Heat pump type heating and cooling source system

Claim 1

A heat pump type heating and cooling source system comprising a primary refrigerant medium circulating circuit utilizing the latent heat of the refrigerant medium, a secondary medium circulating circuit arranged for heat exchange relation with said primary medium circulating circuit and including a utility unit for heating and cooling purposes and at least one heat collecting and radiating member in panel form connected in said primary refrigerant medium circulating circuit, said heat collecting and radiating member being disposed outdoors substantially normal to the horizontal and capable of absorbing heat through solar radiation and from the atmosphere and capable of discharging heat to the atmosphere, the said primary refrigerant medium circulating in said system for winter heating purposes in the said member at an evaporating temperature of from about -10° C. to 20° C. when the cold ambient air is above -10° C. whereby said primary refrigerating medium absorbs solar radiation and heat from the atmosphere and the said primary refrigerant medium circulating in said system for summer cooling purposes at a condensing temperature of from 30° C. to 60° C. when the air temperature is up to about 30° C. whereby said primary refrigerating medium discharges heat through said member to the atmosphere, the said primary refrigerant medium constituting essentially the sole fluid means in the system for absorbing heat from and releasing heat to the outdoors.
