METHOD FOR MANAGING A REFRIGERANT CHARGE IN A MULTI-PURPOSE HVAC SYSTEM

摘要

A method for managing a refrigerant charge in a system for heating water and conditioning an interior space by removing power from an indoor fan for a first duration of time prior to switching at least one valve to configure a second refrigerant circuit for satisfying a water heating demand. A method for managing a refrigerant charge in a system for heating water and conditioning an interior space by removing power from a water pump for a second duration of time prior to switching at least one valve to reconfigure a first refrigerant circuit to satisfy an interior space heating demand.

1. A method for managing a refrigerant charge in a multi-purpose HVAC system including an outdoor unit assembly operably coupled to a water heater module, the water heater module including at least one valve and a pump, the multi-purpose HVAC system further including an indoor unit assembly operably coupled to the water heater module and including a fan, the method comprising the steps of:
(a) operating the at least one valve to configure a first refrigerant circuit; (b) operating the multi-purpose HVAC system in a heating mode to condition an interior space; (c) receiving a first signal at the water heater module; (d) removing power from the fan for a first duration of time; (e) operating the at least one valve to configure a second refrigerant circuit; (f) operating the multi-purpose HVAC system in a water heating mode; (g) receiving a second signal at the water heater module; (h) removing power from the pump for a second duration of time; and (i) operating the at least one valve to reconfigure the first refrigerant circuit.
