FIELD: heating.SUBSTANCE: invention relates to a temperature control system, particularly to a mixing chamber for temperature control. It includes a housing through which at least one air flow can pass and in which there installed is at least one filter device through which an air flow can pass; with that, the air flow passes through a valve unit containing at least one valve; with that, the valve unit includes an ambient air influx valve, a recirculation valve and a mixed air influx valve, the control of which is performed depending on a certain parameter, namely depending on ambient temperature, preferably depending on ambient or plenum air temperature; with that, if ambient temperature is below 0°C, a provision is made for pre-heating of a filter by heating of ambient air entering through the ambient air influx valve by the room air that enters through the mixed air influx valve, with that, control of the valve unit is performed so that depending on a certain parameter, namely depending on temperature, air flow passes through one of the filter devices.EFFECT: invention allows reducing power consumption due to a possibility of natural cooling in a wide range of temperatures.8 cl, 6 dwg |
