    恒温恒湿实验室采用直接蒸发式独立恒温恒湿空调系统,具有系统简单、调节方便、操作管理方便、节能等优点。在工程设计中,应根据实验室温湿度精度的要求合理选择系统,尽可能详细地进行房间负荷计算,选择匹配的恒温恒湿机组。
    The constant temperature and humidity laboratory adopts the direct evaporation independent constant temperature and humidity air conditioning system, which has the advantages of simple system, convenient adjustment, convenient operation and management, energy saving and so on. In engineering design, the system should be reasonably selected according to the requirements of laboratory temperature and humidity accuracy, room load calculation should be carried out as detailed as possible, and matching constant temperature and humidity units should be selected.
    为了满足室内恒温恒湿精度的要求,恒温恒湿空调房的换风频率较大。根据经验,±2℃恒温恒湿温室的换风频率约为10 ~ 15次/h。±1℃恒定温室,通风约15 ~ 20次/h;在±0.5℃恒温温室中,换气次数约为>20次/h;在±0.2℃的恒定温室中,空气变化约为>30次/h。
    In order to meet the requirement of indoor constant temperature and humidity accuracy, constant temperature and humidity air-conditioning room has a higher frequency of air exchange. According to experience, the frequency of air exchange in (+2 C) constant temperature and humidity greenhouse is about 10-15 times/h. The ventilation rate is 15-20 times/h in (+1 C) constant greenhouse, 20 times/h in (+0.5 C) constant temperature greenhouse, and more than 30 times/h in (+0.2 C) constant greenhouse.
    送风设计也是影响恒温温室精度的主要因素之一,在高精度室内恒温恒湿送风设计中应考虑的原则是:合理的送风过程,充分发挥送风的冷却或加热作用;建立稳定均匀的温度场,保证气流到达工作区域时,平均温度与工作区域温度之差不超过允许的温度波动值。当气流到达工作区域时,流速约为0.25m/s。高精度恒温恒湿实验室±2℃、±1℃采用全孔板和部分孔板,下部送风和回风均匀,效果较好。
    Air supply design is also one of the main factors affecting the accuracy of thermostat greenhouse. In the design of high precision indoor air supply with constant temperature and humidity, the following principles should be considered: reasonable air supply process, giving full play to the cooling or heating effect of air supply; establishing stable and uniform temperature field to ensure the average temperature and working area temperature when air reaches the working area The difference of degrees does not exceed the allowable fluctuation of temperature. When the airflow reaches the working area, the velocity is about 0.25m/s. The whole orifice plate and part orifice plate are used in the high precision constant temperature and humidity laboratory. The lower air supply and return air are uniform and the effect is good.
    在恒温恒湿实验室的建设中,其绝缘密封性也十分重要。本实验室保温、密封性好,具有节能、提高温湿度精度、降低运行成本的优点。
    In the construction of constant temperature and humidity laboratory, its insulation sealing is also very important. The laboratory has the advantages of heat preservation, good sealing, energy saving, improving temperature and humidity accuracy and reducing operation cost.
    选择恒温恒湿精密空调的主要因素
    Main factors for selecting constant temperature and humidity precision air conditioning
    A.控制精度:建立实验室的目的是建立一个符合技术标准的检验和测试环境。因此,设备的控制精度能否满足我们的要求,是选择精密空调的首要因素。建议高精度恒温恒湿实验室采用最先进的精密空调,采用完整的模拟量控制技术,保证高精度的同时更稳定的温湿度。
    实验室装修
    A. Control Accuracy: The purpose of establishing a laboratory is to establish an inspection and testing environment that meets the technical standards. Therefore, whether the control accuracy of the equipment can meet our requirements is the primary factor in choosing precision air conditioning. It is suggested that the most advanced precision air conditioning and complete analog control technology should be adopted in the high precision constant temperature and humidity laboratory to ensure high accuracy and more stable temperature and humidity.
    B.可靠性:恒温恒湿实验室是生产企业产品质量检验控制和流通领域商品质量检验的基础设施。在试验过程中,应保证实验室的正常使用。因此,产品成熟度是精密空调选型的关键因素。
    B. Reliability: Constant temperature and humidity laboratory is the infrastructure of product quality inspection and control in production enterprises and commodity quality inspection in circulation field. During the test, the normal use of the laboratory should be ensured. Therefore, product maturity is a key factor in the selection of precision air conditioning.
    C,节能、环保、节能和环境保护是可持续发展的首要的社会作为一个整体,选择新技术的恒温恒湿精密空调与传统常数由大功率加热加湿制冷除湿补偿控制方法相比节能50%以上,与传统的封装机组相比,同时安装电力负荷要求可降低50%以上,大大降低了设备运行成本。
    C. Energy saving, environmental protection, energy saving and environmental protection are the most important aspects of sustainable development of society as a whole. Selecting new technology of constant temperature and humidity precision air conditioning can save more than 50% energy compared with traditional constant high-power heating and humidification refrigeration dehumidification compensation control method. Compared with traditional packaging units, the requirement of installing power load at the same time can be reduced. More than 50% lower, greatly reducing the cost of equipment operation.
    D.操作方便:恒温恒湿实验室的操作人员大多不熟悉暖通空调及设备,因此有必要确保空调机组的操作界面友好易懂,不需要专门培训。同时,机组设备需要简单的日常维护和管理,不需要专业人员;机组设备体积小,以占实验室面积尽可能小。
    D. Easy to operate: Most operators in constant temperature and humidity laboratories are not familiar with HVAC and equipment, so it is necessary to ensure that the operation interface of air conditioning units is friendly and easy to understand, and no special training is required. At the same time, the unit equipment needs simple daily maintenance and management, and no professional personnel; the unit equipment is small in size, so as to occupy the laboratory area as small as possible.
