-pressure steam, which is discharged into the condenser of the external machine, exchanges heat with the outside, and condenses (exothers heat) to continue throttling into the evaporator of the internal machine. Repeat the cycle. The process flow of a two-stage refrigeration system is more complicated than that of a single-stage refrigeration system, with the addition of an intercooler (intercooler) and a low-pressure accumulator (low-pressure circulation barrel), etc., so there are more pipelines than a single compressor.

1. Quick freezing can be achieved without special refrigerant

In the refrigeration and cold storage industry, small quick-freezers require lower temperatures (generally below minus 40 degrees) to quickly freeze food. It is difficult and laborious to use special refrigerants for general refrigeration compressors. The use of special refrigerants means cold storage. The increase in cost can be easily achieved if a bipolar refrigeration hp air compressor is used. The refrigerant of a bipolar refrigeration compressor does not require a special refrigerant. Generally, the commonly used R22 refrigerant can easily reach below minus 40 degrees, so the bipolar refrigeration compressor is used. It is convenient to use the refrigeration compressor to make the quick-freezer, the refrigeration is fast, economical and guaranteed!

2. High operating efficiency and good economy

For R22 refrigerant, when the compression ratio of the single-stage refrigeration system reaches or exceeds 8, the operating conditions gradually deteriorate, the operating temperature of the compressor is high, the valve cylinders are prone to carbon deposits, and the efficiency (energy efficiency ratio) is low. The economy is poor, which requires the use of two-stage compression to change this situation, improve the cooling efficiency (energy efficiency ratio) and the economics of operation, and keep the working conditions within a reasonable operating range. For example, a system where the refrigeration temperature needs to reach -30 degrees, adopts single-stage refrigeration. When the refrigeration temperature is around -20 degrees, the temperature drops slowly or it is difficult to continue to fall. At this time, the operating temperature of the compressor is high, even hot When the compression ratio of high and low pressure reaches or exceeds 8, the various losses of the system will increase, and the energy efficiency ratio will be greatly reduced. When two-stage refrigeration is used, the compression ratio decreases, the refrigeration temperature drops rapidly, the working condition indicators respond well, and the energy efficiency ratio increases.

With its high efficiency and low loss characteristics, the two-stage refrigeration hp air compressor has the unparalleled superiority of a single compressor. The two-stage refrigeration compressor not only improves the refrigeration efficiency of the compressor, but also greatly saves operating costs, and it can operate normally regardless of the harsh working conditions of high or low temperature, ensuring safety.
