Lab Air Conditioning System Setup
Different laboratories have different requirements for parameters such as temperature, humidity, pressure and cleanliness, and the airflow between different laboratories cannot be cross-contaminated, and the airflow in the experimental area cannot flow to the office area, etc. Therefore, the laboratory building air-conditioning system The requirements are more complex than those of ordinary buildings, and can be divided into decentralized air-conditioning systems, centralized air-conditioning systems and semi-centralized air-conditioning systems according to the setting of processing equipment. Each laboratory of the decentralized air conditioning system adopts independent air conditioners. Common air conditioners include ceiling air conditioners, wall-mounted air conditioners, cabinet air conditioners, etc. The advantages of decentralized air conditioning systems are easy installation, flexible use, convenient management, and laboratory. There is little mutual interference between them, it can be controlled individually, and the maintenance is simple. The disadvantage is that there is no fresh air system, there are many outdoor units of the air conditioner, and the distance between the outdoor unit and the indoor unit cannot be too far. Ordinary laboratories without special pressure difference or cleanliness requirements between laboratories are often used in laboratory construction projects with low investment and small scale.
The semi-centralized air-conditioning system uses multiple air-conditioning units, and separates the areas that have different requirements for the air environment in the experimental building. At the same time, the frequency conversion control system is used to change the energy consumption according to the change of the area of u200bu200buse, so as to achieve the purpose of energy saving ; Semi-centralized air-conditioning system combines the advantages of decentralized air-conditioning system and centralized air-conditioning system, and is widely used in experimental buildings. The clean laboratory is a fully enclosed environment. Through the primary, middle and high efficiency filters of the air-conditioning supply and return air system, the air in the indoor environment is continuously circulated and filtered to ensure that the concentration of suspended particles in the air is controlled to a certain concentration; clean The main parameters that need to be controlled in the laboratory are: the number of dust particles, the number of colonies, the number of air changes, temperature, humidity, pressure difference, illuminance and noise, etc.; common clean laboratories include cell culture room, animal room, plant laboratory, etc., According to the needs of the experiment, there are different requirements for the cleanliness of the environment, temperature, humidity and the working time of the air conditioner. In order to achieve the purpose of energy saving, it is necessary to configure an independent air conditioner unit for rooms that work continuously, such as animal breeding rooms and cultivation rooms. and backup power. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for laboratories, clean laboratories, and microbiology laboratories.
The general laboratory air-conditioning system is a laboratory air-conditioning system that has no special requirements for cleanliness. It is generally designed for comfort air-conditioning. The general requirements for the appropriate temperature in summer are 18-28℃, and the general requirements for humidity are 16-22℃ in winter. It is 30%-70%. In order to ensure that the airflow in the laboratory does not pollute the surrounding public areas, generally maintain a slight negative pressure relative to the public areas. For rooms with experimental conditions or requirements for experimental instruments, it is required to maintain constant temperature and humidity. For example, for precision instruments such as prism spectrometers, the requirements for temperature and humidity are higher. Since the refractive index of prisms varies with temperature, when the temperature fluctuates greatly, it can be used. The measurement accuracy of the wavelength is significantly affected, so the prism spectrometer has strict environmental requirements. Generally, the temperature of the prism spectrometer laboratory is required to be 20 °C ± 5 °C, and the relative humidity is 65% ± 5%. For physical and chemical laboratories equipped with local exhaust equipment such as fume hoods, in order to achieve the purpose of energy saving, in addition to the use of variable air volume system control in the ventilation system, it is also necessary to set up a fresh air supply system for the air conditioning system to avoid excessive air in the laboratory. When the temperature difference between indoor and outdoor is large, it is necessary to perform cold heat treatment on the supplementary air to meet the air supply requirements of fresh air supplementary air.
