According to the present invention, an absorption type refrigeration system separates refrigerant and an absorbent concentrated solution by using a reverse osmotic separation membrane or a membrane evaporation separation membrane to improve efficiency without an additional heat source. Moreover, a cooling fluid supplied to the reverse osmotic separation membrane is used to cool a weak solution. Therefore, an absorber needs not to be separately cooled. According to the present invention, a structure of the system is simple to be miniaturized, and can be conveniently manufactured, installed, maintained, and repaired. Moreover, a separator performs a role of an evaporator to enable a structure to be very simple and improve efficiency. COPYRIGHT KIPO 2019 (A1,A2) Vacuum ...

The present invention relates to a steam production heat pump system, allowing a make-up water preheater to transfer heat between make-up water supplied from the outside and a refrigerant passing through a recuperator. Accordingly, the refrigerant can be additionally super-cooled, and the make-up water can be supplied to a steam generation cycle by being heated, thereby increasing production efficiency. Moreover, a flow rate of make-up water introduced into the make-up water preheater in accordance with the temperature of make-up water supplied from the outside can be controlled, thereby increasing heat exchanging efficiency of the make-up water preheater.
