It also keeps the investment at a level that makes sense.
Applications of chiller for cold storage
Chillerone’s chiller unit for cold storage provides steady cooling. It helps keep meat, seafood, dairy, and fresh produce in good shape for longer. With this, you lose less, and your products stay better in quality.
Big cold storage warehouses often struggle with many door cycles. Our water chillers cool the space fast. They also keep the set temperature steady. This helps cut down the chance of cold chain interruptions as much as possible.
Medicines, vaccines, blood products, and biological samples can be harmed by temperature changes. Chillerone water chillers help keep storage temperatures in a tight range. They also include safety features designed to support stable cold storage for drug handling.
In the chemical factory, you often pull heat out fast to keep the process steady. Chillerone’s chiller can manage the reaction temperature with good accuracy. That helps support safer operation and consistent product quality. It also helps your equipment last longer.
Chillerone’s chiller unit for cold storage keeps the cooling steady. The units also run quietly. For retail and food businesses, this helps keep products fresh. It also cuts down on daily spoilage from temperature issues.
You can use our products in tough places. Examples include ice sports sites and mushroom growing rooms. We also provide cooling setups made for your needs. These are for specific temperature targets that regular off-the-shelf units often cannot handle.
It depends on which refrigerant you choose and what your local rules require. We can supply different types, including R404A, R507, and R290. R290 comes from nature, has zero ODP, and has a very small GWP. For that reason, it is often viewed as a greener choice. Chillerone will suggest the refrigerant that fits your needs. We look at your application temperature range. We also review local environmental rules.
The price of a cold storage chiller is not one set number. It depends on things like the room size, the temperature you want to hold, the heat that needs to be removed, and how the condensing unit is built. It can also change based on the evaporator style, the insulation panel thickness, and what the site looks like during setup. To help us price it clearly, share your exact project details.
Our small-sized cold storage units are equipped with small-capacity standalone machines. Some of them support a 220V single-phase power supply. However, medium-sized and large-sized cold storage units, as well as high-temperature cooling units, usually require you to provide a three-phase 380V/415V power supply. This depends on the compressor power, startup method, and unit configuration. It is recommended to confirm the on-site power supply conditions before selecting the model. Our engineers will help you determine the suitable model.
- Clean the condenser fins and the evaporator fan every month. Also check the refrigeration pressure and check the sight glass.
- Every three months, test the electrical connections. Calibrate the thermostat. Then verify the defrosting system works.
- Once a year, arrange a full inspection by a professional. They should check for refrigerant leaks and assess the vibration in the piping.
With regular upkeep, you can lower the chance of surprise downtime and help water chillers last longer in cold storage.
Inside the compressor, parts may be worn, or liquid slugging. The fan blades can also bend, or the motor bearings can be worn out. Sometimes the problem is simpler, like loose bolts holding the unit to its base. Pipes that are not held firmly can cause vibration and resonance. The surface under the unit may also be uneven, which can throw things off. Finally, we recommend that you directly contact the after-sales team of Chillerone.
- First, look at the sight glass.
- Next, measure the evaporation pressure and the condensation pressure. Compare them to what you normally expect.
- After that, check the superheat or undercooling. See if the value is outside the usual range.
- Also, use an electronic leak detector. Scan the lines and fittings to find any spots that are leaking.
Only when you confirm a refrigerant loss and fix the leak should you add refrigerant. Do not add it just from a hunch.
Start by Figuring out What the Cold Storage Is Meant to Do
You need to decide if you are keeping food or other products chilled, freezing it, or running a fast freeze process.
Next, Set the Temperature You Want to Hold
Pick the range based on the kind of products you store:
- For fresh-keeping at higher temperatures, aim for 0°C to +10°C. This is for items like vegetables, fruit, dairy, and flowers when you want short storage time.
- For medium refrigeration, use -18°C to 0°C. This suits meat, seafood, and frozen foods when you need longer storage.
- For deep freezing, choose -25°C to -40°C. This fits rapid freezing for seafood, ice cream, and ready-to-eat meals that must freeze quickly.
After that, plan the main refrigeration components for that temperature level.
Compressor type, evaporator layout, and refrigerant choice will not be the same for each range. For instance, a low-temperature room usually needs a low-temperature compressor.
It may also need an oil separator and a hot gas defrost approach to keep running steadily over time.
Calculate the Total Heat Load for the Cold Storage
To find the overall heat load for a cold storage, split it into several pieces.
Heat Gain Through the Building Shell
This is the heat that comes in from outside. It moves through the walls, roof, and floor. The amount depends on the panel material, the panel thickness, and the temperature gap between indoor and outdoor air.
Heat from Cooling the Goods
This is the energy the products give off while they drop from their starting temperature to the target temperature inside the room.
Heat Added by Ventilation and Door Use
When doors are opened, warm outside air can get inside. That air raises the load. The same idea applies to outside air brought in by ventilation.
Heat Released by Equipment and People
Fans, lights, and other devices produce heat while running. People inside the space also add heat.
For small and mid-sized cold storage, you can use a quick estimate. For high-temperature refrigerated rooms, use about 150 W per cubic meter. For insulated cold rooms, use around 100 W per cubic meter. For frozen goods refrigeration, the estimate is roughly 150 to 250 W per cubic meter.
