High Power Consumption of Constant Temperature Freezer and Its Solutions
2024-08-29
The following are several common reasons for the high power consumption of constant temperature cold storages:
- The selection of innovative, second-hand equipment and second-hand panels leads to increased power consumption.
Reason 1: The internal structure of second-hand equipment is worn. It is not as stable in operation as new equipment. Just like a second-hand car, it has a long service life. After being innovated, it has been in use for a long time, and many parts are worn, resulting in increased electricity costs.
Reason 2: For second-hand panels, the panels of constant temperature cold storages are generally used for about 10 years. With a long service life and after being disassembled and installed twice, many sealed places are damaged. The thermal insulation performance of polyurethane inside the library panels decreases, resulting in the loss of cooling capacity and poor thermal insulation effect. This extends the working time of the unit and leads to increased electricity costs.
Solution: Choose the constant temperature cold storage unit equipped by a regular company and try to choose less innovative or second-hand equipment. - Negligence during use and uncontrolled entry and exit times lead to increased electricity costs.
Reason 1: During the use of the constant temperature cold storage, the door is not closed and the light is not turned off in time. Heat enters, and the warehouse light is on for a long time. The temperature inside the warehouse rises, and the unit starts to operate.
Reason 2: When loading and unloading goods in the constant temperature cold storage, it is chosen at noon. At noon, the outdoor temperature is high, leading to the entry of temperature into the warehouse. In addition, the high heat of the goods themselves will also cause the unit to operate for a long time.
Solution: For those who need to frequently load and unload goods and cannot control the entry and exit times, an air curtain machine can be installed on the warehouse door. In this way, when loading and unloading goods each time, the air curtain machine can work to block the entry of heat from outside the warehouse, reduce the loss of cooling capacity inside the warehouse, and naturally the working time of the unit will decrease. - Failure to regularly maintain the constant temperature cold storage panels, compressors, air curtain machines, and failure to defrost the pipes leads to increased power consumption of the equipment.
Reason 1: Panels and equipment, like cars, also need regular maintenance. Now we should be clear. For a long time, the silica gel of constant temperature cold storage panels is easy to fall off, and the panels are easy to be knocked. In this way, the sealing effect is not good.
Reason 2: There are materials such as refrigeration oil in the unit that need to be replaced regularly. If not replaced for a long time, just like the transmission oil and engine oil of a car, it will turn black and thicken and affect the working effect.
Solution: Regularly maintain the constant temperature cold storage, check the sealing effect inside the warehouse, check whether there is a black colloid under the warehouse door and whether there is air flowing out. You can close the door tightly and then test with a lighter at the bottom to see if the fire will go out. If there is a phenomenon of cold leakage, you can inform the repair team to make adjustments. After all, they are all mechanical parts and will inevitably loosen after long-term use.
