Hot water and supercooling heat pump system using a thermal stratification type hot water tank

摘要

The present invention relates to a hot water supply system and a supercooled heat pump system using a temperature stratification type hot water tank for supplying hot water using surplus energy by a simple structure and preventing the overcooling of the apparatus and greatly improving the efficiency of the apparatus. According to the present invention, there is provided a heat pump system including a compressor (33), a condenser, an expansion valve (34) and an evaporator interconnected by a circulation line (20) through which a heating medium is circulated; A heat source supply line 21 connected to the circulation line 20 and operated to operate as the condenser or the evaporator during cooling or heating operation and in which the heat source water is circulated so that heat exchange with the heat source S side including the geothermal heat is performed, A first heat exchanger (31) connected to the first heat exchanger; A second heat exchanger (32) corresponding to the first heat exchanger (31) and adapted to operate as an evaporator or a condenser, and connected to the load (R) side by a load supply line (22) to supply cooling and heating; A hot water supply line 23 connected to the circulation line 20 so as to be positioned between the first heat exchanger 31 and the second heat exchanger 32 to supply the hot water H through heat exchange with the heat medium, A hot water and supercool heat exchanger (35) connected to flow the heat medium on the circulation line (20) and the flow of hot water on the hot water supply line (23) in opposite directions; A temperature-stratified-type (not shown) which is provided as a single tank for storing hot water heated by the hot water supply and supercooling heat exchanger (35), and which is filled with high-temperature water having a temperature difference from the low- A hot water and supercooling heat pump system including a hot water tank 40 is provided.
