ADVANCED HEAT PUMP WATER HEATER WITH HOT WATER RECYCLING CIRCUIT

摘要

PURPOSE: An advanced heat pump water heater using hot water recycling circuit is provided to freely control temperature of hot water needed. CONSTITUTION: A condenser comprises a high temperature condenser(3) and a preheating condenser(4). The preheating condenser is formed on one side of an outside of a water tank(10) to preheat cold water introduced into the water tank and store. The high temperature condenser is formed on the other side of the outside of the water tank to re-heat water preheated and stored in the water tank to high temperature. The high temperature condenser and the preheating condenser are formed in spiral structure with two rows in cylindrical pipes which water passes, respectively.
