Radiator connection method affects the introduction of heat, in fact, many heating users do not know, when the radiator system in the piping, the way it will affect the pipe, radiator heat, so the radiator pipe system must pay attention.
One, radiator control
Each radiator should be installed in the return valve. The inlet valve has manual and automatic adjustment valves. Automatic control valve, also known as radiator temperature control valve, the user can set the room temperature through it, when the room temperature increases, the valve opening decreases, the valve opening increases when the temperature decreases, automatically maintain the room temperature constant. At the same time, effective use of solar radiant heat and heat (free heat) generated by electric appliances, personnel, etc., saves users the cost of heating.
Second, the choice of pipeline
The tubes that can be used are: galvanized steel pipe, crosslinked polyethylene pipe, PP-R pipe, aluminum-plastic composite pipe, stainless steel pipe, copper pipe, and plasticized copper pipe. For the independent heating system, the copper pipe and the plasticized copper pipe are very reliable connection methods through welding or press-fitting joints. The use of plastic material pipe must consider the influence of oxygen penetration and pipe aging on the heating system. Whichever pipe is chosen to solve the problem of thermal expansion and the reliability of the connection is very important.
Third, the cloth way
(a) Radiator connection method for surface mounted pipes:
1. Single-tube series, this method is simple and saves pipe. However, the radiator (especially at the end) must be increased accordingly, and the temperature of each room cannot be individually adjusted and closed, the system resistance is large, and the boiler outlet water temperature is required to be high.
2. The single-tube and cross-over tubes are connected in series to solve the problem of separate control of the radiators, but the above other problems still exist, and the increased cost of the radiator by-pass devices.
3. Double pipes are connected in parallel. This connection method is relatively complicated, but it is very convenient for the regulation of each group of radiators. Usually the trunk pipe is arranged on the top of the room, and each radiator is connected to the horizontal pipe by a vertical branch pipe, and the system is easy to adjust and overhaul. The problem is that there are too many pipes in the room and the decoration is affected. The air in the system is not easy to discharge, and it is easy to produce pipe flow noise.
(b) Radiator radiator connection:
1. Diffusion type (octopus type) connection, with separate radiators connected to each set of radiators. Each set of radiators is an independent pipe. There is no joint under the ground, usually cross-linked polyethylene pipe or aluminum-plastic composite pipe. . The problem is that the slot is too wide and the tubing consumes a lot and is not suitable for all occasions.
2. Double-pipe parallel connection, the suitable pipe is cross-linked polyethylene pipe, aluminum-plastic composite pipe, copper pipe and plastic-clad copper pipe. The advantage is that all pipes are buried in burial, indoor pipe pipe is simple, each radiator is easy to control, and heating The system is very beautiful after installation. The problem is that the process of pipe connection is better. It is necessary to ensure that the joint does not leak water, the ground is to be grooved, and the construction is relatively complicated.
Fourth, insulation
For general Lighting systems, insulation is not required in general. If there are pipes that are partially enclosed in the kitchen, they can be insulated with PE or rubber-plastic pipes. The dark pipe system is preferably made of polyurethane foam insulation.
