Abstract
Described herein is a modular de-superheater and water heater system. The system comprises a refrigerant-to-water (RW) heat exchanger comprising a first coil, and a second coil in thermal communication with each other. A first end of the first coil is connected to a first port of a heat pump and a second end of the first coil is connected to an inlet of an indoor fan coil unit. A first end of the second coil is connected to an outlet of a DHW tank and a second end of the second coil is connected to an inlet of the DHW tank. The system further comprises a solenoid valve connected between an outlet of the fan coil unit and a second port of the heat pump, and an electronic expansion valve connected between the second port of the heat pump and the second end of the first coil.
Claims20
A modular de-superheater and water heater system, the system comprising:
- a refrigerant-to-water (RW) heat exchanger comprising a first coil, and a second coil in thermal communication with the first coil to facilitate heat exchange therebetween,
- wherein a first end of the first coil is configured to be fluidically connected to a first port of a heat pump associated with an outdoor unit and a second end of the first coil is configured to be fluidically connected to an inlet of an indoor fan coil unit associated with an area of interest (AOI), and
- wherein a first end of the second coil is configured to be fluidically connected to an outlet of a domestic hot water (DHW) tank associated with the AOI and a second end of the second coil is configured to be fluidically connected to an inlet of the DHW tank;
- a solenoid valve configured to be fluidically connected between an outlet of the fan coil unit and a second port of the heat pump;
- and
- an electronic expansion valve (EXV) configured to be fluidically connected between the second port of the heat pump and the second end of the first coil of the RW heat exchanger.
