Temporary Chillers: An In – Depth Look​

Introduction​

Temporary chillers serve as a practical solution for short – term cooling requirements. In many cases, they act as a stop – gap measure when regular cooling systems are unavailable, undergoing maintenance, or when additional cooling capacity is needed for a limited period. They provide a reliable means of maintaining desired temperatures in a variety of settings, from industrial facilities to commercial buildings and special events.​

Applications​

Emergency Cooling: When a permanent chiller in a data center fails, a temporary chiller can be rapidly deployed. Data centers generate a large amount of heat, and even a short period without proper cooling can lead to server overheating and potential data loss. Temporary chillers can keep the servers cool until the permanent system is repaired or replaced. Similarly, in a hospital, if the main cooling system malfunctions, a temporary chiller can ensure that critical areas like operating rooms, intensive care units, and pharmacy storage areas remain at the appropriate temperature to safeguard patient well – being and the integrity of medical supplies.​

Construction and Renovation Projects: During construction or renovation of buildings, the existing cooling infrastructure may be disrupted. For example, in a large office building undergoing a major overhaul, the installation of new HVAC systems may take several months. Temporary chillers can be used to cool the occupied areas of the building during this period, providing comfort to the tenants or workers. In industrial construction projects, such as building a new manufacturing plant, temporary chillers can be used to cool construction equipment and maintain suitable working conditions for workers, especially in hot climates.​

Event Cooling: Large – scale events like music festivals, trade shows, and sports events often require significant cooling. For instance, at an outdoor music festival in the summer, temporary chillers can be used to cool the backstage areas where performers and crew are located. In a convention center hosting a large trade show, temporary chillers can be installed to keep the exhibition halls at a comfortable temperature for attendees, exhibitors, and the electronics and equipment on display.​

Seasonal or Fluctuating Cooling Needs: Some businesses have seasonal or fluctuating cooling demands. A food processing plant may experience increased cooling requirements during the peak production seasons, such as during the harvest period when more fruits and vegetables need to be processed and stored at low temperatures. Temporary chillers can be rented or leased during these high – demand periods to supplement the existing cooling capacity and ensure product quality.​

Types of Temporary Chillers​

Air – Cooled Temporary Chillers: These are a popular choice due to their simplicity and ease of installation. Air – cooled chillers use ambient air to dissipate heat from the refrigerant in the condenser. They do not require a complex water – supply system, making them highly mobile. Small air – cooled temporary chillers are often used for residential or small – scale commercial applications, such as cooling a single office during a short – term renovation. Larger industrial – grade air – cooled temporary chillers can be deployed in factories or construction sites. They are available in a wide range of capacities, typically from a few tons of refrigeration (TR) to over 100 TR.​

Water – Cooled Temporary Chillers: Water – cooled temporary chillers are more energy – efficient compared to air – cooled models, especially in hot and humid environments. They use water, usually from a cooling tower or a water source, to cool the refrigerant in the condenser. Water – cooled chillers are often used in applications where higher cooling capacities are required, such as large – scale data centers or industrial processes. However, they require a reliable water supply and proper drainage. Temporary water – cooled chillers can be equipped with skid – mounted units for easy transportation and installation. Their capacities can range from 10 TR to several hundred TR, depending on the specific application.​

Portable Chillers: Portable chillers are a subset of temporary chillers that are designed for maximum mobility. They are often small in size and can be easily moved around using wheels or handles. Portable chillers are ideal for applications where cooling is needed in multiple locations within a facility. For example, in a large warehouse, a portable chiller can be moved from one storage area to another as required. They are available in both air – cooled and water – cooled versions, with capacities typically ranging from 1 – 10 TR.​

Advantages of Temporary Chillers​

Quick Deployment: Temporary chillers can be installed and operational within a short period. In emergency situations, such as a chiller breakdown, this rapid deployment can prevent significant losses. For example, a rental company can deliver and set up a temporary chiller in a data center within a few hours, minimizing the downtime of the servers.​

Cost – Effective for Short – Term Needs: Purchasing a permanent chiller for a short – term cooling requirement can be expensive. Renting or leasing a temporary chiller is often more cost – effective. This is especially true for businesses with seasonal or occasional cooling needs, as they do not have to bear the high upfront cost of purchasing a chiller, as well as the long – term maintenance and storage costs.​

Flexibility in Capacity: Temporary chillers are available in a wide range of capacities. This allows users to choose the exact cooling capacity required for their specific application. Whether it’s a small – scale event that needs a few tons of cooling or a large industrial project requiring hundreds of tons, there is a suitable temporary chiller available.​

No Long – Term Commitment: Using a temporary chiller eliminates the need for a long – term commitment. Once the cooling need is met, the chiller can be returned to the rental company. This is beneficial for businesses or organizations that are uncertain about their future cooling requirements or those that only need cooling for a one – time project.​

Considerations When Using Temporary Chillers​

Power Requirements: Temporary chillers, especially larger units, can consume a significant amount of power. It is essential to ensure that the electrical supply at the installation site can handle the power demand of the chiller. In some cases, additional electrical infrastructure, such as transformers or power cables, may need to be installed. For example, a large industrial temporary chiller may require a three – phase power supply with a specific voltage and amperage rating.​

Water Availability (for Water – Cooled Chillers): Water – cooled temporary chillers need a reliable source of water for cooling. The water quality also matters, as impurities can cause corrosion and fouling in the chiller’s components. A proper water treatment system may need to be installed to ensure the longevity of the chiller. Additionally, the water consumption of the chiller should be considered, especially in areas where water is scarce or expensive.​

Space for Installation: Temporary chillers, depending on their size and type, require a certain amount of space for installation. They need to be placed in a location that allows for proper ventilation (for air – cooled chillers) and easy access for maintenance. In a crowded construction site or a small office space, finding a suitable location for the chiller can be a challenge.​

Maintenance and Monitoring: Although temporary, these chillers still require regular maintenance to ensure optimal performance. This includes tasks such as checking refrigerant levels, cleaning the condenser and evaporator coils, and inspecting the electrical components. Some rental companies may offer maintenance services as part of the rental package. Additionally, continuous monitoring of the chiller’s performance, such as temperature and pressure readings, can help detect any potential issues early.
