Abstract: An embodiment of a thermal storage module installable on a climate control system. The thermal storage module is an independent device that can be mountable between an outdoor unit and an indoor unit of the climate control system. The thermal storage module may include a fluid tank, a fluid pump, a heat exchanger for exchanging thermal energy between the working fluid and a refrigerant flow within the refrigerant circuit, an expansion valve and a solenoid valve, and a controller. The fluid pump is activated when the climate control system is operating in a heating mode and a defrost mode and is deactivated when the climate control system is operating in a cooling mode. The operation of the expansion valve and solenoid valve depends on the operation mode (cooling/heating/defrosting) of the main climate control system.

Abstract: Examples of the present disclosure relate to systems and methods for controlling the positioning of a modulating valve of a heat pump based on a discharge temperature setpoint of a compressor during periods of low ambient outdoor temperatures. A supervisory switching controller may determine that the climate control system should use a discharge temperature controller or a superheat controller to control the modulating valve. Upon detection of ambient outdoor temperatures below a minimum threshold and the detection of discharge temperatures of a compressor above a maximum threshold a discharge temperature controller may control the modulating valve. The discharge temperature controller may control the positioning of the modulating valve based on a discharge temperature setpoint and a map-based controller. The map-based controller may map a calculated discharge temperature error to a position of the modulating valve as a function of a calculated superheat value and a measured suction pressure.
