此外本文还阐述了系统的分区布置和冷热源的选择。冷热源部分采用室外管网所提供的冷水，冷水系统的工作压力为0.3MPa，热水系统的能源由厂区的锅炉供给，热水系统的定压由厂区的锅炉房保证。并且考虑了有关热回收的问题，空调加热加湿所需要的蒸汽是由锅炉房提供的，供气压力为0.6MPa，蒸汽入口处一次减压至0.4MPa，一部分供给生产供热，一部分减压至0.07~0.1MPa后供空调加湿，减压及供给生产供热，生产供热的凝结水之空调机房后再次回收。此处不做详细的赘述。
本设计内容包括：空调冷热负荷计算；空调系统的确定及论证；送风状态参数及送风量的确定；空气处理设备的选型；冷热源的选择；气流组织计算；水力计算；其他设备的选择；保温、减振和消声等内容。
空调系统设计应用于动物实验室时，更要结合洁净厂房的特点，使之符合风速、温度、湿度、及人的舒适性，有利于实验人员能更好高效的工作。所以充分考虑合理的气流组织、 温湿度及压力控制及节能措施，使设计更合理，更符合国家规范，满足业主要求。
DESIGN SPECIFICATION
The design for the Shanghai Blood Products Co., Ltd. on the 5th animal room air conditioning system design, through the design of interior will provide a comfortable working environment to meet the experimental animal room for cleanliness requirements. As one of important buildings housing animals must pass on experimental animals and their living environment manual control to ensure the accuracy and reliability of the experimental results, so it's air-conditioning system directly affects the level and quality of animal experiments. This design took into account the demand for clean plant, according to the Shanghai region's energy structure and energy situation and the current level of economic development, to meet the human thermal comfort, improve work efficiency of the premise, give full consideration to the entire air conditioning system, energy conservation and For cleanliness maintained.
The building design combined with ordinary air experimental area, feeding areas, walkways and clean workshop as a whole, the construction of single-storey industrial building, total construction area of 992.25m ², roof height of 5.95m. Designed primarily for each regional office and factory air-conditioning design for the laboratory personnel, reared animals provide a comfortable and healthy environment. The design of the various parts of the building according to the structural characteristics and its use, taking full account of the comfort of the indoor environment, industry and energy required for industrial conditions and other aspects of the basis.
The main system partition is based on different functional areas clean plant classification, pided into ordinary air-conditioned rooms Zone K1, K region and ten thousand purification zone. K area using using some fresh air without heat recovery, K1 district DC fresh air, ten thousand purification area is also a new wind system with DC. System is pided into a total of four systems, ordinary air-conditioning system is pided into two kinds, because part of the room air is not polluted some fresh air can be used mixed with return air form; while for ordinary air contamination exists on the use of fresh air room systems. On the other hand purification zone air conditioning in the fresh air unit within the multi-added purification and filtration segment is used in conjunction with activated carbon absorption unit exhaust.
The design of four different fresh air units, respectively, SGT-440 × 3, SGT-500 two kinds of units. Refrigerant parameters 7 ~ 12 ℃ cold water, heat medium parameter is 50/60 ℃ hot water. And with the use of PKJ1-1 and PKJ1-2 and PK1-2 three exhaust fan. New air unit commitment conditioned room cooling load and thermal load, K to some rooms because they do not direct contact with the reagents drugs directly from the ceiling average placement of new wind square diffuser, and in the interval of at least the outlet five meters installed at the return air, making the back Wind through the collection directly after mixing with fresh air by increasing ventilation frequency reaches the plant area cleanliness requirements, so that both can make the plant energy can reach the cleanliness requirements. K experiment in direct contact area of the room, go through the discharge portion of the exhaust air volume units to ensure that the indoor air quality. K1 area of fresh air through a separate clean fresh air handling units, and then through the ceiling into the interior of the diffuser, and exhaust directly through the side under the exhaust, through a separate exhaust air shaft into the activated carbon filter exhaust unit vented to the outdoors. Here is the single barrier environment, so can effectively prevent contamination also facilitate post-cleanup and management. According to the actual use of the building, to ensure that most of the rooms are used at the same time, and the function of the room area clear, so the use of four different new air handling units ensure that the indoor air environment is necessary, so that the air can be prevented cross-infection, nor waste can use the return air. This system has the advantage of centralized heating and cooling and can be unified regulation of air, making the air condition to achieve a uniform standard. And in the end of the venturi valve setting, instead of the conventional VAV BOX more energy in order to effectively control the amount of air to complete. Taking into account the plant part of the room there is the need for uninterrupted operation, the design also considered the choice for standby fan. This is also the need for room partitions. The fan of choice, considering the frequency conversion fan, not only to meet the operating pressure of the room but also to ensure energy needs.
