Ice Age Innovation: The Latest Trends in Freezing Facilities

A freezing facility is a warehouse that preserves products (mainly food) at an optimal temperature for a long period of time. Cold storage facilities also preserve products by keeping them from getting spoiled in the short term.

The right choice of cold storage system depends on the type of business and product. It is important to make sure that the system chosen is not only efficient but also safe.

Walk in Cooler

Walk in coolers at freezing facilities keep refrigerated products a safe temperature for longer periods of time. These commercial coolers are designed to store all types of products, including frozen meats, fish, and dairy items.

A walk in cooler uses a condenser unit to cool the air inside of it. The thermostat in the cooler sets the desired air temperature, and when the air gets too hot, thi cong kho cap dong tai ha noi the condenser unit is turned on to start a cooling cycle. The fans in the condenser pull air over its coils, which helps cool the cooled air.

This process keeps the air within the unit cold and lowers its operating costs. It also reduces the stress on the evaporator and condenser, which are key to energy efficiency.

In addition to lowering energy use, a properly insulated walk in freezer or cooler also protects the interior components from damage due to excess humidity and warm air. This can lead to icing, which can damage the interior parts of the freezer or cooler.

As a general rule, it’s a good idea to check the panels and seals regularly for any air leaks. This will help prevent ice buildup and reduce the likelihood of it occurring.

Energy Efficiency

At a freezing facility, temperature control is crucial to maintaining the quality of products. Cooling equipment uses electricity and/or ammonia, or a combination of the two.

The energy efficiency of these systems can vary based on what type of product is being stored. For example, bread and rolls are typically cooled to lower temperatures than cookies and crackers.

To achieve the right balance of cooling capacity, operations managers should consider the exact types of products that will be stored in their facilities. It’s also a good idea to get a heating load calculation done for the machines to ensure that they’re providing enough heat.

Cold storage is a huge user of energy. By implementing energy efficiency measures, businesses can save money on their utility bills while lowering greenhouse gas emissions and other pollutants.

Choosing the right cooling equipment is key to achieving high efficiency. Be sure to select the proper system based on your product, its storage requirements, and your company’s budget.

Thermal Energy Storage (TES) is a long-duration energy storage solution that utilizes phase change material to store and manage the large amounts of electricity required by refrigeration equipment in cold storage facilities. TES can provide up to 35% reduction in energy costs while maintaining stable temperatures in the freezer.


Lineage Logistics’ Perth Amboy facility is one of more than 30 cold storage facilities it acquired from Preferred Freezer Services in 2019. The Lineage managers quickly acted to replace a challenged condenser at the facility, choosing to add options that will help ensure reliable, long-term operation of the equipment.

The new evaporative condenser is manufactured by Taneytown, Maryland-based Evapco. Its eco-PMC ellipti-fin coil construction offers superior heat rejection and minimizes water consumption.

This type of unit is often used in walk-in coolers and freezers, as well as processing plants and ice manufacturing operations. The evaporator coils have variable speed fan motors, and the system control system adjusts the fan speeds in response to space temperature.

It is important to consider the evaporator temperature and capacity when selecting and maintaining settings. This will ensure proper variable speed fan operation and savings.

In addition, the evaporator compressor should be controlled at a saturated evaporating temperature (SCT) that is lower than the design TD based on the design piping pressure drop and losses. This will achieve the lowest overall fan power usage and minimum average load periods for the compressors and condenser fans in the system.

The condenser will then trap the vapor sublimed and desorbed from the materials in the refrigeration system and convert it into ice by desublimation. The ice will then melt, draining the water vapor.
