Commercial Refrigeration

Alfa Laval’s wide range of heat exchangers is found in numerous residential and commercial climate applications – including air conditioning (chillers), tap-water heating (boiler/solar), heat pumps and transport refrigeration.

Condensing
Alfa Laval suggests copper brazed plate heat exchangers or shell-and-tubes heat exchangers for refrigeration applications. Copper brazed plate heat exchangers are maintenance free and provide efficient heat transfer with a small footprint. Shell-and-tube heat exchangers are designed for air conditioning and industrial refrigeration systems for cooling fluids. They consist of a shell with traditional plain tubes or enhanced surface tubes for high thermal performance.
Sub-cooling
Subcoolers can be used to increase capacities, and/or decrease power consumption, by lowering liquid temperature into the expansion valve with a separate heat exchanger. The lower temperature to the expansion valve means that less refrigerant has to evaporate in order to reach the evaporation temperature. Consequently, more liquid refrigerant is available in the evaporator, and its capacity increases. The increased efficiency of the compressors means that less compressor power is necessary.
