Technical field
The utility model relates to the system that heat supply network of a kind of central heating carries out the ladder heat exchange by the heating system difference, belongs to heating heating technology field.
Background technology
At present, heat supply network of central heating system is transported to thermal substation with heat from thermal source, carries the backheat source to accomplish once circulation through the heat exchanger heat exchange.The problem that exists is: though the heating of gas sheet and floor, fan coil heating system are temperature required different, one time the heat supply network heat is not pressed the utilization of heating temperature demand ladder, wastes energy.
The utility model content
The purpose of the utility model provides heat supply network of a kind of central heating carries out the ladder heat exchange by the heating system difference system; It is different to temperature requirements that the heat of a heat supply network conveying is pressed heating system; Adopt the ladder heat exchange; Improve a heat supply network and carry heat, energy-saving and cost-reducing, solve the problems referred to above that background technology exists.
The technical scheme of the utility model is: heat supply network of central heating carries out the ladder heat exchange by the heating system difference system; Comprise heat supply network feed pipe, heat supply network return pipe, radiator heating heat-exchange device, floor heating heat exchanger; Radiator heating heat-exchange device and floor heating heat exchanger arranged in series; Radiator heating heat-exchange device connects a heat supply network feed pipe, and the floor heating heat exchanger connects a heat supply network return pipe.
Because the temperature requirements of radiator heating heat-exchange device and floor heating heat exchanger differs about 20 ℃; The hot water of a heat supply network of the utility model carries out heat exchange for earlier radiator heating heat-exchange device; Not defeated backheat source of heat supply network backwater after the heat exchange; Import close floor heating heat exchanger and carry out heat exchange, defeated again backheat source behind the secondary heat exchange.
Radiator heating heat-exchange device is connected secondary heat supply network water supply valve, secondary heat supply network backwater valve respectively with the floor heating heat exchanger.
The backwater of radiator heating heat-exchange device is connected with a heat supply network return pipe with valve through pipeline, and radiator heating heat-exchange device can use separately as required.The floor heating heat exchanger supplies water and is connected with a heat supply network feed pipe with valve through pipeline, and the floor heating heat exchanger also can use separately as required; In addition, because each heating system area of heat-supply service is different, the heat demand of radiator heating heat-exchange device and floor heating heat exchanger does not match, if heat is not enough, can be replenished by a heat supply network through opening pipe valve.
Because secondary heat exchange need supply back certain pressure reduction, and is closely effective apart from thermal source, the valve controllable flow amount on the pipeline of the additional heat supply network heat of secondary heat exchange can adopt pressure regulator valve.In addition, it is consistent that gas radiator heating heat-exchange device, floor heating heat exchanger, heat supply network water return pipeline and additional heat pipeline inner fluid flow to, and heat is many can be failed back from former road through the former water return pipeline valves of unlatching.
The good effect of the utility model is: at heat supply network caliber delivery temperature, a flow, have no under the situation of change; Improve one time the heat supply network transfer heat; Save the initial station and carry electric weight, the part heat of secondary heat exchange to reduce once circulation, reduced the conveying heat loss; Economize on resources, reduce heat cost.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
In an embodiment; Heat supply network of central heating carries out the ladder heat exchange by the heating system difference system; Comprise heat supply network feed pipe 1, heat supply network return pipe 2, radiator heating heat-exchange device 3, floor heating heat exchanger 14; Radiator heating heat-exchange device and floor heating heat exchanger arranged in series, radiator heating heat-exchange device connects a heat supply network feed pipe, and the floor heating heat exchanger connects a heat supply network return pipe.Because the temperature requirements of radiator heating heat-exchange device and floor heating heat exchanger differs about 20 ℃; The hot water of a heat supply network of the utility model carries out heat exchange for earlier radiator heating heat-exchange device; Not defeated backheat source of heat supply network backwater after the heat exchange; Import close floor heating heat exchanger and carry out heat exchange, defeated again backheat source behind the secondary heat exchange.
Radiator heating heat-exchange device is connected secondary heat supply network water supply valve 7 and 15, secondary heat supply network backwater valve 8 and 16 respectively with the floor heating heat exchanger.
The backwater of radiator heating heat-exchange device is connected with a heat supply network return pipe with valve 6 through pipeline, and radiator heating heat-exchange device can use separately as required.The floor heating heat exchanger supplies water and is connected with a heat supply network feed pipe with valve 10 through pipeline, and the floor heating heat exchanger also can use separately as required.
The course of work:
1. radiator heating heat-exchange device and floor heating heat exchanger independent operating is separately opened the 4.5.6.7.8 valve, the normal heat supply running of radiator heating heat-exchange device heat-exchange system; Open the 10.12.13.15.16 valve, the normal heat supply running of floor heating heat exchanger heat-exchange system.
2. according to radiator heating heat-exchange device and floor heating heat exchanger to the different operation method heat supplies of taking the ladder heat exchange of heat supply network temperature requirements.At first Open valve 9 of ladder heat exchange mode operation is switched in two former heat-supplying mode operations of heating system, and radiator heating heat-exchange device backwater gets into the heat exchange of floor heating heat exchanger.
Valve-off 6. cuts off radiator heating heat-exchange device water delivery loop.
Valve-off 10 cuts off a heat supply network water supply of floor heating heat exchanger import, takes the operation of ladder heat exchange mode.
If floor heating heat exchanger heat supply temperature is too high, Open valve 6 reduces entering floor heating heat exchanger heat.
If radiator heating heat-exchange device and floor heating heat exchanger heat do not match, but Open valve 11 additional heat transfer to heating quality and require temperature.
