Preassembled type primary and secondary ring assembly and system applied to floor heating hydraulic system

Abstract

The invention relates to the technical field of floor heating, in particular to a preassembled type primary and secondary ring assembly and system applied to a floor heating hydraulic system. The assembly comprises a primary ring and a secondary ring. The primary ring is composed of an air separator, a front pipeline and a rear pipeline, wherein the two pipelines are connected with the air separator. The secondary ring comprises a water inlet circuit, a water outlet circuit and a circulating pump. The preassembled type primary and secondary ring assembly and system are characterized in that the water inlet circuit and the water outlet circuit of the secondary ring are connected with the pipelines of the primary ring through two tee valves, and the center distance between the two tee valves is four times no larger than the diameter of each pipeline of the primary ring. Hydraulic separation is achieved through loops which are mutually connected and provided with a pair of tee joints, and the distance between two tee joint centers is four times no larger than the diameter of each pipeline of the primary ring circuit. The two tee joints are close as much as possible, so that the differential pressure between the starting point and the terminal point of the secondary circuit is reduced and close to zero. The preassembled type primary and secondary ring assembly and system applied to the floor heating hydraulic system can greatly reduce energy consumption.

Description

[0001] technical field [0002] The invention relates to the technical field of floor heating, in particular to a pre-installed primary and secondary ring assembly and system applied to a floor heating hydraulic system. [0003] Background technique [0004] At present, gas-fired wall-hung boilers are generally used as the heat source of the radiant pipe network in the floor heating market. The heat energy generated by burning natural gas is used to supply hot water to the floor heating pipe network to achieve the purpose of radiant heating. The circulation pump configured for the wall-hung boiler is for the purpose of satisfying the output of hot water. It is impossible and unnecessary to meet the hydraulic circulation power requirements of buildings with different areas. However, in the design and construction of floor heating, it is common for wall-hung boilers to be directly connected to the water separator of the floor heating pipe network, regardless of the size of th...

AI Technical Summary

Problems solved by technology

[0008] 3. The "most unfavorable end", in the area farthest from the main circulation pump, usually does not get enough pressure and flow

[0009] 4. "Local pressure too high"

[0010] 5. The system is unstable, the heating quality of the floor heating is poor, and the energy consumption is high

Due to the above 1~4, the energy transmission of the system cannot meet the needs of each area, and the inlet water temperature must be increased to make the indoor temperature of the area with weak hydraulic power of the system meet the requirements. In this case, the energy supply of other areas is too much. High indoor temperature, energy loss

[0011] 6. Using imported devices in the market for floor heating systems can partially solve the above problems, but the cost is too high and it is not suitable for large-scale application
