Energy-saving measures for clean clean room modular air-conditioning environment

According to the thermal engineering requirements of the air-conditioning environment maintenance structure, enhance the thermal insulation performance of the outer envelope structure, reduce the heat transfer coefficient and the shading coefficient related to the radiative heat transfer through the material, and reduce the air-conditioning load; Relatively speaking, the main factor to be considered is the thermal insulation of the envelope structure, and the heat transfer coefficient requirements are relatively strict; for the air-conditioned buildings in the areas with heat in summer and warm in winter, the insulation of the envelope structure is relatively strict. Heat is the main factor to consider, and there are stricter requirements for the shading coefficient of external windows. For cold areas and areas with hot summer and cold winter, both thermal insulation and heat insulation need to be considered. Combined with the air-conditioning building sub-items, in strict accordance with the air-conditioning design standards and specifications, carry out air-conditioning load calculation and statistics, reasonably select energy solutions and equipment; rationally select air treatment plans and equipment; rationally choose and implement air-conditioning systems, etc., and pay attention to energy saving in all aspects; Reasonably choose the air distribution scheme, and select and arrange the air supply and return air outlets.

The annual energy consumption of air-conditioned buildings is mainly composed of air-conditioning cooling and heating energy consumption, lighting energy consumption, and other living energy consumption. Among them, air-conditioning function and heating energy consumption account for a considerable proportion. The energy consumption accounts for 50%-60% of the energy consumption of the whole building. Among the energy consumption of air conditioners, the energy consumption caused by the heat transfer of the envelope structure accounts for 20%-50%, and the energy consumption required for the fresh air treatment of the air conditioners accounts for 30%-40%. Other energy consumption such as transportation accounts for 10%-20%. The energy-saving measures for air-conditioning environment are mainly adopted: in newly-built projects, start from the design source, carefully grasp the first level of energy-saving technology, and carefully follow the current 'Heating Ventilation and Air Conditioning Design Specifications' and The indicators and requirements of 'relevant energy-saving design standardsIt is also one of the fundamental ways to improve the utilization rate of primary energy and one of the measures to strengthen the security of power supply. Distributed co-generation of cooling, heating and power includes: regional co-generation of cooling, heating and power, and co-generation of cooling, heating and power in buildings. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and dust-free workshops.

According to the actual situation of the project, rationally calculate and determine the fresh air volume and fresh air ratio, and reasonably reduce the energy consumption of the control fresh air; the air conditioning system can supply the cooling capacity or heat of the air conditioner in each clean room modular or terminal according to the requirements of use, so as to prevent the parameters of each area from being changed. Out of control; the stratified air conditioning technology for tall and large spaces forms an air layer with relatively obvious differences between the upper and lower parameters, and the air parameters at the bottom meet the design requirements. Relying on the horizontal jet to block the air circulation up and down, the energy consumption area of u200bu200bthe air conditioner for cooling and heating is reduced, and energy saving is achieved. For some buildings that also need to provide air-conditioning cold water in winter, the cooling tower can be used to directly provide air-conditioning cold water, which can reduce the running time of the chiller and achieve good energy-saving effect. Determine the water supply parameters and select the cooling tower, and the cooling tower should be reviewed and calculated according to the cooling conditions in winter.

However, CUSTOM SOLUTION SERVICES isn't the only producer in domestic, and many people feel that SUZHOU PHARMA MACHINERY CO.,LTD.'s service leaves much to be desired in terms of functionality and design.
