Refrigerator Bimetal Thermostat Adjustable Defrost Thermostat 2321799 2149849

Short Description:

Introduction：Defrosting Thermostat Fuse

The defrost thermostat is a bi-metallic switch which controls the temperature rise in the freezer compartment during the defrost cycle. The thermostat clips onto the evaporator to protect the defroster heating elements from damage. Once the temperature reaches a preset level, the defrost thermostat opens, shutting off electric current to the defroster heating elements. A malfunctioning thermostat can keep the defrost heating elements from turning on or keep them on too long, causing heat damage or even a fire.

Benefits of a Defrost Thermostat

In any refrigeration process or application the heat being transferred can cause condensation to form on the evaporator. If the temperature is low enough the gathered condensation will freeze, leaving a frost deposit on the evaporator. The frost will subsequently act as insulation on the evaporator pipes and reduce the efficiency of heat transfer, which in turn means the system needs to work harder to cool the environment sufficiently, or that the fridge cannot reach the setpoint at all.

This has repercussions on either the product not being kept or cooled to the correct temperature, which can increase instances of faulty product, or it means more energy is expended trying to maintain the correct temperature, increasing running costs. In either case there is a loss to the business due to wastage or higher overheads.

Defrost thermostats combat this by periodically melting any frost forming on the evaporator and allowing the water to drain away, keeping the moisture level in the environment as low as possible.
