ITC+ air-cooled chiller 100L (2024)

FAQs

Why is my chiller not cooling enough? ›

There are several possible causes of inadequate cooling in a chiller. Here are some potential causes and how to address them: Low refrigerant levels: The chiller won't be able to cool efficiently if the refrigerant levels are too low. Check the refrigerant levels and replace them as necessary to solve this issue.

Two common factors that can prevent chillers from starting include loose wiring and a blown fuse/circuit breaker. Moreover, a power switch in the off state may prevent the chiller from running. Operators must check the equipment for these common problems to ensure the system runs effectively.

Capacity Range

Air-cooled chillers come in sizes ranging from 7.5 – 500 tons. Meanwhile, water-cooled chillers offer a higher cooling capacity of 10 – 4,000 tons.

Signs of low freon include blowing warm air regardless of how long it's running, taking longer than normal to cool down, or having ice on the refrigerant line. You might also hear strange noises or see a spike in your electricity bill.

Divide Q (BTUs per hour) by 12,000 (the number of BTUs in one ton of cooling capacity). This yields the chiller capacity required to handle the process heat load in tons per hour: Example: 240,000/12,000= 20 tons/hr.

The efficiency of a chiller is usually measured by its COP (coefficient of performance). The COP is calculated by dividing the cooling output in watts by the power input in watts. A higher COP means that more heat will be removed from a space for less energy input.

For anyone familiar with chiller sizing, 2.4 GPM/ton will give you a 10F delta-T across the evaporator. For cooling tower sizing, the rule of thumb is 3.0 GPM/ton for a 10F delta-T across the tower. You may also be aware that although a cooling ton is 12,000 BTUH, a heat rejection ton is 15,000 BTUH.

What temperature should a chiller run at? ›

Generally, temperatures of between 45 and 50 degrees are suitable for cooling equipment. Pharmaceutical uses include use of chilled water in manufacturing and cool storage. Usually, 35 to 46 degrees is the recommended temperature for refrigeration during transport and storage of most cold-chain medications.

Hook a pump in a bucket of water hook it up to the chiller and run it to see if the water gets cold.. May be the only way to test it..

The typical life cycle of a chiller depends on its type. On average, an air-cooled chiller's lifespan is anywhere from 15 years to 20 years. A water-cooled chiller is normally closer to 20 to 30 years. Where your chiller is located and the conditions it's under can also affect its life expectancy.

Under standard rating conditions at full load operation, the minimum required coefficient of performance (COP) ranges from 2.40 to 3.06 for air-cooled chillers and from 3.80 to 6.39 for water-cooled chillers.

CFM is cubic feet per minute of air that will be discharged into the conditioned space. CFM shows the volume of air entering the room per minute (as it is cubic feet per minute). TR is tonnage of refrigeration which means amount of heat extracted to produce one ton of ice.

Insufficient refrigerant will cause the pressure in the system to be abnormal, resulting in a decrease in suction pressure, low-pressure alarm of the chiller, and equipment shutdown. The leakage of refrigerant can be from the compressor, condenser, filter, expansion valve and evaporator, etc.

There are several causes for a refrigerator that doesn't cool, including dirty condenser coils, poor ventilation, improper installation, faulty or dirty gasket seals, unorganized food storage, appliance location and malfunctioning internal parts.

For air-cooled condensers, dust and debris buildup on fins and fan blades can inhibit air flow, lowering the cooling capacity. For water-cooled condensers, heat transfer can be reduced by scale formation, biological growth, or corrosion.
