Where you place your cold room within your facility has a direct impact on energy efficiency, operational convenience, equipment lifespan, and food safety compliance. This is a decision worth thinking through carefully before construction begins.
Core Principles of Cold Room Placement
Minimise Heat Gain
A cold room works by continuously removing heat. The less external heat penetrates the room, the less work the refrigeration system has to do — and the lower your electricity bill. Wherever possible, avoid:
- Direct sunlight: South-facing or west-facing external walls receive intense afternoon sun in Kenya. A cold room built against these walls will have significantly higher running costs.
- Near heat sources: Keep cold rooms away from ovens, boilers, cooking lines, and areas of high activity that generate heat.
- Poor ventilation zones: The condenser unit (which expels heat) must be positioned where hot air can disperse freely. A condenser in a poorly ventilated corner will overheat and fail prematurely.
Proximity to Operations
The cold room should be close to where products are received, prepared, and dispatched. A cold room located far from the kitchen, loading bay, or production line creates inefficiency — staff leave doors open longer, warm air enters more frequently, and temperature spikes become routine. In food businesses, this is both an energy problem and a food safety problem.
Indoor vs. Outdoor Installation
Most cold rooms in Kenya are installed indoors or under a covered structure. Indoor installation is preferred because:
- Ambient temperatures are lower and more stable
- The condenser unit is protected from Kenya’s extreme sun and dust
- Security of the unit and its contents is easier to manage
Outdoor installation is possible (see article 10 for more detail) but requires shade canopies, weatherproof condenser units, and additional protective measures.
Floor and Structural Considerations
The floor beneath a cold room must be level, solid, and capable of bearing the combined weight of the structure, refrigeration equipment, and stored goods. Freezer rooms require insulated floors to prevent ground frost heave — a common problem where the cold room floor is laid directly on soil or poorly insulated concrete.
Ensure ceiling height is adequate: most cold room panels are manufactured in heights up to 3 metres. If your facility has lower ceilings, discuss this with your contractor early.
Drainage
Cold rooms generate condensation, defrost water, and occasional spillage. Position the room where drainage can be easily directed to a floor drain. This is particularly important for fish, meat, and dairy applications where hygiene standards are strict.
The ideal cold room location is shaded, well-ventilated, close to the point of use, and on a solid, level floor with good drainage. Spending time on placement before installation begins saves energy costs, maintenance headaches, and potential food safety issues for the entire life of the room.
