Want to know if the power consumption of installing a small cold storage is affected by those factors?
Small cold storage installations are generally divided into indoor and outdoor types. 1. Ambient temperature and humidity outside the cold storage installation: temperature is +35 ° C; relative humidity is 80%. 2. Set temperature in cold storage: fresh storage cold storage: +5～-5°C; refrigerated cold storage: -5～-20°C; low temperature cold storage: -25°C 3. Into cold storage food temperature: L grade cold storage: +30°C; D Class, J class cold storage: +15 °C. 4. The effective volume of the stacked cold storage is about 69% of the nominal volume. When storing fruits and vegetables, multiply by the correction factor of 0.8. 5. The daily purchase volume is 8-10% of the effective volume of the cold storage.
(1) Temperature: First, the power consumption of the cold storage is greatly related to the temperature that needs to be set inside the cold storage. Under the same conditions, the lower the temperature, the greater the power of the compressor set and other equipment.
(2) Capacity: The larger the volume, the greater the required cooling capacity. The configured unit power is greater. The greater the power consumption.
(3) The external environment: the climatic conditions of the cold storage installation and construction address are also important reasons that affect the starting frequency of the compressor.
(4) Number of door opening: The frequent opening of the cold storage is the loss of cold in the warehouse, which will also increase the operating cost.
(5) The shape of the goods: such as "blocky" products and "flaky" products, the required cooling capacity, and the central temperature of the library will be very different, which is also a factor that causes changes in energy consumption.
Let's take a look at the average energy consumption value of common fruit and vegetable cold storage. If you want to accurately calculate your actual cold storage energy consumption,:
Reference list:
Cold storage capacity 40 (cubic meters) Power consumption 4.5 (hourly / kw)
Cold storage capacity 80 (cubic meters) Power consumption 6.5 (hourly / kw)
Cold storage capacity 100 (cubic meters) Power consumption 8 (hourly / kw)
Cold storage capacity 150 (cubic meters) Power consumption 9.5 (hourly / kw)
Cold storage capacity 200 (cubic meters) Power consumption 11.5 (hourly / kw)
Cold storage capacity 500 (cubic meters) Power consumption 18 (hourly / kw)
