Abstract: Disclosed herein are air conditioning systems including a refrigerant line configured to transport a refrigerant; a compressor in fluid communication with the suction line; and a controller in communication with a sensor configured to measure a characteristic of the refrigerant line. The compressor can be configured to move the refrigerant through the refrigerant line, and the refrigerant can have a first temperature at the outlet of the compressor. The controller can be configured to receive sensor data from the sensor indicating a current value associated with the characteristic of the refrigerant line; determine, based at least partially on the sensor data, that the characteristic of the refrigerant line is above a predetermined threshold; and output instructions for the compressor to perform one or more corrective actions.

Abstract: The present disclosure relates to a HVAC system operable to use a refrigerant in a refrigerant circuit to heat or cool an indoor space and includes a defrost circuit connected to the refrigerant circuit. The defrost circuit includes a first three-way valve, a defrost line, a defrost passage in an outdoor heat exchanger, and a defrost return line. When the HVAC system is in a defrost mode, a four-way valve is operable to direct the refrigerant flow in a second direction through the outdoor heat exchanger. The first three-way valve is operable to divert some or all of the refrigerant from the refrigerant circuit and through the defrost circuit to defrost the outdoor heat exchanger. The defrost return line returns the diverted refrigerant to the refrigerant circuit upstream of an expansion device and downstream of the indoor heat exchange with respect to the second direction.

Abstract: Vehicle air conditioning device executes the dehumidifying mode in which a controller lets refrigerant discharged from compressor 2 radiate heat in radiator 4, decompresses the refrigerant from which heat has been radiated and then lets the refrigerant absorb heat in heat absorber 9 and outdoor heat exchanger 7, or lets the refrigerant discharged from compressor 2 radiate heat in radiator 4 and outdoor heat exchanger 7, decompresses the refrigerant from which heat has been radiated and then lets the refrigerant absorb heat in heat absorber 9. In the dehumidifying mode, the controller executes simple control to compare a target value of an index that is a basis of control of the outdoor expansion valve with an actual detected value and to change a valve position of the outdoor expansion valve from a magnitude relation between the value in an enlarging direction or a reducing direction as much as a constant value.

Abstract: A refrigeration appliance includes a storage chamber, an evaporator that cools the storage chamber, and a processing unit configured to assign values for the air humidity in the storage chamber and an evaporation temperature of the evaporator to one another, at a given temperature of the storage chamber, under the assumption that the absolute water vapor content of the air of the storage chamber is the same as that of water-vapor-saturated air at the evaporation temperature. This assignment makes it possible on one hand to estimate the relative air humidity in the storage chamber on the basis of the temperatures, and on the other hand to control the air output temperature, at constant temperature in the storage chamber, in order to influence the air humidity therein.

Abstract: A refrigerating and air-conditioning apparatus performs, even during a heating operation under air conditions leading to formation of frost, a defrosting operation while simultaneously continuing the heating operation and improves comfort through heating by securing an appropriate amount of ventilation. A plurality of refrigeration cycles independently performs a heating operation and a defrosting operation. By controlling a ventilation damper of an indoor unit that is to perform a defrosting operation to increase the amount of ventilation, a prior ventilation operation for securing the time-averaged required amount of ventilation including the period in which the defrosting operation is being performed is performed before the defrosting operation, and after the prior ventilation is terminated, the defrosting operation is started.
