Thermal storage air conditioning system using natural cold air

摘要

PROBLEM TO BE SOLVED: To solve the problem of a prior art system that the structure is intricate, cold heat recovery is low and a countermeasure must be taken against the load of ice. SOLUTION: In the heat storage air conditioning system utilizing natural chill, a water tank 4 is disposed in a thermal insulation chamber 1 constituting an outdoor air introducing section 2 and a discharging section 3, an ice making water supply section 5 is disposed above the water tank 4, a water spray section 6 is disposed above one side of the water tank and a water intake section 7 is disposed on the other side thus constituting a heat source water circulation system 9 extending from the water intake section through a heat exchanging section for air conditioning to a water spray section. Ice making water is supplied from the ice making water supply section into the water tank in winter season, ice is made in the water tank by passing outdoor water of ice point or below through the thermal insulation chamber via the outdoor air introducing section and the discharging section and the ice is preserved in thermally insulated state until cooling season. In the cooling season, ice 17 in the water tank is sprayed with heat source water from the spray section and melted and water is taken in from the intake section and utilized as a cold heat source for air conditioning at the heat exchanging section for air conditioning of the heat source water circulation system.
