Description

A kind of prepackage type major/minor loop assembly and system that is applied to floor heating Hydraulic Power System

Technical field

The present invention relates to floor heating technical field, particularly relate to a kind of prepackage type major/minor loop assembly and system that is applied to floor heating Hydraulic Power System.

Background technology

Floor heating at present generally adopts the thermal source of burnt gas wall hanging furnace as radiation pipe network on market, produces heat energy by gas-firing, supplies with floor heating pipe network hot water, reaches the object of radiant heating.The circulating pump of wall-hung boiler configuration is to meet hot water to be output as object, it can not, the also unnecessary Hydraulic Circulation power demand that meets different area building.But in floor heating design and construction, ubiquity wall-hung boiler directly connects floor heating pipe network water knockout drum, no matter area of heat-supply service size.

There is in various degree following drawback in the Hydraulic Power System of designing in traditional hydraulics theoretical foundation:

1. " rob water ", when a system comprises 2 or above district's (water knockout drum), the circulating pump of one of them loop can easily obtain the flow more than rated value, and the flow of the pump that makes other in identical power output situation is less than metered flow value.

2. " short circulation ", the flow direction of circulation fluid is always towards the low one end of pressure, and circulation fluid can be by getting back to water inlet end compared with shortcut line, rather than arrive the district that reach.

3. " least favorable end ", from main circulation pump district farthest, can not get enough pressure and flow conventionally.

4. " local pressure is too high ".Because the waterpower of system does not separate, the mutual interference of local formation waterpower phase, or main circulation pump unlatching, district's circulating pump quits work, and mineralization pressure is too high, configure pressure relief valve.

5. system fluctuation of service, the heating quality of floor heating is poor, and energy consumption is high.Due to above-mentioned 1 ~ 4, system capacity is carried the demand that can not meet each district, must improve inflow temperature, just can make the indoor temperature in the district of system waterpower weakness reach requirement, in this case, the Power supply in other district is too much, cause indoor temperature higher, energy loss.

Adopt the device of existing market upper inlet for ground heating system, can partly address the above problem, still, cost is too high, is unsuitable for large-scale promotion application.

Summary of the invention

The present invention is according to accurate hydraulic P/S manifold (Primary/Secondart Piping) principle, design a kind of prepackage type major/minor loop assembly and system that is applied to floor heating Hydraulic Power System, thereby reach the object that improves floor heating heating quality, significantly reduces heating energy consumption.

Technical scheme of the present invention is as follows:

A kind of prepackage type major/minor loop assembly that is applied to floor heating Hydraulic Power System, described assembly comprises main ring and secondary ring, described main ring is made up of front and back two pipelines of air separator and connection air separator, and described secondary ring comprises into water loop, goes out water loop and circulating pump, it is characterized in that:

The water inlet loop of described secondary ring with go out water loop and be connected with the pipeline of main ring by two triple valves;

Centre distance between described two triple valves is not more than 4 times of main ring caliber.

Further, the water inlet loop of described secondary ring with go out thermometer is installed in water loop.

The floor heating Hydraulic Power System that major/minor loop assembly described in claim 1 is installed, is characterized in that:

The front and back pipeline of described main ring connects gas fired-boiler, the water inlet loop of described secondary ring and go out water loop and be connected to respectively water knockout drum.

Further, described main ring is connected with water replanishing device by air separator.

Beneficial effect of the present invention is:

The present invention uses to several water knockout drums from single water knockout drum, as long as the loop of corresponding minimizing pump or increase pump has following beneficial effect:

1, the present invention is simple in structure, easy for installation, cost is low.The present invention has adopted the structure of major/minor loop, simple in structure, and saving resource and human cost only need be directly installed according to design when installation.

2, the present invention does not have " robbing water ", " short circulation ", " least favorable end " and " local pressure is too high ".System waterpower not only separates, and balance.

3, the realization that waterpower of the present invention separates is to be completed by the interconnective loop with a pair of threeway.Guarantee that two threeways are close as far as possible, to reduce the pressure reduction between time loop starting point and terminal, make it close to zero.Distance between two threeway centers, is no more than 4 times of major loop caliber.

4, in main ring of the present invention, increase air separator, thereby make heat exchange more effective.

5, whole Hydraulic Power System operates steadily, without pressure relief valve.

6, the present invention can form mixed water according to flow set, and boiler leaving water temperature can be reduced to the required inflow temperature of water knockout drum by mixed water.Can use to the greatest extent lower inflow temperature.

7, the present invention can significantly reduce energy consumption.
