The vertical attachment position of the warning line on the side surface may determine a ratio of vapor to liquid refrigerant in the flash tank. The warning line may prevent overcharging during the active charging process by an operator (e.g., an HVAC technician, etc.). For example, once the warning system triggers, the operator would stop charging and may or may not release a little bit of refrigerant to achieve an ideally charged system.

To mitigate these impacts, a barometric pressure sensor may be used to measure the atmospheric pressure at any given time and may provide this data to the controller. The controller may then adjust the rate at which gas and/or air is provided within the heating appliance to reduce such inefficiencies.

A heat exchanger for an air conditioner unit is provided. With a conventional single-package air conditioner unit, fresh air mixed with the return air is the outside air.

Thus, the energy spent to cool or heat the “leaking” air is lost, resulting in potential inefficiencies. To resolve these inefficiencies of conventional VTACs, a heat exchanger is provided between the indoor and outdoor sections of the VTAC. In this configuration, a fan may be used to move outdoor air through the heat exchanger to exhaust air while simultaneously using another fan to move indoor air across the heat exchanger to supply air.

If the current temperature is less than or equal to the low threshold temperature, the controller can determine whether a capacity of the HVAC unit at the end of the heating cycle is greater than a threshold capacity and adjust a response setting of the thermostat by a predetermined adjustment amount.

The disclosed technology includes systems and methods for controlling an air conditioning system. The method of controlling the air conditioning system can include receiving air temperature data from an air temperature sensor and determining that the air conditioning system should operate in a reheat mode based on the air temperature being less than a threshold air temperature. The method can include outputting a control signal to a first electronic expansion valve to close and thereby prevent refrigerant to flow through an outdoor condenser coil. The method can also include outputting a control signal to a second electronic expansion valve to open and thereby permit refrigerant to flow through a reheat coil.
