New Refrigeration Equipment for Your Business

By: Miles Depace


Are you thinking of acquiring a new commercial refrigerator? The commercial reach-in fridge is almost certainly the most common type of refrigerator. The retail customer segment typically imagines a fridge to be what the reach-in type. Reach-ins are used by both huge retail venues such as megamarkets to tiny ones such as gas station marts, and everything in the middle. Spoilable items that require both quick availability and low temperature environments are typically stored in reach-in appliances. Reach-ins are not appropriate for extremely long-term storage, but instead are most suitable for products that are shuffled in and out of use during the course of the day. The reach-in fridge hatches are constantly getting stressed as they are frequently used by many employees.

This puts a high energy requirement on such kinds of fridges. A commercial fridge and a residential refrigerator are formally different by a set of requirements composed by NSF. A standards company named NSF - not to be mixed up with the National Science Foundation which is a separate entity, has been formalizing standards for business-use freezers.

The standards company dictates that business refrigerators must satisfy particular size and electricity requirements to clearly separate them from house-hold appliances. Within the category of reach-in commericial fridges, there are approximately two kinds. The first is a member of the class of so-named display fridges, and the other long-period repository units. Consumer navigate glass doors to get refrigerated items. To the consumer, the ability to see into the refrigerator suggsts locating and buying goods is faster and simpler. For the employee, the glass doors make simple the identifying of the desired item. Both situations benefit from the glass doors as they decrease the need for opening and closing the refrigerator. The repository units are differentiated only by the feature that these have an opaque door.

A strong metal is chosen for the material of the doors. Are there differences in the internal workings of commerce-use reach-in fridges and house-hold use appliances ? The condenser of a fridge are the coils which allow refrigeration gases to be compressed and expel heat. Within, the refrigerants expand and cool. Condenser coils can be situated remotely at a different venue or placed directly on the fridge case in reach-in units. Placing the tubes much further away helps reduce the negative effects of the heat expulsion. For the situation where the tubes are mounted onto the fridge body, frequently it is desirable to place them on the underside where a fan blades dissipate the heat. The reason is that business venues get quite hot.

Environmental control is helped by expulsion of thermal energy at the ground. The other important element of a refrigerator is the evaporator. This element acts the converse role of the condenser tubes. Within, the evaporator is the location where the refrigeration freon gasifies, cooling the inside. By drawing water from air onto the surface of the evaporator, a chilling effect is achieved. The negative effect is an increase in ice buildup, typically resolved by the automatic ice-removal systems of advanced fridges.
