Stacked low-temperature refrigeration unit

A stacked low-temperature refrigeration unit consists of two or more independent refrigeration systems, each of which can use a single-stage or two-stage compression refrigeration system. These two parts are evaporated through a condensation process Connected together, it is both a condenser for low-temperature cycles and an evaporator for high-temperature cycles, where the evaporation of refrigerant in high-temperature cycles is used to condense refrigerant in low-temperature cycles. So, low temperature The heat absorbed by the cycle (refrigerant) is transferred to the refrigerant in the high-temperature cycle, which then transfers the heat to the environmental medium (air or water).

The refrigeration cycle of the stacked low-temperature refrigeration unit can meet the requirements of having suitable evaporation pressure at lower evaporation temperatures and being able to operate at full capacity

Moderate condensation pressure at ambient temperature.

scope of application

Overlapping low-temperature refrigeration units are widely used in rubber, plastics, petroleum, chemical, electronics, papermaking, textiles, brewing, pharmaceuticals, food, machinery, beverages, vacuum coating, electroplating, etc In many fields such as central air conditioning, it is also commonly used in centralized cooling methods to facilitate centralized piping. Low temperature chillers can be customized into acid and alkali resistant models, meeting the special requirements of customers' special processes The demand can also be customized into low-temperature models, combined with low-temperature refrigerant, to meet the special requirements of customers' special processes.
