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. This increases the load on the single-package air conditioner to maintain space conditions. In order to bring fresh air in, the indoor air has to “leak” out of the conditioned space. 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. The air-to-air heat exchanger may use the energy trapped on one side of the heat exchanger to be released to the opposite side of the heat exchanger.

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 also include outputting a control signal to a second electronic expansion valve to open and thereby permit refrigerant to flow through a reheat coil.

SYSTEMS AND METHODS FOR MONITORING MAKEUP WATER FOR AUTOMATED LEAK DETECTION
The present disclosure is directed to systems and methods for automatically detecting a leak of a closed loop hydronic boiler system having a makeup water inlet line. The system may include a fluid flow sensor configured to sense fluid flow through the makeup water inlet line, and optionally a pressure sensor and/or a water chemistry sensor. In addition, the system may include a processor configured to detect positive movement of makeup water through the makeup water inlet line indicative of a leak of the hydronic boiler system based on the measured fluid flow, and cause a display to display information indicative of the leak upon detection of positive movement of makeup water through the makeup water inlet line. In some embodiments, the processor further may automatically adjust operations of the hydronic boiler system responsive to detection of the leak.

SYSTEMS AND METHODS FOR HEAT PUMP SYSTEMS WITH DEMAND RESPONSE AND/OR REDUCED POWER CONSUMPTION
Systems and methods are provided for heat pump systems, including water heaters and/or pool heaters, which are capable of communication with one or more utility devices and adjusting operation of the heat pump based on power reduction requests received from the utility devices. For example, a utility company may request a decrease of energy consumption from a device at peak times. The heat pump may include a utility communication port, which may be a CTA-2045 port or may be compliant with any other standardized demand response protocol. The heat pump control system may determine whether or not to reduce power consumption based on the request and may further decide how to adjust operation of the heat pump to comply with the request for decreased energy consumption.

The present disclosure provides a device and a method for detecting leak in a tankless water heater. According to the present disclosure, a leak detection device is disposed on a base of the tankless water heater. The leak detection device includes a leak sensor and at least one absorption arm extending from the leak sensor. The absorption arm wicks water and transports the wicked water towards the leak sensor. The leak sensor generates a signal indicative of leakage in the tankless water heater, in response to sensing wetness.

HEAT PUMP POOL WATER HEATER SYSTEMS AND METHODS THERETO
The disclosed technology includes systems and methods for operating a pool water heating system. The pool water heating system can include a heat pump, a supplemental heat source, a water temperature sensor, and a controller. The controller can be configured to receive water temperature data and, in response to determining that the temperature of the water is less than a threshold temperature, output a control signal to activate the heat pump. The controller can further determine an expected heating time that can be indicative of an amount of time required for the temperature of the water to be greater than or equal to the threshold temperature. The controller can also generate a heating schedule based at least in part on the expected heat time and a predetermined time of use. The heating schedule can be indicative of a heat pump operation time and a supplemental heat source operation time.
