Abstract: A dehumidifier for dehumidifying an enclosure is described. The dehumidifier has a desiccant holder for holding a desiccant and a bias mechanism to bias the dehumidifier into a first configuration in which desiccant held by the desiccant holder is exposed to an interior of the enclosure (in order to remove moisture from the enclosure). The dehumidifier also includes a translation means to overcome the bias mechanism such that, when activated, the translation means moves the dehumidifier into a second configuration in which the desiccant is exposed to an atmosphere outside the enclosure (in order to regenerate the desiccant).

The vapour compression system (1) comprises a compressor (2), a heat rejecting heat exchanger (3), a controllable valve (4), a receiver (5), at least one expansion device and at least one evaporator arranged along a refrigerant path having refrigerant flowing therein. The vapour compression system (1) is capable of being operated in a subcritical control regime as well as in a supercritical control regime. The method comprises the steps of measuring a temperature, T GC , of refrigerant leaving the heat rejecting heat exchanger; calculating a pressure reference, P GC,Ref , based on the measured temperature, T GC , and using a calculation formula being applicable to the subcritical control regime as well as to the supercritical control regime; and controlling an opening degree of the controllable valve in order to obtain a pressure of refrigerant leaving the heat rejecting heat exchanger which is equal to the calculated pressure reference, P GC , Ref. Since the calculation formula is applicable to the subcritical control regime as well as to the supercritical control regime, only one calculation formula is necessary, and the vapour compression system (1) can thereby be controlled in a very easy manner.

Abstract: A method for controlling a supply of refrigerant to an evaporator (5) of a vapour compression system (1), such as a refrigeration system, an air condition system or a heat pump, is disclosed. The vapour compression system (1) comprises an evaporator (5), a compressor (2), a condenser (3) and an expansion device (4) arranged in a refrigerant circuit. The method comprises the steps of: Actuating a component, such as an expansion valve (4), a fan or a compressor (2), of the vapour compression system (1) in such a manner that a dry zone in the evaporator (5) is changed; measuring a temperature signal representing a temperature of refrigerant leaving the evaporator (5); analysing the measured temperature signal, e.g. including deriving a rate of change signal; determining a temperature value where a gain of a transfer function between the actuated component and the measured temperature drops from a maximum value to a minimum value, in a decreasing temperature direction; defining the determined temperature value as corresponding to a zero superheat (SH=0) value of refrigerant leaving the evaporator (5), and controlling a supply of refrigerant to the evaporator (5) in accordance with the defined SH=0 temperature value, and on the basis of the measured temperature signal. The method steps may be repeated at certain time intervals in order to provide updated determinations of the SH=0 temperature value. The method allows the SH=0 point to be determined purely on the basis of the measured temperature signal. Subsequently, the supply of refrigerant to the evaporator (5) can be controlled purely on the basis of the measured temperature signal.

Abstract: A method to manufacture a valve using metal injection moulding is disclosed. The valve housing (2) comprises a welding cap (14) for welding the upper part (5) of the valve to the valve housing (2).
