ABSTRACT:This paper fan-coil performance tests on the design, because system fan-coil unit as a central air-conditioning system with end equipment, installation is convenient, flexible, and other characteristics, energy regulation is widely suitable for hotels, restaurants, etc. In the room of air-conditioning systems In recent years, with fan coil units types of diversification, its use occasions more extensive. Since the 19th century in China in the early 70s begin production since fan coil units, whether quantity or the quality had the very big enhancement, its main performance index has no gap with foreign products. But, fan coil units product performance specification differences exist, product quality problems such as the good and bad are intermingled. Some equipment can not meet the design and application requirements, industry management department is difficult to fan coil units to make quantitative judgment, quality of social repercussions strongly. Therefore, we conducted fan-coil performance test system design.
Because of the fan-coil laboratory studies involving intellectual property and many other factors, and open the relevant data published less. Although foreign research institutions with relatively advanced testing techniques involved, but the cost is higher; Domestic researches in working stability time, accuracy and reliability and there are certain foreign gap. In intense market competition, economic globalization today, laboratory evaluation and said the unity of science and technology method has become the urgent demand of the exchange and international trade, it makes the measurement and various countries in the results obtained than each other, can recognize each other and consensus.
According to the domestic and foreign relevant standards, fan-coil performance testing system has carried on the thorough exploration. The construction of this system involving process, control and computer automatic test, and other professionals. Technical difficulties, and control parameters measurement range, high accuracy requirements, test condition complex.
