There is provided a method and an apparatus for controlling the temperature of a plurality of rooms having mutually different and varying heat requirements, among which rooms at least one normally has a cooling requirement. The common input air flow to the rooms passes a heat exchanger and is cooled to the requisite temperature for the room having a cooling requirement, while the separate input air flows to the respective rooms are afterheated by means of after heating banks, one for each room, to the desired temperature. The heat exchanger is, or is connected to, an evaporator in a refrigerator (heat pump) the condenser of which is located in the common output airflow from the rooms. The heating banks are heat supplied by part of the condensation heat of the refrigerant vapor. When the cooling requirement for the room having the lowest heat input requirement is replaced by a heating requirement, the heat exchanger is switched to function as a condenser in the refrigerator circuit and the condenser is switched to function as an evaporator in the refrigerator, while the heating banks remain as condenser units.

A method for regulating the temperature of a plurality of rooms having mutually differing and varying heating requirements, among which rooms there is normally a cooling requirement, said method comprising: (a) providing a common input airflow for said rooms; (b) contacting said common input airflow

A method for regulating the temperature of a plurality of rooms having mutually differing and varying heating requirements, among which rooms there is normally a cooling requirement, said method comprising: (a) providing a common input airflow for said rooms; (b) contacting said common input airflow with a cyclically evaporated, compressed, and condensed refrigerant in a first heat-exchange zone to transfer a portion of the heat of condensation of the refrigerant to said common input airflow to impart to said common input airflow a heat content corresponding to the requirement of that room having the lowest heat requirement per supplied unit volume of air; (c) dividing said common input airflow into individual air flows to the respective room; (d) contacting each of said individual airflows in separate second heat-exchange zones with said refrigerant to transfer further portions of the heat of condensation of said refrigerAnt to afterheat, each of said individual airflows to the extent required for the respective rooms; (e) flowing said refrigerant from said second heat-exchange zones to a third heat-exchange zone; (f) providing a common exhaust airflow from said rooms; and (g) contacting said common exhaust airflow in said third heat-exchange zone with said refrigerant to transfer the remainder of the heat of condensation to said common exhaust airflow.
