The term Cold room, refers to a specially built room, chamber or an enclosure that is well-insulated or lagged so as to prevent direct thermal flow out of the room. Cold rooms are extensively used for various industrial and commercial applications mainly involving storage, food processing and treatment, biochemical reaction and transportation of food products.
They are also used by industries as well as households for preservation of perishable items such as fruits and vegetables. Cold chambers also find utility in medical conditions such as cryotherapy where low temperatures down to -250 Celsius are required to be maintained stable over time inside laboratory chambers during scientific research. With advances in insulation technology, cold rooms can be used in varying array of applications that call for maintaining different types of temperatures across different time durations with precision control over temperature inside them.
Polyurethane (PUR), Polystyrene (PSR) and Polyisocyanurate (PIR) are the materials most commonly used in the construction of cold room body walls. The PUR, PSR and PIR panels used to construct a room’s insulation works by trapping air thus creating a cushioning layer between the inside of the room and the external environment. These panels are lightweight, easy to install, reduce noise levels and their specially designed sealing joints ensure no air enters or leaves room. These panels offer excellent heat-resistance qualities and provide an extremely effective insulation barrier against heat transfer from one side of the wall to another. The use of these panels also eliminates condensation formation within walls rooms which decreases maintenance costs as it eliminates possible corrosion or microbial growth due to dampness in interior environments.
The door of a cold room is an integral component and must be carefully chosen to ensure a safe, sustainable and secure environment for storing goods. A suitable door must be able to withstand and maintain the operating temperature within the cold room. The choice of a door (or doors) for any cold room depends on several factors such as size, purpose, safety, energy efficiency etc., making it a critical decision in any commercial cold storage. Depending upon the purpose and the nature of the stored goods, there are different types of doors available with distinct features that should be taken into consideration before selection. Another factor to consider is how much insulation value each door will provide in terms of thermal performance – this could potentially save businesses money in their operation costs.
There are several types of refrigeration units that can be used to power a cold room. The most commonly used are split type, roof mounted, mono-block or wall-mounted mono block, and ammonia (NH3) cooling systems. The split type refrigeration unit uses two separate components connected by tubing to create the cooling effect. It is the more affordable option and provides excellent cooling efficiency for colder temperatures. Roof mounted and wall-mounted mono block units are also similarly priced but require a lot of space for installation. Denser cooler temperatures can be achieved with the ammonia (NH3) cooling systems which usually requires professionals to install them.
Each type of refrigeration unit has their own advantages and disadvantages which makes it important to consider different factors like energy efficiency, size and noise levels when choosing which one is right for your use case.
