Walk-in refrigeration

Walk-in refrigerators and freezers are very large insulated enclosed spaces for storing and / or exhibiting refrigerated or frozen foods or other perishable items. They are mainly used in the restaurant industry and restaurant industry.

(Commercial refrigerators and freezers used for supermarkets and food processing and packaging may become larger, usually supplied by a central refrigeration system.)

The working temperature of the walk-in refrigerator is higher than 0 ° C. and lower than 13 ° C., and the working temperature of the walk-in freezer is lower than 0 ° C. or lower than 0 ° C.

They are not regulated by Canadian energy efficiency regulations and have not received ENERGY STAR® certification for high efficiency

However, there are some energy-saving parts that can be used to assemble more energy efficient walk-in refrigerators and freezers.

A typical walk-in refrigerator or refrigeration system is shown below. The room is cooled by a packaged integrated or split refrigeration system.

The refrigerant continuously circulates from the compressor to the condenser, enters the expansion device, passes through the evaporator and returns to the compressor.

The refrigerant absorbs heat from the room and throws away heat by evaporation and condensation in a sealed refrigeration system. Heat may be released into the building, outdoors or cooling water.

Evaporator fan control operates at variable speed while the compressor is off or repeats on and off.

The evaporator fan controller increases the energy efficiency of the walking inchler and chiller by reducing the airflow when the compressor is off and by significantly reducing the power of the fan motor during the shutdown cycle. This process allows you to operate the walk-in operation in a state close to peak efficiency and reduce the power consumption when not in use. An evaporator fan controller that meets PG & E requirements will receive a discount of $ 75 per controller. It is important to always look for the Energy Star label when purchasing new restaurant equipment. ENERGY STAR certified products reduce energy consumption, especially for refrigeration systems, compared to competing products. Several ENERGY STAR qualified commercial refrigerators and freezers also offer a variety of discount opportunities. These products will greatly reduce the cost of the restaurant and save an average of 30% of annual electricity consumption of the refrigerant.

The design of the walk-in cooler and the freezer greatly affects energy saving. For refrigeration energy management, an important design path specifically planned for each equipment is required. Size is important here. It is because we need to consider the quantity / type of stock, the temperature of stock, and the equipment / personnel used to operate on walk-in in refrigeration calculation. Overload or over-capacity walk-in effects will not be cooled as efficiently as the correct size.

A walk-in type refrigerator or freezer keeps a large amount of food at an optimum temperature for a long time. Therefore, when choosing the manufacturer of the walk-in refrigerator, this is an important decision. The walk-in fridge can be used for nearly 10 years. Do they mainly use modular design? When looking for a walk-in refrigerator, make sure that the manufacturer mainly uses modular design. A variety of standard modular options that are easy to customize will ultimately offer better opportunities to obtain solutions tailored to your needs without paying custom prices.
