[Abstract]:The performance test of air conditioning products is one of the most energy-consuming links in the whole production and manufacturing process. How to reduce the energy consumption of the performance test link, It is one of the key points to reduce the energy consumption in the air conditioning manufacturing industry. This paper analyzes the design methods of the traditional performance test bench at home and abroad, and classifies the energy consumption of the conventional performance test bench. The performance experiment of large air-cooled chilled water (heat pump) unit built by Thaling Air conditioning system (China) Co., Ltd was studied. The performance experiment of the unit was completed, and the energy saving characteristics of the test bench was verified. The main research contents of this paper include: 1) analyzing the rule of energy consumption of the conventional performance test bench, including the power input of the unit to be tested, and providing a reference for the system energy saving design of the same type of test bench in the industry. In order to maintain the constant water temperature and water flow rate, the energy input to the test bench system and the energy input to the test bed system to maintain the temperature and humidity working conditions of the machine being tested in the test room are also found. The last two items are found. Both the refrigeration and heating conditions of the unit under test are opposite, and the input energy of one item is the heat when the input energy is the cooling quantity. Therefore, from the point of view of energy transfer and conservation, these two terms can complement each other. The energy consumption of the conventional refrigeration unit performance test bench is calculated in detail. It is found that the conventional performance test bench is carrying out the performance test. The energy consumption of the test bench is more than 2.59 times of the refrigerating capacity of the tested unit, and the energy balance and control optimization are used to realize the energy-saving design of the performance test bench. This paper includes the temperature and flow control of water system and flow control of water system. The principle of environmental temperature control of energy saving test bench and the principle of environmental humidity control of energy saving test bench. The temperature control of constant temperature water tank on energy saving test bench is expounded. The realization method and control principle of the performance test bench are designed. The design and calculation of air handling box, pipeline system, auxiliary chiller, compression condenser, steam, cooling tower, water pump, plate heat exchanger and so on have been completed. The development of measuring system and testing software of humidity, power and flow rate shows that the energy consumption of the test bench is about 1.12 times of the cooling capacity of the machine under test. The tests were carried out on the AHRI standard 100% and 25%, and the results show that the design is reasonable and energy saving.
