Abstract
Contemporaneous hybrid heating may be provided by a heat pump, including: an indoor heat exchanger located in or in communication with the conditioned environment; an outdoor heat exchanger located in or in communication with the outdoor environment, wherein the outdoor heat exchanger is in fluid communication with the indoor heat exchanger via a refrigerant circuit; a fueled heater; and a controller, configured to, when the system is operating in a hybrid heating mode, activate both of the heat pump and the fueled heater at a given time based on an air rise temperature measured across the indoor heat exchanger.
Claims20
A system for conditioning air in a conditioned environment inside a structure with an outdoor environment outside the structure being non-conditioned, comprising:
- a heat pump, including:
- an indoor heat exchanger located in or in communication with the conditioned environment;
- an outdoor heat exchanger located in or in communication with the outdoor environment, wherein the outdoor heat exchanger is in fluid communication with the indoor heat exchanger via a refrigerant circuit;
- a fueled heater;
- and
- a controller, configured to, when the system is operating in a hybrid heating mode, activate both of the heat pump and the fueled heater at a given time based on an air rise temperature measured across the indoor heat exchanger.
A method for conditioning air inside a structure, comprising:
- activating, by a controller, a heat pump to heat a conditioned environment inside the structure;
- detecting, using a sensor, an air rise temperature across an indoor heat exchanger of the heat pump located in or in communication with the conditioned environment;
- determining, using the controller, whether the air rise temperature is below a triggering threshold;
- and
- when the air rise temperature is below the triggering threshold, activating, by the controller, a fueled heater to heat the conditioned environment contemporaneously with the heat pump at a given time.
A computer readable medium including instructions, that when executed by a processor, cause the processor to perform operations including:
- activating, by a controller, a heat pump to heat a conditioned environment;
- detecting, using a sensor, an air rise temperature across a heat exchanger of the heat pump located in or in communication with the conditioned environment;
- determining, using the controller, whether the air rise temperature is below a triggering threshold;
- and
- when the air rise temperature is below the triggering threshold, activating, by the controller, a fueled heater to heat the conditioned environment at the same time as the heat pump at a given time.
