At present, for enterprises producing, processing foodstuffs, pharmaceuticals, aquatic products or buildings, hotels, supermarkets … need refrigeration system to preserve products, the issue of cost Operation is always a matter of concern. In the process of operation, the cooling system consumes a lot of energy, which is mainly electricity. This consumption can account for 30-70% of total electricity consumption of the whole enterprise.
The issue of how to minimize the cost of power consumption for cooling and freezing is one of the issues that many businesses are most concerned about today. So how to save electricity costs when operating the refrigeration system? The following information will help you get answers.
In order to save energy costs without affecting the quality of the products or the process of exploiting or processing the products, we should apply the following methods:
Installation of insulation for cold pipes
Insulation is the thermal insulation between the refrigerant conduit and the environment with the main purpose of avoiding heat loss, so that the system operates more stably and consumes more power.
Installation of new high performance systems, replacing the old system.
For old systems that have been used for a long time, machines operating over time will consume more power than newer high-performance systems.
Use the best equipment
The cooling or freezing needs to be clearly defined to avoid waste in order to select the right mode and capacity.
Minimizes the infiltration of hot air from other sources
You need to minimize the infiltration of air into the cooling area of the refrigeration system by plastic sheeting, rolling doors or by using an isolation door. When installing, there should be no gaps and freezing areas should be kept away from heat areas.
Planning for warehousing, loading and unloading and shipping
Plan to store one or several times a day, do not store when the product is hot, transport products from freezer to cool place quickly, handle temperatures suitable for cooling and freezing.
Maintaining, cleaning the system regularly
Ensure that the air circulation system in the freezer room is not blocked. Avoid freezing air vapor. Ensure that the temperature is adjusted to suit the cooling demand. Regularly check the operation of the thermostat.
Easy to arrange products
Streamline your products so employees or customers can easily get the products they need to reduce the time and the number of times they open the door.
In addition, you should arrange areas close to each other, use less heat in the refrigerators and only turn on the lights when needed.
In addition, cold storage tanks are also an option to minimize the cost of power. Cold storage tanks are used to store the cooling capacity for air conditioning of central cooling systems serving large buildings using electrical refrigerators. Chillers usually stay at night because they do not usually provide cold loads. When the cold storage system is attached to the system, the chiller can work at night to store the refrigeration capacity and return it in daylight when needed. This refrigeration can replenish or completely replace the cooling of the Chiller during the day.
Hope that the information above will help your cooling system operating optimally and save power the most.
