Understanding the Element of Insulation When Building Freezer Rooms
Posted on: 30 July 2020
Freezer rooms are an essential accessory for any vendor who deals in the sale of fresh produce. Commodities such as vegetables, flowers and fruits do not have a long lifespan after you pluck them from the farm. You must store them in spaces with specialised conditions to keep them from going bad. Freezer rooms are an efficient and reliable resource for such a project. They create a cold atmosphere that prevents the actions of the enzymes contained in the fruits and vegetables. Freezer rooms rely on insulting materials and techniques to maintain an appropriate temperature for your produce.
Here is some information that will teach you everything you need to know about insulating freezer rooms, especially if you need to construct one.
Heat Transmission
The need for insulating a freezer room arises from the ability of heat to move from one space top the other. Therefore, the design elements introduced in the construction of a freezer must reduce the transmission and impact of the heat that creeps into your storage space. Essentially, heat will find its way to the cold storage space by any of the following means:
- Conduction: Conductions refers to the transfer of heat via a liquid, cold or gas due to contact between the molecules in a material.
- Radiation: Radiation allows heat to move in the form of an electromagnet wave, infrared radiation or light. It is energy emanating from a hot body.
- Convection: Convection is the transfer of heat when a mass of warm air, gas or liquid moves from one space to another. For example, convection will happen when warm air from an adjacent room moves into the freezer room when you open the door.
Attributes of Good Insulating Material
You need to be wary of the qualities of the materials you choose to insulate your freezer room. Look for a material with low thermal conductivity, meaning that it has limited capacity to transfer heat from one point to the other. Secondly, the material should have low moisture-vapour permeability. Such material will resist water absorption despite the cold temperature in the freezer room. Lastly, look out for a material with a durable build that can resist harsh chemical and cleaning solvents.
The Material to Choose
When building a freezer room, consider using the following insulating material:
- Polyurethane foam: polyurethane is an excellent material because it has a high content of non-connected microcells filled up by an inert gas. You can pour it in place by mixing the chemicals manually or mechanically. You can also spray the insulating material into place.
- Expanded polystyrene: expanded polystyrene is available in plastic foams comprising white beards or pearls. The mechanical composition makes them good at resisting heat transfer while keeping freezer rooms as cold as you like.
