The Refrigeration Cycle and a Guide to Buying a Commercial Fridge

Refrigeration is the process of removing and transferring heat from a space. The removal of heat lowers the temperature. For refrigeration to occur, the refrigerant is pumped through a closed refrigeration system. A refrigerant is a chemical compound that can be compressed or condensed as the cycle of refrigeration occurs. The cycle of refrigeration works on the principle that when a liquid refrigerant expands into a gas, it removes any heat present from the space. In a refrigeration cycle, there are two main processes that occur: evaporation and condensation.

These two processes are separated at different components of the refrigerator. The refrigeration cycle starts at the metering device, where the refrigerant expands and changes to vapour. The gas then moves to the compressor, where its temperature and pressure increase. The heated gases then flow through the heat exchanger, where the heat is removed but the high pressure remains.

The high-pressure gas is then transferred to the expander where its pressure is lowered, and as a result, the gas cools. As the heat is removed, the vapour changes back to a liquid state and is transferred to the metering device, which cools its temperature further as it enters the evaporator coil, ready to begin the cycle again. This cycles for domestic and commercial refrigeration are similar.

Buying a Commercial Refrigerator

Refrigeration plays an essential role in the hospitality industry. When purchasing a commercial fridge, it is important to pick out one that is powerful enough to preserve food even when warm air is constantly let inside the fridge. Commercial fridges are available in different sizes and models. When buying a commercial fridge, look at the following aspects:

  1. Material. The material used to manufacture a refrigerator is very important. Look for stainless steel fridges, which are easier to clean. Avoid buying fridges with plastic racks as the racks are less durable. Fridges made using aluminium are more prone to scratches and challenging to maintain sanitary conditions in.
  2. Size. Fridges come in different shapes and sizes. An easy way to measure the size of a commercial fridge is by the number of doors. Before you can buy a fridge, determine the intended location in your kitchen and measure the space to allow you to narrow down the size. Include the doorways that your fridge will need to fit through in your measurements. Also look at the interior measurements of a fridge and determine the extent of storage space you need.

Staying Warm and Keeping Cool: An HVAC Blog

Whether you are trying to stay warm or keep cool, a lot of the same elements are involved. For example, you need a well-insulated home and a functioning HVAC system. This blog is going to contain numerous posts about both heating and cooling. I plan to write about troubleshooting your HVAC system as well as about supporting it with the right windows, fans or other elements. I may also write shopping tips and guides on when to call for professional help. Before you start reading, let me introduce myself. My name is Ken. I was born in Winnipeg, Canada, where weather fluctuations are a fact of life, and a sturdy HVAC system is essential. While I was spending a gap year in England, I met my wife, Ariella, an Australian, and we've been living in Oz ever since. This is my first blog, and I hope you like it.
