Abstract
Abstract The combined heat pump system and ice making system includes a heat pump system used for normal heating purposes. The heat pump system is augmented with an ice making system wherein ice is formed on the system evaporator. This ice making improves the operational efficiency of the heat pump system during cold or sunless periods. Additionally, the resulting ice is collected and stored for use as ice.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
200 words
A combined heat pump system and ice making system, said heat pump system including a compressor, evaporator, and condenser, all connected together in operative relationship, said evaporator comprising a first plate element having at least one surface portion for absorbing sunrays and converting such rays to heat energy, tubular structure in heat exchange relationship with said first plate element for conduction of heat energy from the first plate element to the tubular structure, fluid refrigerant circulated in said heat pump system, and means for deploying water on said first plate element at a preselected evaporator temperature to form ice thereon, said means for deploying water on said first plate element adapted to deploy water on the underside of said first plate element with said first plate element being oriented so that one surface portion defines an underside, and a second plate element having opening means therein for passage of water provided between said means for deploying water on said first plate element whereby ice formed on the first plate element may drop downwardly onto said second plate element for transportation away from said first plate element, and storage means to receive ice which is transported on said second plate element.
Claim 2
Dependent Claim
200 words
A combined heat pump system and ice making system, said heat pump system including a compressor, evaporator, and condenser, all connected together in operative relationship, said evaporator comprising a first plate element having at least one surface portion for absorbing sunrays and converting such rays to heat energy, tubular structure in heat exchange relationship with said first plate element for conduction of heat energy from the first plate element to the tubular structure, fluid refrigerant circulated in said heat pump system, and means for deploying water on said first plate element at a preselected evaporator temperature to form ice thereon, said means for deploying water on said first plate element adapted to deploy water on the underside of said first plate element with said first plate element being oriented so that one surface portion defines an underside, and a second plate element having opening means therein for passage of water provided between said means for deploying water on said first plate element whereby ice formed on the first plate element may drop downwardly onto said second plate element for transportation away from said first plate element, and storage means to receive ice which is transported on said second plate element.
Claim 3
Dependent Claim
52 words
A combined heat pump system and ice making system as in claim 1, further characterized in that said means for deploying water on said plate element comprise a plurality of spaced apart nozzles positioned to spray water onto the plate element, said nozzles being connected to a source of water under pressure.
Claim 4
Dependent Claim
37 words
A combined heat pump system and ice making system as in claim 1, further characterized in the provision of electrical control means for actuating said means for deploying water on said plate element at a preselected temperature.
