V. Description of the invention (1) The present invention relates to a T / East air-conditioning system that can provide the co-construction of multiple evaporator units through co-construction to enable multiple groups of evaporators in different stratospheres or stratospheres. The unit can be combined with the main unit to form a unit, so as to improve the utilization rate of the main unit and reduce the total installation capacity of the main unit and the refrigeration and air-conditioning system occupying space. As shown in the first figure, the store R is a typical occasion where both cold beam and refrigerating equipment (such as Al, A2, A3 freezing and refrigerating cabinets) and air-conditioning equipment are installed at the same time. The refrigeration and refrigerating cabinet evaporator units 1 2, 2 and 3 2 in cabinets Ai, A2 and A3 are matched with a main unit ii, 2 1 and 3 1 on the outdoor side; each of the same air-conditioning evaporation unit 42, 52 Hosts 41 and 5 1 are also matched, so this configuration has the following shortcomings in energy use: 1 · During peak power usage, each host 1 1, 21, 31, 4 1, 51 due to increased load, the probability of each host starting at the same time The relative increase causes high instantaneous power demand and is prone to overload. Not only does it increase the power demand, but it also affects the service life of the host due to the high frequency of the host on and off. 2 · Excessive host configuration not only increases the initial cost, but also consumes a lot of space. Especially in the prime location of the mall, there is no extra space to provide too many hosts. Therefore, the host is mostly placed in the corridor, which not only hinders the passage of pedestrians, but also Obstructive outlook. 3 · Freezing, refrigerating and air-conditioning equipment operates separately. The energy between the two is not only unable to support each other. In the peak time of power consumption, it is often the peak period for the demand for refrigeration, refrigerating and air-conditioning capabilities, but during the off-peak hours, On the contrary, the peak demand for their cold-beam air-conditioning capacity is at the peak of the two;

487796 V. Description of the invention (2) Energy demand gaps such as adjusting equipment because of its low configuration utilization rate and operating efficiency are not in line with the creators of this case, and the creation (or stratospheric) setting is used to reduce the overall host settings to reduce the gap. Large changes require energy 'to resolve the technical means, or the use of frozen air-conditioning systems by multiple groups of Tienan hosts in the stratosphere. The purpose of this creation is to reduce the rate of different temperature layers or this large method. · The effective operation of the source is based on the characteristics of the ability and occupation of the cold preparation co-construction. The sharp and off-peak solution solves the problem of the evaporator and reduces the probability. The type of use is very large. • The space used for the questionnaires and festivals is a combination of square and space for cold storage. The off-peak demand configuration group can be used with the host. The traditional space is used. The cooling or type is improved, which has moderated the bottleneck of the time period, and the lack of it. The host has a total capacity of cold, and the cold, cold, and air are installed on the machine. The shortcomings of the refrigerated air conditioner and the air conditioner are added. The purpose of this paper is to provide a combination of different stratospheres for the purpose of combining and occupying to study the utilization of different stratospheres, peak energy needs and peak periods. The cold space is a combination of stratospheres in the same stratosphere. The cold beam air-conditioning system and the occupied space are more energy-efficient. The total setting capacity of the map host is shown below. For example, please refer to the main connector L connector unit 6 1 6 Each branch pipe 2 and 6 3 in the second figure provides a kind of cold; East, cold reduction, cooling or empty multiple evaporator units can be co-constructed with the host to improve the utilization of the host, reduce the interval, and resolve sharp peaks.
