Abstract: An energy efficient heat pump for a heating, ventilation, and air conditioning (HVAC) system includes a vapor compression circuit, a heat exchanger of the vapor compression circuit configured to place a working fluid in a heat exchange relationship with an air flow directed across the heat exchanger, and a valve system of the vapor compression circuit. The valve system is adjustable between a first configuration and a second configuration, the heat pump is configured to operate in a cooling mode with the valve system in the first configuration and in a heating mode with the valve system in the second configuration, and the valve system is configured to direct the working fluid into the heat exchanger to place the working fluid in a counterflow heat transfer arrangement with the air flow in the first configuration and in the second configuration.

The valve system is adjustable between a first configuration and a second configuration, the heat pump is configured to operate in a cooling mode with the valve system in the first configuration, the heat pump is configured to operate in a heating mode with the valve system in the second configuration, and the valve system is configured to direct the working fluid into the first heat exchanger to place the working fluid in a counterflow heat transfer arrangement with the first air flow directed across the first heat exchanger in the first configuration and in the second configuration.
