Types of warehouse cooling systems

A warehouse cooling system is vital for keeping products in good condition. Several types of chillers and refrigerated warehouses are available for use. The most common ones are listed here.

• Central chiller cooling systems

  Using a central unit to cool a large space is an effective method. Optimum cooling and energy efficiency can be achieved with the least number of machines. Central chillers work by removing heat from chilled water, which is then circulated through air handling units, cooling coils, and other refrigeration equipment. The most common central chillers are air-cooled and water-cooled chillers.

• Modular chiller cooling systems

  Modular chillers cool a large space using multiple smaller, self-contained chillers. Unlike central chillers, which have only one central cooling unit, modular has several cooling units that are sequentially turned on and off, depending on the level of cooling that is required at that time. As more cooling is required, more units can be added. It is a good option if the cooling needs will increase in the future.

• Air handler unit cooling systems

  Air handler units (AHU) blowers move a large volume of air over cooling coils that are connected to a central chilled water system. Outside air is drawn in and conditioned before being sent to the warehouse. The main parts of an AHU are a blower, cooling coil, ductwork, filters, and dust removal equipment. An AHU does not include its own cooling generator.

• Fan cooling systems

  A fan-based cooling system supplies cool air to the entire warehouse. Fans with a high volume of air movement (known as HVLS fans) are used to create a strong wind chill effect and cool easily. Other methods of fan-assisted cooling include evaporative cooling or swamp coolers, which are very energy efficient. In humid places, warehouse cooling system fans become essential parts of the dehumidifier.

• Refrigerated warehouses

  Machine-based cold rooms or walk-in freezers are examples of how refrigerated warehouses work. The air in a large space is cooled to preserve items. Shelving and access to products are important to make sure they can be taken out easily. Refrigerated vehicles are another example of how refrigerated warehouses work on smaller scales.

• Deep Freeze Cold Storage

  A deep freeze warehouse cooling system stores goods at sub-zero temperatures. An example is how ice cream is made and stored. Freezing items helps preserve their qualities for much longer than cooling them does.

• Batty storage system

  A batty storage system arranges products in bays. It uses a cooling coil in an air conditioning unit to store products in multi-story buildings. Aisles are created so that AC units can easily come to do service and maintenance.

• Pharmaceutical warehouses

  Pharmaceutical warehouses need to maintain precise humidity and temperature levels. This is often done through integrated building management systems that can automatically adjust the cooling system as needed.

Specifications and maintenance warehouse cooling system

Specifications

Some of the general specifications related to a warehouse cooling system are as follows.

• Temperature range: The temperature range denotes the specific temperatures that a warehouse cooling system can achieve. This specification often includes the maximum and minimum temperatures that a cooling system can reach. For instance, a cooling system with a temperature can maintain a temperature of -20°C to +20°C is useful for different types of warehousing needs.
• Capacity: The capacity of a warehouse cooling system speaks to the amount of space that the system can cool. This is usually expressed in cubic feet or square meters. The capacity of a cooling system is directly related to its refrigerant compressor size. Some cooling systems can efficiently cool an area of up to 10,000 square feet.
• Energy efficiency: The energy efficiency of a warehouse cooling system is a measure of the energy used during the process of cooling. This can include Energy Star ratings, energy efficiency ratios (EER), or coefficients of performance (COP). A high energy efficiency rating indicates that the system consumes less energy to perform the same cooling task.
• Noise level: The noise level produced by a warehouse cooling system is often measured in decibels (dB). This can include operational noise from the compressor, fans, and other components. In the case of cooling warehousing systems that are located near residential areas, it is important to consider the noise level the system produces so as to minimize noise pollution and disturbances to the surrounding communities. Most manufacturers provide the allowable noise level that is measured in dB.
• Refrigerant type: Different cooling systems use different refrigerants. Common refrigerants include R-22, R-410A, R-134A, etc. These refrigerants have different properties and advantages, and the choice of refrigerant also affects the energy efficiency and environmental impact of the cooling system.

Maintenance

Regular maintenance of a warehouse cooling system extends the lifespan and ensures it works optimally. Here are some of the maintenance tips for a warehouse refrigeration system:

• Regular inspection: Users should check the entire cooling system on a frequent basis for signs of damage or wear. They should be very quick to notice things like a warped or cracked condenser coil, poor insulation, or even unusual noises/sounds. Regular inspections allow coolings system users to notice issues as they happen early enough and get them fixed.
• Clean condenser and evaporator coils: Over time, dirt, dust, and debris can build up and accumulate over the coils, which will affect the overall performance and efficiency of the cooling system. Regular cleaning of the condenser and evaporator coils will ensure proper airflow and heat exchange are facilitated. Generally, the process of cleaning the coils involves vacuuming or brushing the coils to remove any form of debris or dirt. People with advanced skills and know-how can also use coil cleaners to improve the effectiveness and efficiency of the cleaning process.
• Check refrigerant levels: The refrigerant in a cooling system is what absorbs and releases heat to facilitate the cooling process. Ideally, proper refrigerant levels enable the system to function optimally. Warehouse owners/managers should frequently check the refrigerant levels in the cooling system and top up whenever necessary.
• Regular lubrication: Regular lubrication of moving parts in the system, such as the condenser fan, motor, and evaporator fan, reduces wear and tear and ensures smooth and easy operation. Lubrication also lowers the chances of power consumption rising as a result of stuck/immobile components.

Scenarios

A warehouse cooling system has the following applications:

• Logistics Warehouses

  A logistics warehouse uses a cooling system to maintain its goods at the optimal temperature. For example, a cold storage room with a cooling unit keeps the temperature low to preserve perishable food items.

• Pharmaceutical Warehouses

  Pharmaceutical companies use the cooling system to protect temperature-sensitive drugs and medical supplies. A drug that needs to be refrigerated is stored in a climate-controlled room so that it can maintain its efficacy and safety.

• Retail Distribution Centers

  A distribution center may use a cooling system to extend the shelf life of stored products before they are shipped to retailers. For instance, a DC may have a refrigerated warehouse portion where frozen and chilled products are temporarily held before distribution.
