摘要： Systems and methods are provided for controlling an expansion valve of a climate control system evaporator coil. An evaporator coil temperature sensor senses temperature of refrigerant within the evaporator coil near the evaporator coil outlet. A controller determines a control set point based on the refrigerant temperature near the evaporator outlet. The control set point is used to determine a valve opening area to regulate refrigerant flow into the evaporator coil such that temperature of refrigerant at the evaporator coil outlet is within a temperature band having a lower bound within a predetermined range above the liquid-to-vapor transition temperature.

摘要： Provided is an air-conditioning and hot water supply combination system capable of maintaining a high hot water supply capacity and achieving high efficiency even under high-temperature outside air conditions by appropriately controlling the degree of superheat and the degree of subcooling of a heat exchanger. In an air-conditioning and hot water supply combination system, when an evaporating pressure or an evaporating temperature calculated from the evaporating pressure reaches a first predetermined value or higher, the degree of superheat of a refrigerant on a low-pressure gas side of a subcooling heat exchanger or the degree of subcooling of the refrigerant on a high-pressure liquid side of the subcooling heat exchanger is controlled by the opening degree of a low-pressure bypass pressure reducing mechanism, such that the evaporating pressure or the evaporating temperature calculated from the evaporating pressure is less than or equal to the first predetermined value.

摘要： A method for controlling a refrigerant distribution in a vapour compression system, such as a refrigeration system, e.g. an air condition system, comprising at least two evaporators. The refrigerant distribution determines the distribution of the available amount of refrigerant among the evaporators. While monitoring a superheat, SH, at a common outlet for the evaporators, the distribution of refrigerant is modified in such a manner that a mass flow of refrigerant to a first evaporator is altered in a controlled manner. The impact on the monitored SH is then observed, and this is used for deriving information relating to the behaviour of the first evaporator, in the form of a control parameter. This is repeated for each evaporator, and the refrigerant distribution is adjusted on the basis of the control parameters. The impact may be in the form of a significant change in SH. Alternatively, the control parameter may reflect a change in SH occurring as a result of the modification of the distribution of refrigerant.

摘要： The present invention provides a vehicle air-conditioning system in which an air for air-conditioning is cooled at a first evaporator, is heated at a condenser, and is supplied to a vehicle interior in heating operation. The object of the present invention is to suppress a dew condensation at the first evaporator to prevent a freeze of the dew condensation water even if the temperature of the air for air-conditioning introduced from the outside of the vehicle is low. The above object is achieved by disposing a second evaporator between an automated expansion valve to decompress the refrigerant exhausted from a compressor and the first evaporator so as to reduce the absorbed heat at the first evaporator.

摘要： A vapour compression system comprises a compressor, a condenser, an expansion device, e.g. in the form of an expansions valve, and an evaporator arranged along a refrigerant path. A method for operating the vapour compression system comprises the steps of: obtaining a superheat value being representative for the superheat of refrigerant entering the compressor; obtaining a subcooling value being representative for the subcooling of refrigerant entering the expansion device; and operating the expansion device on the basis of the obtained superheat value and on the basis of the obtained subcooling value. The subcooling value is taken into account when operating the expansion device, because variations in the subcooling value have significant influence on the refrigerating capacity of the evaporator at a given opening degree of the expansion device, thereby resulting in a more stable operation of the system. The system may further comprise an internal heat exchanger.
