Energy saving measures for clean workshop supporting cold storage environment

When designing and installing the supporting cold storage in the clean pharmaceutical cleanroom, the location of the cold storage should be selected. In the design and construction of the cold storage, the thermal insulation design of the envelope structure should be done first to prevent cold bridges; the load calculation of the cold storage should be done according to the design standards and specifications. , Select energy-saving host and auxiliary equipment; in operation and use, it is necessary to control and adjust the load changes of the cold storage to achieve energy saving in the operation and management of the cold storage, strengthen the maintenance and management of the cold storage facilities, establish a sound inspection system, and strictly prevent water leakage and electricity leakage. The refrigeration room or refrigeration unit should be arranged close to the cold room with the largest cooling load, and have good natural ventilation conditions. The cooling capacity of the cold storage needs to be transported to different rooms through management, and the room with a larger cooling load also has a higher demand for cooling capacity. Therefore, reducing the length of the transportation pipeline can effectively save energy.

The thermal resistance of the envelope structure greatly affects the energy consumption of the cold storage. A cold storage with a high thermal resistance envelope can effectively reduce the heat transfer, thereby reducing the cooling load. In the design and construction of the cold storage, certain It is necessary to do a good job of thermal insulation of the building to prevent the occurrence of cold bridges; it is very important to design the heat transfer coefficient, color and thickness of the envelope reasonably. A better envelope can save a lot of energy. The thermal insulation materials are polystyrene, extruded board. It is necessary to deal with the cold bridge part of the cold storage warehouse for the envelope structure. The building usually produces cold bridges in various improper connections. When the cold bridges are generated, a large amount of energy will be lost, so it is necessary to deal with the cold bridges. Location: The part where the insulation layer is disconnected because the load-bearing structure needs to be continuous; the part of the ground and floor that crosses the deformation joint outside the door opening between the cold storage room and the freezing room leading to the hall; the insulation layer is broken because the load-bearing structure needs to be continuous open part. Choose energy-saving refrigeration preparation, choose a suitable compressor, give priority to an evaporative condenser, and choose a suitable evaporator; the type of compressor should be determined according to the scale and processing usage of the cold storage. Generally speaking, the COP of the screw compressor should be Higher than the piston machine, it is suitable for use in low temperature conditions with little load change, while small compressor units are more convenient to operate and more energy-saving in high temperature or air-conditioned storage; for cooling equipment, try to use air coolers instead of top row pipes , the use of the top row pipe is not only consumables, but also has poor cooling efficiency. The evaporator should try to use hot air to defrost or realize automatic defrosting to reduce the loss of electric energy; the evaporative condenser is preferred, which not only saves water pumps, cooling towers and pools The cost of the evaporative condenser is only 10% of that of water cooling, which saves electricity. The evaporative condenser should be arranged in a well-ventilated place as much as possible to avoid direct sunlight. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and clean rooms.

Optimize the air curtain at the entrance. The air curtain is usually installed above the gate, which not only facilitates entry and exit, but also prevents the exchange of indoor and outdoor air, and at the same time can play the role of dustproof, anti-pollution and anti-mosquito. Regular maintenance of the equipment, the cold storage equipment has a great influence on the energy consumption of the cold storage, the scale on the condenser tube wall will cause the condensing temperature to rise, the unqualified door will affect the opening and closing and consume energy, thermal insulation materials and moisture-proof materials Therefore, it is necessary to regularly supervise and manage various equipment of the cold storage, remove the dirt in time, and find the parts that are not conducive to energy saving.
