Environmental harmony cool temperature thermal

摘要

PROBLEM TO BE SOLVED: To provide an all-year operated environment-harmonious cold and warm heat supply system contributing to suppression of discharge of a carbonic acid gas and operated with a low temperature exhaust heat by efficiently discharging cold and warm heat through a thermal storage tank all year round, performing energy conserving treatment, and using a natural refrigerant corresponding with environmental harmony. SOLUTION: This environment harmonious cold and warm heat supply system comprises a cold and warm heat supply unit 10 having a main heat pump 11 including a compressor 10a, a water heat source 12, an auxiliary air heat exchanger 13, an ice thermal storage tank 14 having an icemaker 14a and a heat exchanger 14b, and a warm heat thermal storage tank 15 as main components, an adsorption type heat pump 25 having an adsorption type thermal storage tank 22 provided to deal with insufficient warm heat and insufficient cold, a water chiller 24 and a condenser 23, and an auxiliary cold and warm heat supply unit 20 having a vacuum recovery compressor 26 and a waste heat source 29.
