摘要： The present invention relates to a method, device and computer program for terminating a defrosting cycle within a refrigerated transport container. The container may include: a transport volume, a cooling unit comprising an evaporator arranged in a cooling space, a return air grid arranged to separate said cooling space from said transport volume, means for sensing temperature indicative of the return air temperature of air returning to said cooling space from said transport volume or the temperature of the return air grid, means for actively heating said evaporator during defrosting cycles, and a processor configured for controlling the duration of said defrosting cycles. The method includes: establishing an indicator(s) indicative of frost and/or ice build-up on said return air grid, and terminating a defrosting cycle when an indicator(s) of frost and/or ice build-up on said return air grid indicates that said return air grid is free of frost and/or ice.

摘要： Disclosed therein are a heat pump system for a vehicle and a method of controlling the heat pump system, which determines that frosting begins on an exterior heat exchanger and carries out a defrosting control if a difference value between outdoor temperature and refrigerant temperature of an outlet side of the exterior heat exchanger is above a frosting decision temperature in a heat pump mode, thereby increasing frost-prevention and defrosting effects and enhancing heating performance and stability of the system because the system recognizes the beginning of frosting on the exterior heat exchanger at a proper time so as to carry out the defrosting control.

摘要： In an air conditioner for a vehicle, a flow speed of air flowing through a first ventilation part of an evaporator is faster than a flow speed of air flowing through a second ventilation part of the evaporator when an intensive air-conditioning operation for a driver seat is operated, with respect to a case where a normal air-conditioning operation is performed. In this case, a correct target evaporator temperature is calculated to be higher by a predetermined temperature than a target evaporator temperature, and a detected temperature detected by an evaporator sensor is approached to the correct target evaporator temperature. Therefore, it can restrict the second ventilation part from being frosted.

摘要： An air conditioner for a vehicle includes: a compressor that compresses a heat exchange medium; an internal heat exchanger that performs heat exchange between the heat exchange medium expelled from the compressor and air for air conditioning introduced inside a vehicle compartment; and an external heat exchanger that performs heat exchange between the heat exchange medium expelled from the internal heat exchanger and external air, wherein the air conditioner for a vehicle calculates a temperature difference between an external air temperature and a discharge port temperature of the external heat exchanger, calculates an average value of the temperature difference, and performs a defrosting operation which melts frost adhered to the external heat exchanger when an amount of change of the average value is equal to or greater than a first predetermined value.

摘要： There is disclosed a vehicle air conditioning device of a heat pump system which delays proceeding of frosting onto an outdoor heat exchanger, thereby eliminating or inhibiting deterioration of a heating capability due to the frosting. The vehicle air conditioning device executes a heating mode in which a controller lets a refrigerant discharged from a compressor 2 radiate heat in a radiator 4, decompresses the refrigerant by which heat has been radiated, and then lets the refrigerant absorb heat in an outdoor heat exchanger 7, and on the basis of a difference TXO=(TXObase−TXO) between a refrigerant evaporation temperature TXObase of the outdoor heat exchanger 7 in non-frosting and a refrigerant evaporation temperature TXO of the outdoor heat exchanger 7, the controller corrects a target subcool degree TGSC that is a target value of a subcool degree of the refrigerant in the radiator 4 in an increasing direction in accordance with increase of the difference ΔTXO.
