Abstract

1,038,020. Air conditioning; heating and cooling buildings. SVENSKA FLAKTFABRIKEN A.B. Dec. 21, 1964, No. 51927/64. Headings F4V and F4U. In an induction type air conditioning system secondary air is treated in the heat exchangers mounted in the induction units before mixing with primary air and the liquid medium supplied to these heat exchangers is maintained at a temperature common for the whole plant and lower than the temperature of the secondary air, the temperature of the primary air being regulated in dependence on the outdoor conditions. In Fig. 4, 1 designates the heat exchangers within the induction units, 2 a heat exchanger forming part of the central air conditioning plant and 3 pipe lines forming a closed circuit between heat exchangers 1 and 2. 4 and 6 are circulation pumps, pump 6 maintaining through a by-pass line 7 a constant liquid flow through the heat exchanger 2 regardless of the number of heat exchangers 1 being used. During winter, heat is supplied by heated primary air, but in order to eliminate simultaneous cooling by the heat exchangers 1, the heated medium is passed to heat exchanger 2 through which the primary air 5 is taken in. In order to prevent moisture forming on heat exchangers 1 the medium is maintained at a temperature which is above the dew point temperature of the room air by introducing into the circuit a quantity of heated medium from a separate heat source at 8 and withdrawing a corresponding quantity of the medium at 9. In order to maintain, during fluctuations of outdoor air temperature, the medium at a desired temperature quantities of warm or cold medium are added to the circuit, the warm medium added as previously described and the cold medium added at 12 with a corresponding quantity discharged at 13. When the ventilating air 5 is too hot to cool the medium in heat exchanger 2, the medium is maintained at the desired temperature solely by the cold medium supplied at 12, circuit 3a, Fig. 5. If in this case, should the ventilating air also require cooling, a separate cold medium supply line 19 is used regulated by valve 20 which is governed by thermostat 22 located in the air flow 5, the cold medium passing straight to the heat exchanger 2 around circuit 3b. Any warm or cold medium added to the circuit is always added to the circuit immediately after the corresponding quantity has been withdrawn.
