WATER HEATING AND COOLING MODULE FOR WATER FILTERING MACHINES

Abstract

The invention relates to a water heating and cooling module (2) composed of: a cooling tank (21); a compressor (22); a heat pump tank (23); an auxiliary condenser (24); a expansion valve assembly (25); and a heating tank (26), in which the cooling tank (21) and the heat pump tank (23) are integrated into a sealed unit composed of a thermal insulation shell. The heat pump tank (23) is composed of: a rectangular heat pump tank chamber (231); a coiled heat exchanger (232) in the form of a spring-shaped tube, located near the bottom of the heat pump tank chamber (231) and having a gas inlet (232a) connected to the compressor outlet (22) and a gas outlet (232b) connected to the inlet of the auxiliary condenser (24); The filtered water inlet (233) is constructed in the form of a long pipe with the inlet (233a) connected to the filtered water outlet of the filter block (1) and the outlet (233b) is located below the heat exchanger (232) horizontally; the hot filtered water outlet (234) is constructed in the form of a port located on the top surface.This invention utilizes the heat from the condensation process to preheat water, thereby saving up to 20% of energy for water cooling and up to 60% of energy for water heating in water purifiers.
