The application of heating heating system
System part of the additional investment as it increases, electric boilers and heat pump heating system changes in annual operating costs. For electric heat pumps, the system only when the heat units for additional investment is less than l500 dollars lkW (heat),[link widoczny dla zalogowanych], the heating system without heat storage than the economy will be a good time. Under normal circumstances the system is less than the value of additional investment. However, if the accumulator space occupied by the high costs, for example, in prime locations in the urban setting, you can make additional investment surge regenerative system, resulting in heat storage system can improve the overall economy. The electric boiler, as long as the heat regenerative unit for additional investment is less than 49 (30 yuan / kW (heat), heating system without heat storage than the economy would be a good time, this is usually regenerative additional investment will not be greater than this value. Therefore, for electric heat pump heating, heat storage devices are added, the situation should be analyzed according to the specific argument to be decided. The electric boiler heating effect of additional heat storage device is obvious. crucian carp gate 30o1500 ... ...,, ... one - one by one 'one by one' a.. + thermal recovery (regenerative) -. _ electric boiler (1t ~ t + pump - electric boiler handsome 20oo300040oo $ 0oo accumulator 010 surcharge / per.. Figure 6 with the annual operation cost heating system storage Additional changes in the cost of Regenerative Thermal Heater - electric heating,[link widoczny dla zalogowanych], you can achieve through the regenerative power of the load shifting water. However, due to the volume of accumulator large centralized power can only be used for thermal systems, if combined with home heaters, will take up more space room to ask, this is unrealistic. To this end, a heater and a combination of phase change material phase change thermal storage heating equipment of a power radiator made to teach. phase change material heat storage capacity, heat storage, high efficiency, and as the source of low cost electric heaters, which can overcome the lack of hot water heat storage. Table 2 shows that this heating device The non-pressure hot water thermal storage capacity of only about one-eighth of the accumulator. accumulator is a pressure hot water for about one-third. Meanwhile, the initial investment is relatively small. In addition, the phase change storage adjust flexible heat radiators, installed in the heating room, which means that the use, heat or power by the fan throttle control, which can reduce the maximum heating load hours. It can be seen from Figure 5, this heating device has a very good economy, better than the electric and gas boiler heating. At the same time, this heater can reduce the power difference between peak and valley, safe and efficient operation for the power of positive significance. Therefore,[link widoczny dla zalogowanych], the phase change thermal storage electric heater is a kind of good prospects for the development of new phase change thermal storage heating system heaters because power consumption is high, when the room heating load is large, there is the problem the user circuit transformation. 4 Conclusion increasing pollution in the atmosphere, peak power situation continues to widen , urban heating in the form of heating should be selected and run a reasonable way. in ensuring the heating effect, while contributing to environmental protection and power to achieve the overall efficiency of the Sheng big play. in all forms of heating, heating,[link widoczny dla zalogowanych], traditional coal-fired Although the operation of heating boilers, low cost, but will cause a lot of dust and harmful gas emissions, the most serious pollution of the atmosphere, which should be strictly limited use in urban areas. electric heating energy conversion efficiency is low, power consumption, the economy is the worst . it should be strictly controlled use. but start and stop regulating flexible heater, heating load hours to reduce the maximum number of areas in the use of hollow of a tree does not produce environmental pollution, and therefore heating requirements for the short time user, you can choose to consider Heater . electric boiler energy consumption and economic aspects are obviously not as good as other heating systems, should not encourage the use of. the power plant to heat the district heating system has obvious economic advantages. When the full year to ensure sufficient heat load power plant, under the premise priority should be given the use of combined heat and power heating system. gas-fired boilers, although I can be dyed to solve environmental problems in the hollow of a tree a heating means, but running costs are high, gas pipeline construction will increase the initial investment. Therefore, the gas-fired boiler use should be carefully carried out. heat pump as a solution to environmental problems should be an effective way to encourage the climatic conditions or water conditions permit area to be used. the use of heat pump has just started in most areas, pilot projects should be promoted after the accumulation of operating experience application. electric heating devices to increase thermal storage equipment, the peak load shifting can play the role of the grid, but will lead to the initial investment of heating system, energy consumption and increase in area and other issues. in the power differential is widening valley Today, electric thermal storage heating in the application should receive enough attention.
