Second, the design features of the program
      The overall planning of the laboratory, it is necessary to take into account the following requirements: a very wide scope, the need of construction, water, electricity, air conditioning, laboratory professionals and other users to participate in the planning.
• Design Objective: To create a laboratory equipment can ensure that its stable and reliable operation, extending its life, can meet user requirements and the physical and mental health staff in the workplace.
• design: taking full account of the professional relationship between the strict coordination, do good, do not leak, do not touch.
• specific design: the use of advanced technology at home and abroad, selected not only advanced, cost-effective and reasonable environmental protection equipment and materials, integration of the design concept of human nature.

Third, the operational features of constant temperature and humidity laboratory
• constant temperature and humidity laboratory, independent of direct evaporative air-conditioning system of constant temperature and humidity, with a simple, easy adjustment, easy operation and management, energy-saving advantages. In engineering design, based on the accuracy of laboratory temperature and humidity requirements of the system a reasonable choice, as far as possible, a detailed calculation of the room and select the load of constant temperature and humidity to match unit.
• In order to meet the requirements of the accuracy of the indoor temperature and humidity, constant temperature and humidity of the air changes an air-conditioned room, and the light of experience, ± 2 ℃ constant temperature room, ventilation frequency of about 10 ~ 15 times / h; ± 1 ℃ constant temperature room, ventilation frequency of about 15 ~ 20 times / h; ± 0.5 ℃ constant temperature room, ventilation frequency of about> 20 times / h; ± 0.2 ℃ constant temperature room, ventilation frequency of about> 30 times / h;
• is the impact of organizational design airflow room temperature accuracy of one of the main factors in the design of high-precision temperature and humidity of indoor air organizations should consider the principles: a reasonable flow of air distribution, air flow and give full play to the role of cooling or heating; the establishment of a stable uniform temperature field in order to ensure the flow to reach the work area, the average temperature and temperature difference of the work area does not exceed the value of temperature fluctuation permitted; air to reach the work area, the flow rate of 0.25m / s or so. ± 2 ℃ and high-precision ± 1 ℃ constant temperature and humidity laboratory, using the whole orifice plate and local air, the lower uniform wind back, better.
• the construction of laboratories in the constant temperature and humidity, the heat sealing is very critical; heat sealed with a good laboratory to save energy and improve the accuracy of temperature and humidity, reduce operating costs and so on.
