Abstract: 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.

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.

Abstract: An outside air management system in which the air is cooled by a first refrigeration condenser to a temperature either above or somewhat below the dewpoint of the incoming air so as to remove either none of the moisture to be removed, or a significant portion of it. The air then is sent to a desiccant wheel which removes the remainder of the moisture to be extracted. The temperature of the air leaving the wheel is above the desired delivery temperature. Then a heat exchanger and a second condenser remove sensible heat from the heated air leaving the desiccant wheel to bring the air to the desired temperature. Thus, the temperature and humidity are controlled substantially independently of one another. A heat pump embodiment of the invention allows the reversal of the flow of refrigerant in the system, allowing it to be used to either heat or cool.
