Ammonia systems. Ammonia, R717 is an attractive refrigerant alternative offering wide application ranges from high to low temperatures and considerably lower cost (per kg) compared to HFC refrigerants. Because of its better heat transfer properties, ammonia requires a lower heat transfer area than most chemical refrigerants.

industrial water chiller, large scale heat pump center and lithium bromide absorption systems. It is capable for steam-liquid or liquid-liquid heat transfer. Under some circumstances, it is far more ecient in heat transfer than the plate heat exchanger. Technical parameter . Thickness/ mm 13+2.7N weight/ kg 13+0.75N Liquid holdup/ L 0.22(N-2)
Influence of the Refrigerant Maldistribution in the Brazed plate heat exchangers (BPHE) are used widely in heating and cooling systems, mainly for liquid-to-liquid heat transfer but also for two-phase-applications like evaporation and condensation. Using them as evaporator or condenser in a heat pump the proper performance of them strongly influences the energy efficiency of the cycle and the required amount of refrigerant. One of the most common factors affecting the performance of BPHE
Consists of 316 stainless steel plats vacuum-brazed together with copper or nickel brazing material to form a highly efficient, compact heat transfer unit.

Alfa Laval brazed plate exchangers. Our copper-brazed plate heat exchangers are a compact, efficient, and maintenance-free solution for heating, cooling, evaporation and condensing in numerous refrigeration applications and with most types of
Brazed plate heat exchanger - air conditioning DanfossThe performance and efficiency of the brazed plate heat exchanger (BPHE) have been proven through 30 years of constant development to ensure high thermal efficiency leading to energy savings in air conditioning systems. With its ingenious construction of corrugated plates, the BPHE offers you one of the most efficient ways to transfer heat
Brazed plate heat exchangers with multi-pass configuration have a number brazed plates grouped together. Groups are then connected in series to each other forming a longer flow-path for fluids. This configutation of plates increases the heat transfer capacity for the same heat exchanger footprint.
