Variable type room air conditioner SEER of regional

Temperature variation of a certain room air conditioning operation frequency,[link widoczny dla zalogowanych], so that the room air conditioner cooling capacity and indoor load balance, this time the room with the room air conditioner cooling capacity is equal to the load, the load when the room changes, room operating frequency of air conditioner, cooling capacity and input power changes are followed in order to maintain a constant temperature room set to reduce the fixed-frequency type room air conditioner frequent downtime caused by the opening stop losses and improve the comfort of the room n. From 2 can be seen in the analysis, frequency-type room air conditioner energy efficiency and its application in areas closely related to the temperature zone. Therefore, in order to achieve better energy savings, it is necessary for different parts of the production of room air conditioners. While improving energy efficiency under constant frequency EER is also very necessary. For different areas, improvement of the existing room air conditioner SEER measures: 1) the use of research-mm internal thread is not high efficient copper tube gear, multi-fold evaporator technology, evaporator fin fin with unequal height, increasing wing film density, increasing the heat transfer area, the fin surface of special treatment, and less surface deposition of pollutants, and less resistance, increased evaporation temperature, thereby enhancing the efficiency of room air conditioners. 2) will be considered in the design condenser condensate spraying the surface of the condenser to reduce the condensing temperature, thus improving energy efficiency. 3) the use of the outdoor unit or the ECM variable speed high efficiency PSC blower motor. Full use of inverter technology, in part to increase fan speed under load, reducing the temperature difference, lower condensing temperature, increase the instantaneous EER, thereby increasing the energy efficiency throughout the season. 4) or high-efficiency scroll compressor rotor in order to improve the energy efficiency of room air conditioners. 5) The efficient use of environmentally friendly refrigerants, improve circulation efficiency and achieve energy saving. Improve the energy efficiency of a one in 50, while the relative humidity in the larger Yangtze River region, such as Shanghai, Wuhan and other places,[link widoczny dla zalogowanych], the bottom of the outdoor heat exchanger design considerations need to focus on, so conditions in the dehumidification and defrosting running well, dehumidification and defrosting effect is obvious. At the same time for the cooling season, relatively mild weather conditions in areas manufacturers should strive to improve the room air conditioner EER at part load in order to make the seasonal energy efficiency ratio improved. 5 Conclusion As China's demand for room air conditioners in the production and the rapid development of the evaluation of room air conditioner has a single standard conditions from the energy efficiency ratio (Ⅱ) to the more scientific SEER (S Ⅱ) changes. In particular, the frequency is currently in the ascendant type room air conditioner of the evaluation criteria have not formally introduced. Analysis of the SEER GB7725 draft pending formula and made changes. At the same time the temperature zones based on the division of our country, gives the map of temperature belts, collected eight cities in China for nearly 3o years of meteorological data, compared to the standard with the nominal temperature, calculated using the frequency-type rooms in eight cities SEER air conditioner, can be seen from the results, the division of the temperature with greater impact on the SEER, so manufacturers to produce products, an important parameter. In reducing energy consumption and the urgent demand of energy,[link widoczny dla zalogowanych], raising energy efficiency room air conditioner is essential, and manufacturers to improve product energy efficiency at the same time in different parts of the climatic conditions for production of different products in order to achieve better energy efficiency effect.
