Cool Room warmer than desired?

Having a Cool Room running warmer than desired creates anxiety and stress.  You may lose your product.  Call Carroll Refrigeration and Electrical to save time, money and stress.

Potential Causes for Cool Room problems

• System is low on refrigerant

• Insufficient insulation in hot weather

• Insufficient ventilation

• Dark roof and hot sunny days

• Insufficient Airflow or airflow is not uniform

• Thermostat location that senses cold temperatures

 Potential Solutions for Cool Room problems

• Installing more refrigerant in a system that is low, is only a temporary measure.  Refrigeration systems do NOT use refrigerant. The only way a system can be low is if there is a leak.  Therefore, if this is the problem, it is imperative to find the leak and fix it. Yet, finding a leak can sometime be difficult. Electronic leak detectors help refrigeration mechanics find the leak.

• There are many thicknesses of insulating panel. So, ensure you have insulation thick enough to give you the best year-round use

• Do not install the equipment where it will recirculate it’s own hot air. Locating the remote equipment in a well ventilated area so it can breathe.

• Perth weather can be very hot. Dark coloured roofs are very hot. A light coloured roof can be up to 18 degrees cooler than a dark roof. Paint the roof white.

• Use of smoke generators can locate dead air spots. Options include relocating the evaporator coils, increasing the capacity of fans number of fans. You can also rearrange storage containers to allow more uniform airflow.

• Install thermostats in the average room airflow. If possible in return airflow to evaporator coils. Do not locate thermostats on cold walls, near doors, or near the cold air leaving evaporator coils.

4 Tips defeat Commercial Refrigerators Perth – temperature fluctuations!

Problems with temperature fluctuations

Commercial Refrigerators Perth Repair Services

Potential Causes

• The thermostat is not located in the ideal location hence it is not sensing average temperature of the room

• Airflow is not uniform throughout storage, air cannot flow easily in all areas

• Temperature difference across the evaporator coils is too large to maintain constant temperature

• Poor quality or insensitive thermostats

Potential Solutions

• Installing the thermostat in average room airflow will help.  The best location is usually in the return airflow to evaporator coils.  Keep the thermostat away from cold air leaving the coils, or hot product placed in the fridge.  Place thermostats away from warm/cold walls, doors and lights.

• So that you can locate dead air spots use a smoke generator. Install extra fans. Being that storage containers can prevent airflow and circulation, rearrange ensuring they are not packed tightly and do not touch the sides.  Also relocate evaporator coils or increase the capacity of their fans (if possible).

• For the purpose of lowering the temperature difference across the evaporator coils, adjust the controls.

• In general use quality controllers.  Also keep equipment well maintained is essential for uniform temperature control and vital for maintaining product quality.

Super Fridgie provides innovative solutions

With trusty van and tools at the ready Super Fridgie solves another ongoing problem.   In summer time if a cool Condenser too close to wallroom runs warmer than it should and the equipment is in good working order, the problem can be the location of the equipment.  Good air flow is imperative for a condenser to be able to work efficiently and effectively or it can cause the compressor to fail.  This would result in an emergency call to Super Fridgie to get things fixed asap.

When installed in a small court yard, against a wall with a cover over the top and in direct sun light, it is only a matter of time before things go wrong.   The Commercial Refrigeration equipment is working extremely hard trying to reach the desired temperature.   All the while your power bill is growing – a pet hate of Super Fridgie.

Super Fridgie

Rica and Derek from NeHo Asian Tapas had this exact problem.  He took Super Fridgie’s advice and had the condenser for his cool room relocated into an open air situation where it can breathe.   Super Fridgie also made a protective cover from the direct sun light which helps the condenser work efficiently – saving power.

Before relocating the condenser Rica’s cool room was running at 12 degrees on hot days.  Within 3 hours of the relocation the temperature had dropped to 4 degrees.

‘Peter & Robin from CRE were fantastic, they respond to our issue quickly when we called them. Peter took the time to investigate the issue, and explain to us clearly what caused the problem. We took his advise, and he helped us to relocate the condenser to the roof top where it has more air flow. This was done on a very hot day, they did such a good job. The quality of service is superb. Thanks guys.’  Derek & Rica NeHo Asian Tapas. 24/1/17
