1. an energy-saving control method for fixed Teat pump boiler radiant floor heating system frequently, is characterized in that determining frequency Teat pump boiler radiant floor heating system and comprises and determine frequency Teat pump boiler (1), storage tank (2), water circulating pump (3), floor hot-water coil pipe (4), control system (5), storage tank temperature sensor (6), room air temperature sensor (7) and outdoor environment temperature sensor (8);

  • The temperature that described storage tank temperature sensor (6) is responded to counts water supply actual temperature T gs, the temperature that room air temperature sensor (7) is responded to counts room actual temperature T ns, the temperature that outdoor environment temperature sensor (8) is responded to counts outdoor environment temperature T w, its Energy Saving Control step is as follows;

    (1) described control system (5) is according to the fixed performance of Teat pump boiler (1) frequently and the thermic load characteristic of heating room, by calculating the water supply accounting temperature T setting up floor gjwith outdoor environment temperature T wbetween functional expression (I);

    (2) room that described control system (5) is set up based on human thermal comfort degree calculates air themperature T njwith outdoor environment temperature T wbetween functional expression (II);

    (3) described control system (5) is with the accounting temperature T that supplies water gj±

    1 DEG C of start-stop control temperature as frequently Teat pump boiler (1) surely, i.e. actual temperature of supply water T gs>

    =T gjwhen+1, fixed Teat pump boiler (1) is frequently out of service, as actual temperature of supply water T gs

    T gjwhen-1, fixed Teat pump boiler (1) frequently restarts operation;

    (4) described control system (5) calculates air themperature T with room nj±

    1 DEG C of start-stop control temperature as water circulating pump (3), i.e. room actual temperature T ns>

    =T njwhen+1, water circulating pump (3) is out of service, as room air temperature T ns

    T njwhen-1, water circulating pump (3) restarts operation.
