HEAT PUMP SYSTEM FOR COOLING/HEATING WITH UNDERGROUND HEAT SOURCE USING HEAT PIPE HAVING TWO HEADERS

摘要

PURPOSE: A heat pump system for cooling and heating with the underground heat source is provided to increase the utility of a heat pump by combining a cooling and a heating system with a heat pump. CONSTITUTION: The heat pump system is composed of:a heat pipe having two headers of an A header and a B header; an evaporator(10) functioned as a heat exchanger of the A header, accepting the refrigerant by a three-way valve(9) when a heat pump is operated to heat a room; a compressor of the heat pump accepting the refrigerant in a state of vapor by making the refrigerant flowing in the evaporator(10) absorb heat.
