This additional water is provided through a circulating waterway system OR a water tank. The circulating water system OR water tank needs to be designed as part of the unit. 3.6 Single-duct unit An air conditioner whose condensing system performs heat exchange of air, which is taken from the space, room, or area containing the equipment, meanwhile discharges the air outside the space, room, or area through ducts. 3.7 Double-duct unit An air conditioner whose condensing system performs heat exchange of air, which is taken through duct, from outside the space, room, or area containing the equipment, meanwhile discharges the air outside the space, room, or area through ducts. 3.8 Heat pump A cooling system which, by switching the direction of refrigerant operation of the cooling system, absorbs heat from the low-temperature air and releases heat to the room, THEREBY heating up the indoor air. It may also include air circulation, purification devices, humidification and ventilation devices. 3.9 Electric heating device used for heating The electric heating device, which uses only electric heating methods for heating; as well as the electric heating device, which uses temperature Energy efficiency ratio (EER) Under rated conditions and specified conditions, the ratio of the cooling capacity to the effective input power 1), when the air conditioner is in cooling operation. Its value is expressed in W/W. 3.16 Coefficient of performance (COP) Under rated operating conditions (high temperature) and specified conditions, the ratio of heating capacity to effective input power 1), when the air conditioner performs heat pump heating operation. The value is expressed in W/W. 3.17 Indoor discharge air-flow The air volume delivered to the sealed space, room or area per unit time, when the ventilation gate and exhaust gate (if any) of the air conditioner used to exchange indoor and outdoor air are completely closed, under the rated cooling operation conditions. It is in the unit of cubic meters per seconds (or cubic meters per hour) [m3/s (or m3/h)]. 3.18 Room-type calorimeter A test device, which is composed of two adjacent rooms with a partition wall in between. One room is used as the indoor side, whilst the other is used as the outdoor side. Each room is equipped with air conditioning equipment. The cooling capacity, heat capacity, water capacity can be measured and controlled, which are used to balance the cooling capacity and dehumidification capacity of the tested air conditioner on the indoor side, as well as humidification capacity and heating capacity on the outdoor side. 1) The effective input power refers to the average electric power input into the air conditioner per unit time. These include: ① Input power for compressor operation and defrosting input power (except additional electric heating devices which are not used for defrosting); ② Input power for all control and safety devices; ③ Input power for the heat exchange transmission device (fan, pump, etc.). 5.1.1 The air conditioner shall meet the requirements of this standard and GB 4706.32. It shall be manufactured in accordance with the drawings and technical documents, which are approved by the prescribed procedures. 5.1.2 The appearance of the plating of the components and materials of the air conditioner shall be good. The outdoor part shall have good weather resistance. 5.1.3 The thermal insulation layer shall have good thermal insulation performance and flame retardancy; meanwhile it shall be free from toxicity and odor. 5.1.4 For the material of the pressure parts of the cooling system of the air conditioner, it will, under the action of refrigerant, lubricating oil and other mixtures, not be subject to deterioration AND ensure the normal operation of the whole machine. 5.1.5 The installation of the parts of the air conditioner shall be firm and reliable. Between pipe and pipe OR between pipe and part, there shall be not rubbing or collision with each other. 5.1.6 For the parts, structure and materials of the air conditioner, they should be made of parts, product structures and materials that can be used as renewable resources. 5.1.7 The special functions of the air conditioner (such as antibacterial, negative ion refreshing functions, etc.) shall meet the requirements of relevant national regulations and relevant standards. 5.1.8 For the electromagnetic compatibility of the air conditioner, it shall meet the requirements of relevant national regulations and relevant standards. 5.1.9 For all raw materials, auxiliary production materials, packaging materials used by the air conditioner, they must meet the relevant national environmental protection requirements. 5.1.10 The exhaust air of the air conditioner shall not interfere with the temperature and humidity of the air, which is sucked in by the suction port. The air exhaust and suction shall not cause a short circuit of air flow. 5.1.11 See Appendix A for the special requirements of additional water-cooling air conditioners. 5.2 Performance requirements 5.2.1 Sealing performance of cooling system Under normal refrigerant charge, when using a leak detector which has a does not reset, BUT it resets within not more than 30 min after shutdown, it will continue to run for 1 hour. 5.2.7.4 For a manually reset overload protector, if it trips within the first 5 min, it shall be reset forcibly after 10 min of tripping; meanwhile it shall be able to operate continuously for another 1 h. 5.2.8 Cooling at minimum operation When tested according to 6.8, during the 4 hours operation of the air conditioner after the 10 min start-up period, the safety device shall not trip; the frosting area on the windward surface of the indoor side evaporator shall not be greater than 50% of the windward area of the evaporator. Note 1: An automatic resettable protector, that automatically controls the on and off of the compressor to prevent freezing, is not regarded as a safety device. Note 2: When the frosting area on the windward surface of the evaporator is not easy to see, it can be judged by the air volume (not less than 25% of the initial air volume). 5.2.9 Condensation When tested according to 6.9, the air conditioner shall meet the following requirements: a) Condensation on the outer surface of the box shall not drip; b) Indoor air supply shall not carry water droplets. 5.2.10 Condensate removal capacity When tested according to 6.10, the air conditioner shall have the ability to remove condensed water. There shall be no water spilling or blowing out of the air conditioner on the indoor side, so as not to wet the conditioned environment in the sealed space, room or area. 5.2.11 Heating of heat pump at maximum operation 5.2.11.1 When tested according to 6.11, the parts of the air conditioner shall not be damaged; the air conditioner shall be able to operate normally. 5.2.11.2 During the 1 h continuous operation of the air condit.......
