How do cold room panel maintain temperature control
In critical environments such as food storage, pharmaceuticals, biotechnology and logistics, maintaining precise, stable temperatures is not only desirable, but necessary. So what role do cold storage panel play in maintaining stable temperatures, and how do they work?
The insulation function of cold room panel is a barrier to stable temperatures. This is not just a simple wall panel, but a precision engineering system.
In general, the internal storage conditions of cold storage are determined by three factors: temperature, humidity and air circulation rate. These factors are controlled by the operating refrigeration equipment and can be adjusted by changing the operating conditions of the equipment, and cold storage panel play an important stabilizing role.
Exceptional Thermal Insulation for cold storage panels
The basic function of a freezer panel is to dramatically reduce the transfer of heat between the controlled interior and the external environment. This feature is based on the construction of the cold storage panels itself. The cold storage panels consists of two thin and strong metal plates with a strong core material, which is made of rigid and low thermal conductivity insulation material. At present, the more used cold storage panels are PIR cold storage panel and PU cold storage panel, these two kinds of cold storage panels have high R-value, strong heat insulation performance, and can achieve the goal of controlling the temperature under a certain thickness (should not be less than 100mm).
Cold bridge effect of cold room panel
Continuity of thermal insulation of cold bridge effect of cold room panel. Unlike traditional stud-wall construction, which creates pathways through the wood or metal frame where heat can flow more easily (“thermal bridges”), the insulation in cold room panels runs continuously from edge to edge (cold bridges). The carefully designed tongue and groove laps of the cold room panel will allow for a tightly bonded panel to panel connection that will connect all of the insulating cores, thus creating a continuous thermal barrier throughout the walls, ceilings and floor surfaces, avoiding condensation and heat gain.
Sealed cold storage panel skin
Heat transfer isn’t just conduction through solid material; air leakage (convection) and moisture vapor diffusion are significant threats to temperature stability and energy efficiency. The sealing design of cold storage panel also plays an important role in heat insulation. The skin of the cold storage panel is generally made of stainless steel or galvanized steel. Such a surface provides a complete and solid structural performance and can prevent moisture from the warm and humid outside air from penetrating into the cold interior, thereby preventing it from condensing, freezing, reducing the insulation performance and causing ice.
High-precision cold storage panel installation
The installation of cold storage panel requires a professional installation team to carry out the construction, because only professional installation can control the temperature to a certain extent.
During the installation process, not only should the horizontal and vertical directions be completely matched, the joints should be completely matched, and tightly fitted fixings and accessories should be selected for installation, but sealants should also be applied to achieve the designed air tightness and steam tightness. In addition, sealed cold storage doors should be selected as the access path, and the cold storage doors should also be provided by qualified cold storage suppliers.
The above measures can stabilize the internal temperature of the cold storage, significantly reduce heat gain, minimize temperature fluctuations, and ensure the effective operation of the cold storage refrigeration system.
