摘要： An air conditioner may include a heat exchanger having a first cooling coil and a second cooling coil inclined toward each other, an inlet formed between a lower end of the first cooling coil and a lower end of the second cooling coil to allow air to pass through, an inside air duct through which air introduced to the inlet flows, an air supply duct through which the air passing through the heat exchanger flows, a fan causing air passing through the heat exchanger to flow, and a temperature sensor sensing a temperature of the air introduced into the heat exchanger. The heat exchanger includes a plate positioned between the first cooling coil and the second cooling coil. The plate may have a sensor insertion hole into which the temperature sensing device is inserted. By measuring the temperature of the air introduced into the heat exchanger, more accurate control information may be provided.

摘要： Systems and methods are disclosed that calibrate a defrost threshold used to determine when a heating, ventilating, and air conditioning (HVAC) system enters a defrost mode, and, more particularly, determine frost temperature differences used to determine the defrost threshold when the HVAC system is in a stable condition. A frost temperature difference is a difference between an outdoor ambient temperature and a refrigerant temperature. The HVAC system determines that it is in the stable condition by determining that a standard deviation of a current frost temperature difference from a previous frost temperature difference is below a standard deviation threshold. When the HVAC system is in the stable condition, the frost temperature differences are determined, and the defrost threshold is determined from the frost temperature differences.

摘要： An HVACR fan and heater assembly accounts for the cyclonic flow produced by centrifugal blowers by placing a heater vertically and biased towards a side of a fan cabinet in order to increase and balance airflow through the heater, eliminating hot spots and fire risk and improving heater efficiency. A blockoff in the fan cabinet forces airflow within the cabinet to move through the heater. The positioning of the heater may vary depending on the direction of rotation of the centrifugal blower. The fan and heater assembly may further include baffles to direct the airflow from the centrifugal blower.
