ABSORPTION/COMPRESSION REFRIGERATION UNIT Russian patent published in 2009 - IPC F25B25/02 

FIELD: heating.

SUBSTANCE: invention relates to refrigeration engineering, in particular, to refrigeration units of cooling household systems incorporating high- and low-temperature chambers and high-speed leak tight compressors, as well as absorptive contours. Absorption/compression refrigeration unit contains an absorptive refrigeration contour with an oil cooler coil, absorber, liquid and gas heat exchangers, and condenser-evaporator. The absorption/compression refrigeration unit further contains a compression contour with a compressor, regeneration heat exchanger, in-built evaporators, shell-and-tube heat exchanger and capillary tube, the letter being connected after the regeneration heat exchanger to the absorptive contour evaporator, and generator with electroheater whereto water ammoniac solution is directed after being heated in the oil cooler coil. Outlet branch pipe of cylinder head cooling system is connected to the generator unit at the outlet.

EFFECT: increased cooling capability and power efficiency.
