Medical refrigerators are complicated machines, but their importance to your day-to-day operations can be overstated. Medical refrigerator failures can cause thousands of dollars in lost medical supplies and materials, making regular maintenance incredibly important. As complicated as these appliances may seem, the primary reason they fail is due to dirty condenser coils. Thankfully, you don’t need to be a medical refrigerator specialist to keep these devices in working order. Cleaning a condenser is simple and will extend the life of your medical refrigerator.Get more news about Condenser Expansion Machine,you can vist our website!
A condenser is an essential component in the refrigeration process. Also known as the heat exchanger, this component is responsible for cooling down the hot refrigerant gas before it becomes the type of super-chilled liquid essential for modern refrigeration. As condensers often use air to cool the refrigerant, they’re one of few fan components that are easily accessible as the component often uses a fan to intake air.
This cyclical process begins when the liquid refrigerant flows into the compressor. The compressor does what the name suggests: compresses and pressurizes the liquid refrigerant until it heats up and turns into a gas or vapor.
Once the refrigerant has been pressurized and heated to around 140°F, it flows into the condenser. This condenser (also known as a heat exchanger), uses air or water to cool the hot gas refrigerant before it flows into the expansion valve.
The expansion valve gives the refrigerant space to rapidly expand. This process dramatically cools the refrigerant as it moves into the evaporator. Thermodynamics continues to take effect in the evaporator as the cold refrigerant pulls heat from the storage compartment, cooling the compartment’s air temperature. The refrigerant ultimately leaves the evaporator in its gas form and flows back into the compressor to start the cycle over again.
How Does a Condenser Get Dirty?
As long as the refrigerator is running, the condenser will constantly pull in air to cool the refrigerant. The condenser fan is typically covered with a grill that is just wide enough to allow air to pass through while still protecting the component from large objects that could damage it.
Over time, dirt and other material floating through the air will collect on the grate, reducing its effectiveness. Dirty condensers cause medical refrigerators to cool less efficiently or to not produce any cold air at all. Additionally, the harder the condenser has to work to pull in air, the more like it is that the refrigerator’s motor will burn out from the added stress from the dirty condenser.
