Supermarket refrigeration is usually carried out for four different types of temperature ranges. The high temperature is normally used to maintain a temperature range of 50-60’F and that’s where you want the product to be cool, not colder or frozen. The application includes flower shops and air conditioning used in supermarkets. Medium temperature ranges from 35-50’F and includes any dairy product like cheese, milk, yogurt, or beer where you want the product to be colder. The low temp ranges from 0 up until -20’F. This is where all the frozen stuff needs to be stored like frozen foods, ice creams, and ice itself. Also, we have an extra low-temperature range which is used to freeze anything under-20 up to -50’F. The applications of extra low refrigeration include ice rinks, and petrochemical and pharmaceutical products which require extra low temperatures. Supermarket refrigeration is achieved by running remote compressors from the glass door fridges up to refrigeration racks and then from that rack to the condensing unit on the roof. Supermarket/Grocery store refrigeration requires a large amount of piping and everything needs to be properly sized for the glass doors to work properly. All of the systems communicate with each other with the help of controllers which keep a record of each and everything depending on which one is used. Usually, when the fridge/freezer goes down, it usually calls the alarm out telling me something is wrong with the system. These types of systems require a high level of understanding and years of experience to deal with.
