Energy - saving and Consumption - reducing Schemes for Refrigeration in Dust - free Workshops
2024.11.07
In today's industrial production, the operation energy consumption of dust - free workshops, especially that of the refrigeration system, has become one of the key concerns of enterprises. Guangzhou Kunling Purification Equipment Co., Ltd. brings you the following practical energy - saving and consumption - reducing schemes for refrigeration in dust - free workshops.
I. Optimize the Design of the Refrigeration System
(1) Reasonable Selection
Accurately calculating the cooling load of the dust - free workshop is the key. Select refrigeration equipment precisely based on factors such as the workshop's area, heat generation of process equipment, number of personnel, and heat from lighting. Avoid oversized selection that leads to frequent start - stop of equipment and energy waste, or undersized selection that fails to meet the refrigeration demand. For example, for a dust - free workshop for electronic chip manufacturing, fully consider the high heat - generation characteristics of chip - manufacturing equipment and select compressors and condensers with appropriate cooling capacity.
(2) Optimization of System Layout
Reasonably plan the direction and length of refrigeration pipelines. Reduce resistance components such as elbows and reducers in the pipelines to lower the flow resistance of the refrigerant in the pipelines, thereby reducing the power consumption of the compressor. At the same time, optimize the layout of evaporators and condensers to ensure the uniform flow of air on the surface of heat exchangers and improve heat - exchange efficiency. For instance, adopt a parallel - type pipeline layout to make the refrigerant circulate more smoothly in the system.
II. Improve the Operating Efficiency of Equipment
(1) Regular Maintenance
Conduct regular maintenance and inspection of refrigeration equipment. Clean the surfaces of condensers and evaporators to remove dust and dirt and maintain good heat - transfer performance. Regularly check the lubricating oil level and quality of the compressor to ensure its normal lubrication and operation. For example, professionally cleaning the condenser once a quarter can effectively improve its heat - dissipation efficiency and reduce energy consumption.
(2) Precise Control Strategy
Adopt an advanced control system to achieve precise control of refrigeration temperature and humidity. Set up temperature sensors and controllers in different areas of the workshop according to the actual requirements of different areas to avoid over - refrigeration of the entire workshop. At the same time, set a reasonable temperature control range and avoid setting the temperature too low. For example, different production processes in a pharmaceutical dust - free workshop have different temperature requirements, and the temperature of each area can be controlled specifically instead of uniformly setting a too - low temperature.
III. Utilize Natural Cold Sources
(1) Seasonal Utilization
In winter or during transitional seasons, when the outside ambient temperature is low, natural cold sources can be used to refrigerate the dust - free workshop. Through the installation of a linkage device between the fresh - air system and the refrigeration system, when the outdoor air temperature meets the refrigeration requirements of the workshop, outdoor cold air is introduced to partially or completely replace the operation of the refrigeration unit. For example, in the northern winter, a large amount of low - temperature fresh air can be introduced for workshop cooling.
(2) Utilization of Diurnal Temperature Difference
In some regions with a large diurnal temperature difference, this characteristic can be utilized. At night when the temperature is low, cold storage equipment is used to store cold energy, and during the day when the temperature rises, the stored cold energy is released for workshop refrigeration, reducing the running time of the refrigeration unit during the day. For example, factories near some desert areas can make full use of the large diurnal temperature difference for energy conservation.
IV. Improve the Enclosure Structure of the Workshop
(1) Strengthen the Thermal Insulation Performance
Use high - performance thermal insulation materials for the walls, ceilings, and floors of the dust - free workshop. Reduce heat transfer between the inside and outside of the workshop and lower the refrigeration load. For example, use new - type thermal - insulation color - coated steel plates, which can better block heat compared with traditional materials.
(2) Reduce Air Leakage
Inspect and seal doors, windows, gaps, and other parts of the workshop where air leakage may occur. Prevent hot air from entering and cold air from leaking to maintain a stable temperature environment inside the workshop. For example, use air - tight doors and double - glazed windows with better sealing performance.
V. Energy Recovery and Utilization
(1) Condensing Heat Recovery
The condensing heat generated by the refrigeration system can be recovered and utilized. For example, the condensing heat can be used to heat domestic water in the workshop, pre - heat process water, or for winter heating in the workshop to improve the comprehensive energy utilization efficiency.
(2) Waste Heat Recovery
Collect the waste heat generated by process equipment in the workshop and transfer the waste heat to the refrigerant or air through a heat exchanger to assist the refrigeration system in operation and reduce the energy consumption of the refrigeration unit. For example, the heat dissipated by some electronic equipment can be reused through a heat - recovery system.
Through the comprehensive implementation of the above multiple schemes, enterprises can significantly reduce energy consumption while ensuring the refrigeration effect of the dust - free workshop, achieve the goal of energy conservation and emission reduction, save costs for the enterprise, and also make a positive contribution to the environmental protection cause.
