Low temperature cold storage operation energy saving steps

How to make the low-temperature cold storage more energy-saving in the later actual operation management, this is a problem that many friends of low-temperature cold storage are currently concerned, especially for the operation of large-scale cold storage cold storage, the steps of energy-saving operation of low-temperature cold storage are better. It can reduce the cost of low-temperature cold storage all year round. Let's talk about the specific points of energy saving in low-temperature cold storage.

*It is the refrigeration system of the low-temperature cold storage. In the actual operation, the operating conditions are constantly changing. Only by relying on the careful operation of the cold storage management personnel and accurately adjusting the operation of the refrigeration equipment can the refrigeration system always be in the ideal working state of Zui. To achieve energy efficient results. Therefore, accurate and timely adjustment of the refrigeration system is an important step in the energy-saving operation of low-temperature cold storage. Low temperature cold storage operation energy saving steps

The second is that the power consumption of the cold storage is calculated according to the amount of cold storage in the low temperature refrigerator. It usually consists of two parts: one is the cooling capacity when the goods are cooled and refrigerated; the other is the low temperature cold storage itself (ie, the envelope structure) ) and the amount of cooling required for operation management. The key to saving electricity is the utilization of low-temperature cold storage. The low-temperature cold storage with low utilization rate consumes more cold and consumes more electricity. In actual operation, the motor power of the compressor is selected according to the refrigeration capacity of the machine, that is, the cooling capacity of the warehouse is smaller than the refrigeration capacity of the refrigerator. When the low-temperature cold storage is operated in the off-season, the compressor is operated as a big horse-drawn car, which wastes electric energy because of the small amount of goods placed in the low-temperature cold storage. Therefore, in the off-season, the goods in several refrigerated rooms can be stored in time according to the storage temperature to reduce energy consumption. Therefore, the rational use of the warehouse, energy saving and consumption reduction is also an important step in the energy saving of low temperature cold storage.

The third is based on the comprehensive consideration of the area, height and warehouse temperature between the cold storage. The lighting in the cold storage is generally concentrated in the work area. The lights should be turned off in time to ensure the safety of the operators, so as to reduce the heat load and power consumption of the warehouse. At the same time, it is necessary to use high-efficiency, low-consumption and high-voltage lighting fixtures to reduce the frequency of lamp replacement. LED lighting system has the advantages of environmental protection, uniform illumination, good luminous efficiency at low temperature and high power supply efficiency. It is a promising new light source and the development direction of the lighting system in low temperature cold storage in the future. Therefore, the energy-saving cold storage lighting of the lighting system in the cold storage should be based on safety, science and rationality. From the perspective of energy saving and environmental protection, it is also a step that cannot be ignored.

After the zui is based on the actual data, when there is a 0.1mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will drop by 2.5 Â°C, the power consumption will increase by more than 10%; When the water pipe wall fouling reaches 1.5mm, the condensation temperature will increase by 2.8Â°C compared with the original temperature, and the power consumption will increase by 9.7%. When the refrigeration system is mixed with non-condensable gas, the partial pressure value will reach 0.196MPa. The power consumption will increase by about 18%. Therefore, the importance of fresh oil discharge, descaling and air release in the cold storage refrigeration system can be seen. Therefore, regular oil discharge, descaling and air release are also important to ensure good heat exchange. Low temperature cold storage operation energy saving steps

Dome Fixed Focus Camera

The Dome Fixed Focus Camera/ Dome Fixed Focus Camera Indoor/ Dome Fixed Focus Webcam/ Fixed Focus Dome Webcam Night Vision/ IR Fixed Focus dome camera/ Fixed Focus Dome Camera 360Â°belongs to both the Fixed Focus Camera and the Dome Camera. So what is the Dome Camera?

The Dome Camera, as the name implies, has the dome shape, and this dome shape is exactly the origin of this name "Dome camera". The Dome Camera is very suitable to be used in the office places and places with the high-grade decoration because of its small size and beautiful appearance. The Dome Camera is composed of a camera, an automatic iris manual zoom lens, a dome cover with the excellent sealing performance, and a precise camera mounting bracket; and its biggest feature is its exquisite design, beautiful appearance and easy installation.

With the security surveillance cameras applied extensively and deeply, in the pursuit of the convenient installation and debugging, and the full coordination with the the building environment(both beautiful and concealed), the Dome Camera is developed. Now the Dome Camera has been widely used in the TV surveillance projects.

Although the Dome Camera's composition has many similarities with the Bullet Camera, for example, both are fixed cameras, the Dome Camera has the delicate protective cover and mounting bracket, while the Bullet Camera needs to be equipped with a protective cover. The Dome Camera has a zoom lens with the small zoom range and the lens is not easy to replace; while the zoom range of the Bullet Camera depends on the selected lens, from several times to several times, and the lens replacement is very convenient. Dome cameras are mostly used in indoor small-scale monitoring occasions, such as the entrances and exits, passages, elevator cars, etc. of important parts; while the scope of Bullet Camera's application is very wide, according to the selection of different lenses, long-distance or wide-angle monitoring can be realized, and the application occasions are much wider than that of the Dome Camera.

With surveillance applications wider and wider; due to the convenience of installation and debugging, and the concealment of the surveillance, the dome camera has been widely applied to the indoor surveillance, such as the places with the ceiling and the rarely changing light. The Dome Camera technology also changes very quickly. For example, firstly, the camera shooting function of the Dome Camera is not different from the high-performance Bullet Camera, and the Dome Camera is miniaturized; Secondly, the lens of the Dome Camera is also automatic iris + manual zoom, and the zoom range gradually increases; Thirdly, the overall sealing performance of the Dome Camera is better, especially the lower dome, it is made thin and uniform, with better light transmittance and less light loss; Last but not the least, the mechanical design of the mounting bracket is more exquisite, which makes the adjustment of the camera position very convenient, and the three-dimensional adjustable universal joint bracket has appeared.

In conclusion, compared with the Bullet Camera, the Dome Fixed Focus Camera also has many advantages, and we should choose the suitable type according to our appliying occassions.
