To a consumer or end user, a refrigeration system is nothing more than a large fridge or freezer. Adjusting the thermostat simply raises or lowers the temperature within the space. Many facilities require refrigeration systems, most notably: grocery stores, convenience stores, distribution facilities, restaurants, and even warehouses. The installed system will allow the end user to control temperature; however, the system requirements vary from each project based on process, standards, and existing conditions. An engineered refrigeration system addresses the specific temperature and humidity requirements of both product and space while taking into consideration many design considerations. These considerations include: cost, installation, equipment selection, refrigerant selection, oil return, acoustics, power consumption, code requirements and regulations.
Low/Medium/High Temperature Refrigeration System Design
A refrigeration system is first selected based on the temperature range required for product storage.
- Low temperature systems (-40°F - +10°F) typical applications include: ice storage, reach in freezers, walk in freezers, ice cream cabinets.
- Medium temperature systems (-10°F - +30°F) typical applications include: refrigerators, beverage coolers, walk in coolers, dough retarders, bottle coolers, meat cases, milk and dairy cases.
- High temperature systems (+20°F - +55°F) typical applications include: dehumidifiers, florist refrigerators, produce coolers, mortuary and fur applications.
- Commercial equipment temperature rages typical range form (-10°F - +45°F).
