Calculation And Research On Radiator Quantity For Heating Design

Radiator heating system is still the main building heating system in our country. However, during the self-assembling radiator process, decorated engineers, retailers, users and others besides designers sometimes can not predict the concrete quantity of radiators they needed in a room. There is not easy-handling and reliable computing software to meet the need. Moreover, when the quantity of radiators is inappropriate, the energy conservation building will not save energy any more, and result in energy consuming. Therefore, it has a significant meaning to explore easy-computing heating radiator quantity software and develop the research on editing radiator quantity.Fist of all, after simplifying the calculating of heating load amount and radiators quantity properly, and fixing on basic properties properly, we use C++ Builder as the software development environment to develop a simple heating radiator quantity calculating software. The specific example proceeded by the software demonstrated that this software has many merits like compact and friendly interface, easy to manipulate and so on.Secondly, based on the assumption that heat transfer between households is ignored during the steady-state, the thesis calculated the radiator quantity in different regions and different radiator types, and analyzed its influence on indoor temperature. The research demonstrated that: the more radiators there are, the less influence it would take to the indoor temperature after rounding the radiator quantity in the same region; editing column radiator quantity has wee influence on indoor temperature difference, so the editing criteria can be unified; editing the same quantity of the same radiator type has a significant influence on indoor temperature in cold regions.In the end, we analyzed the influence on indoor temperature by editing radiator amount under the condition that heat transfer between households is considered. We can come to a conclusion that: Whether considering the heat transfer between adjacent rooms or not, the influence of editing radiator pieces amount towards indoor temperature has the same regularity, and fluctuation range is basically the same. Higher indoor temperature make editing criteria more flexible. In the same region, the smaller the designed heat transfer takes percentage in the total heat load, the larger the round-off of the radiator pieces amount could be. Considering that the heat transfer between adjacent rooms occurs uncertainty, and it would result in elevate indoor temperature, we edit the radiator pieces amount according to the standard that indoor temperature can not lower than 18℃.The results of this study show that:Without considering heat transfer of neighboring-house, column radiator can truncate different round-off in different regions. The round-off amount would be more than 20 pieces in Harbin; more than 19 pieces in Shenyang; more than 16 pieces in Beijing; and more than 14 pieces in Zhengzhou. When heat transfer between adjacent rooms is considered and 18℃is used as standard temperature, 12 pieces radiators can be rounded off in different regions. Since indoor temperature would be influenced more if panel radiator used 0.2m as a unit, 0.1m is the suggested unit during editing.
