A heating, ventilation, and/or air conditioning (HVAC) system, includes a housing having a wall with an exterior surface configured to be exposed to an ambient environment. The HVAC system further includes a first heat exchanger disposed within the housing and forming part of a refrigerant circuit of the HVAC system and a second heat exchanger disposed within the housing and forming part of the refrigerant circuit, in which the second heat exchanger includes a coil coupled to the wall, such that the coil and the wall are configured to transfer heat between the ambient environment and refrigerant passing through the second heat exchanger.

Auxiliary heat exchanger for HVAC system

A heating, ventilation, and air conditioning (HVAC) system includes a reheat valve configured to receive a refrigerant flow and regulate division of the refrigerant flow provided to a reheat coil and a condenser. The HVAC system also includes a condenser fan configured to draw a flow of outdoor air across the condenser and a controller communicatively coupled to the reheat valve and the condenser fan. The controller is configured to monitor a position of the reheat valve and to control operation of the condenser fan based on a correspondence between the position of the reheat valve and a threshold degree of opening.

Systems and methods for reheat control of an HVAC system

An energy efficient heat pump for a heating, ventilation, and air conditioning (HVAC) system includes a vapor compression circuit, a heat exchanger of the vapor compression circuit configured to place a working fluid in a heat exchange relationship with an air flow directed across the heat exchanger, and a conduit system of the vapor compression circuit. The conduit system of the vapor compression circuit is configured to direct the working fluid into the heat exchanger and to receive the working fluid from the heat exchanger, wherein the conduit system is configured to direct the working fluid into the heat exchanger to place the working fluid in a counterflow arrangement with the air flow directed across the heat exchanger in a cooling mode of the heat pump and in a heating mode of the heat pump.
