Abstract
A polymodal heat pump is configured heat domestic water and bidirectionally move heat between ambient air and beneath a ground surface. The polymodal heat pump has a compressor, with a compressor intake and a compressor discharge. A receiver and accumulator are joined to the compressor discharge is connected. A first reversing valve is joined to the receiver and accumulator and the compressor intake. A first coil is joined to the first reversing valve with a second motorized valve. A geothermal heat exchanger is joined to the first reversing valve with a third motorized valve. A second coil is joined to the first reversing valve with a fourth motorized valve. A first electronic expansion valve is joined to the second coil. A second electronic expansion valve is joined to the first coil through the first electronic expansion valve.
