<p>TITLE HEAT PUMP INVENTOR Clayton Lemal A heat pump system suitable for northern climates which utilizes a pressure limiting device that reduces pressure and capacity of the system in the cooling mode so as to allow a higher capacity in the heating mode for a given compressor-motor power rating. The pressure limiting device also alleviates problems associated with system reversal, such as for periodic outdoor heat exchanger defrosting.</p> |
