A complete water and ground heating system can not be separated from four parts: heat source, control, pipeline and thermal insulation. The wall-hanging stove is the heat source center of the ground heating, which meets the heat demand of the whole system; the above-ground parts such as insulation layer, reflective film, heating pipeline and backfill layer ensure the insulation function of the system; and the normal operation of the water collector and temperature controller maintenance system.
Gas wall-mounted furnace is a process of incineration after premixing gas and air, heating daily hot water through heat exchange system, and heating air at the end of heat dissipation for heating or heating. Wall-hanging furnaces have different types of general furnaces and condensation furnaces according to their thermal efficiency.
Condensation wall hanging furnace uses condensation skills to absorb heat from high temperature flue gas and latent heat of steam, so that thermal efficiency is greatly improved. The rated thermal efficiency of wall-hanging furnace is 88-94% and that of condensing wall-hanging furnace is 99-109%. The condensation wall-hanging furnace has high incineration efficiency and can save energy consumption. Otherwise, the heat recovery of flue gas during the incineration process can further reduce gas consumption, and the energy consumption expenditure will be reduced accordingly. Because the condensation furnace uses a new mixing heat incineration and a large pipeline water system, compared with the traditional wall-hanging furnace, there is no need to worry about scale treatment.
The water supply temperature of the geothermal system is lower, generally in the range of 40 ~50. For general wall-mounted furnaces, when the outdoor temperature is lower than - 3 C, the system requirement temperature of wall-mounted furnaces will be lower than the dew point temperature of flue gas 57 C. Generally, wall-mounted furnaces must go through a water mixing device to reduce the water supply temperature and improve the return water temperature, in order to prevent the general wall-mounted furnaces from being lower than the dew point temperature for a long time, and to meet the water supply temperature required by the water heating system. The condensation wall hanging furnace can provide hot water directly to the water heating system without adding mixing water center.
The water collector can not only adjust the temperature, but also undertake the task of connecting the wall-mounted furnace and the heat dissipation end. First of all, it includes the main catchment pipe, exhaust and drainage devices, branch valves and connecting accessories, which are equivalent to the heart of the geothermal system. The hot water of the whole geothermal system is evenly distributed to each branch by the water distributor. After circulating in the geothermal pipe, it gathers together and then distributes under the action of the water pump, so as to ensure the safe and normal operation of the whole heating system.
The geothermal water collector can play a very good role in assisting the temperature control chamber heating. After controlling the opening and closing status of the flow regulating valve, the hot water in the pipeline can be controlled, and then the indoor temperature can be adjusted. When designing the large-scale heating system, water supply and return pipes will be installed in different regions. Each water pipe corresponds to the way of the water diverter. When there is no one in an area for a long time, users can choose which water diverter to turn off, so as to achieve the purpose of sub-room heating. 。
After accurately detecting the indoor temperature, the temperature signal measured is transmitted to the inside of the thermostat to compare with the temperature set by our users until the indoor temperature is automatically adjusted to the ambitious temperature set by us.
Floor heating belongs to concealed engineering, and the service life of pipes should be synchronized with the housing. Once problems arise, the loss may be much higher than the value of pipes themselves. Therefore, the long-term temperature, pressure and reliability of pipes for floor heating are high. Ground heating pipeline is a carrier of low temperature hot water circulation, and both the main pipe and coil pipe belong to the pipeline system. There are many kinds of heating pipes, such as PE-RT pipes, PEX pipes, PB pipes and so on.
Auxiliary material is also an important detail of the floor heating device. Energy saving and heat preservation of the floor heating system are inseparable from the floor heating auxiliary material. The geothermal insulation system is composed of basic data such as insulation board, reflective film, boundary insulation strip, expansion joint and so on.
The thermal insulation extrusion board is laid at the bottom of the heating system, which can prevent the heat from transferring downward and reduce the invalid heat loss of the structural layer. When choosing insulation board, attention should be paid to the comprehensive consideration of environmental protection, compression resistance, water absorption and heat conduction system. For long-term bearing of the above-ground load, the insulation board should improve its compressive strength as far as possible, select materials that satisfy the carrying capacity to prevent the above-ground settlement and cracking; select materials with high humidity and low moisture absorption rate; and choose insulation board with small thermal conductivity as far as possible to ensure good thermal insulation and insulation effect, and then better reduce the daily operating expenses of the floor heating.
Geothermal reflective film is placed in the center of insulation board and heating body as a kind of data of heat reflection. A good reflecting film can reflect the radiated heat of the heater to the upper layer, effectively reduce the heat loss downward, improve the heating rate, and achieve energy-saving effect of 10% - 20%. Reflectivity and corrosion resistance are the basic criteria for evaluating the quality of reflective coatings. The higher the reflectivity, the better the effect of heat reflection. The lower the reflectance, the worse the heat reflection.
Water heating construction must enter the site after the completion of hydropower decoration. When installing water heating, we should harmonize the construction period with the decoration company in advance to prevent cross-construction, so as to avoid the disorder of the construction site. Good products should also be matched with good construction technology to ensure the ultimate heating effect.
