Research On The Applied Technology Of Capillary Plane Radiation Air-conditioning

The rapid development of China’s construction industry leads to the sharp rising ofbuilding energy consumption, and air-conditioning energy consumption is the main energyconsumption in the building industry, occupying a large proportion. So the energy savingof air-conditioning is particularly important. At the same time, because of theimprovement of user’s requirements for indoor environment, we need study about thethermal comfort of indoor environment. Based on the requirement of energy saving ofair-conditioning and the improvement of thermal comfort conditions and the capillaryplane radiation air-conditioning as the research object, this paper discussed the energysaving, thermal comfort and its applicability in Qinhuangdao area of capillary planeradiation air-conditioning from omnibearing.According to the literature review about the development of capillary plane radiationair-conditioning technology at home and abroad, to reduce air-conditioning energyconsumption and improve the thermal comfort of air-conditioning room is the mainline inthis kind of air-conditioning system, which belongs to the new technology in the field ofair-conditioning, so there are still few application examples in our country.For the thermal comfort, this paper used Airpak software to establish the3Dsimulation model of air-conditioning room,and employed the numerical simulationmethod to simulate and analyse capillary plane radiation air-conditioning and traditionalair-conditioning system. Through the analysis of indoor air velocity, temperature, air age,PMV, PPD, the comfort of air-conditioning room comprehensively was evaluated.For energy saving, this paper employed the latest achievements of modernthermodynamics-exergy analysis method, and compared with traditional air-conditioning.Then it studied the use of high efficiency and energy saving features of the capillary planeradiation air-conditioning, thus it revealed the capillary plane radiation air-conditioningenergy saving, and more important was its saving qualitative characteristic. At the sametime, because the capillary plane radiation air-conditioning can take advantage of hightemperature cold water and low temperature hot water to meet the demand for hot and cold air-conditioning room in different season, enlarging the utilizing temperature range ofcold energy, which can use more cold energy to replace the traditional energy. So it canhelp to realize the further goal of energy saving in number.As applicable condition, this paper taked Qinhuangdao area as an example, discussedthe applicability of the natural condition of Qinhangdao to the capillary plane radiationair-conditioning system. Taking a villa as an example, we designed capillary planeradiation air-conditioning system and evaluated the system’s initial investment, operatingcost and its technical and economic index.In this paper, it was concluded that capillary plane radiation air-conditioning systemwas effective in improving the indoor environmental comfort and its energy saving featurewas obviously. From the natural cold energy utilization and improvement of the indoorenvironment comfort point of view, this was undoubtedly a air-conditioning technologywith wide application field and bright development prospects.
