<p>As discussed herein, a first aspect of the present invention provides a high- efficiency heat pump that includes a frame, as well as a first circuit, a first compressor (146A), a condenser heat exchanger (144), a first electronic expansion valve (148A), an evaporator heat exchanger (142), and a controller. The first circuit, the first compressor, the condenser heat exchanger, the first electronic expansion valve, and the evaporator heat exchanger can be supported by the frame. The first compressor, the condenser heat exchanger, the first electronic expansion valve, and the evaporator heat exchanger can be connected to the first circuit. The controller can be in electronic communication with the first electronic expansion valve, and the controller can be configured to control operation of the first electronic expansion valve.</p> |
