Gas engine driven heat pump system with integrated heat recovery and energy saving subsystems

摘要

A gas heat pump system powered by natural gas, propane or similar gaseous fuelis disclosed. The system uses heat recovery and heat addition to manage efficientheating and cooling cycles. In a cooling cycle excess heat is vented to the atmospherewhile in a heating cycle, excess heat is used to heat a subject structure and toprevent frost from forming on outdoor heat exchangers. A control system monitorsthe system's operation and corrects abnormal operational conditionsor shuts down the system until the system can be manually inspected. The costsof system operation are less than electric systems because of the efficienciesand use of natural gas or propane.