*Declaration:
This information is for your and the cold storage water chiller manufacturer’s reference only. For the most accurate calculation, it is recommended to entrust it to a professional engineering team.
Choose the Refrigeration Setup
Start by looking at the project size and the way it will be installed. Pick a split system, with a condensing unit plus an evaporator, or choose a monoblock unit if the cold storage is small. Then decide how the condenser rejects heat. You can go with an air-cooled method, which does not need a cooling tower and is easier to place. Or use a water-cooled method, which is more efficient and fits bigger jobs.
Pair the Condensing Unit with the Evaporator
Use the cooling load you calculated as your main guide. Select a condensing unit that has the right cooling capacity. Then select an evaporator that fits that choice. Once the cooling load is set, expect the condenser heat load to be about 1.5 times the evaporator heat load.
Account for Site Conditions and Extra Margin
In very hot weather, you may need more cooling capacity than in milder conditions. Another option is to enlarge the condenser coil. It is also smart to add a buffer of about 10% to 20%. This helps cover heat gain through pipelines, wear over time, and load growth during extreme summer weather.
Do the System Match, Not Just the Rating
Do not base the final decision only on HP or kW. The key is how the full set works together. The condensing unit, the evaporator, and the expansion valve must be matched so the system can deliver steady and efficient cooling.
Where to Place the Condensing Unit
Put the condensing unit close to the evaporator. This helps keep the refrigerant pipe short. It also cuts down heat loss. Keep it away from heaters and other heat sources. Do not let it sit in direct sun. Make sure there is a way for water to drain. If it will be used outdoors, add a cover so rain cannot get to it.
Airflow and Temperature Control
Keep at least 500 mm of space between the air-cooled unit and the wall. This spacing helps heat leave the unit. Do not point the air intake toward the discharge of other equipment. Also, do not let the air outlet blow right back into nearby areas. Keep the outlet away from windows used by people nearby. Leave clear space around the unit. Keep the surrounding air under 38°C.
Base Work and Vibration Control
Set the unit on a level base. It should stay steady. The slope should be small. Place anti-vibration pads or shock absorbers under each corner. This will help lower noise and shaking when the unit runs.
Power and Safety Checks
Use a separate power line for the unit. Do not share it with other electrical loads. Connect the grounding wire the right way. The grounding wire size should match the power wire size. After you finish the wiring, check the insulation. Use a 500 V multimeter between the circuit and ground. The reading must be at least 5 megohms. Do not store any flammable or explosive materials near the unit.
Refrigeration Piping Fitment
Each copper pipe must go through its own insulation sleeve. Then the pipe sections need to be fastened in place. The suction line that runs horizontally should tilt toward the compressor. Make sure the route is held tight, mainly near openings and at bends. The suction return line must provide the right oil transport so the lubricating oil can come back smoothly.
Joining the System and Sealing
The unit ships from the factory with dry nitrogen inside. Before you link the parts, measure the nitrogen pressure. This helps confirm the system stays dry and does not contain dirt or other matter. Seal the areas where parts pass through the support board. Also seal the gaps between the support board and the parts. Copper joints are welded. The weld points should be solid and look neat.
Startup Check and Review
Once the work is done, clean the system and run the required tests. Put the temperature control sensor into the return air inlet of the evaporator inside the unit. Hang it so it stays steady for accurate readings. Place the defrost control sensor into the evaporator fins. Do not position it near the electric heater tube. If you can, use a qualified installation team to handle the whole refrigeration setup.
Cold Storage Energy-Saving Steps
Adjust the Set Temperature
If you raise the target temperature a bit, you can cut power use while keeping the product condition within limits. A drop of 1°C can push energy use up by about 3% to 5%.
Improve Insulation on the Room Walls
Use solid insulation panels made from polyurethane. Make sure the panel thickness meets the needs for low-temperature work. For low-temperature storage, a thickness of 150 mm or more is often used. Better insulation helps limit heat loss through the walls and the cover.
Open Doors Less Often
Each time a door is left open, warm air flows in and the cooling system has to work harder. Try to reduce both how many times the door opens and how long it stays open. Use air curtains or fast roll shutters to limit cold air escaping. This helps most in logistics sites where trucks arrive and leave often.
Manage How Much Product Enters at One Time
Do not bring in a big batch of goods that are still at room temperature all at once. Store items in smaller lots. This can lower the highest demand periods and ease the load on the system.
Energy-Saving Steps for the Refrigeration System
Use Variable-Frequency Condensing Units
The compressor can change its output based on how much cooling the warehouse needs. If there are fewer goods or demand is low at night, the speed can drop. This can cut compressor electricity use by over 30%. It also avoids the extra losses that come from the repeated start and stop of fixed-frequency units.
Keep the Condenser Fins Clean
When the fins get dirty or clogged, they cannot release heat well. Heat transfer drops, the condensation temperature rises, and the compressor draws more power. Plan to clean the condenser fins about once every three months.
Keep the Refrigerant Amount Right
Too little refrigerant lowers evaporation pressure and weakens cooling. Too much refrigerant raises condensation pressure and increases energy use. Check the sight glass and monitor system pressure on a regular schedule.
Defrost on Time
If thick frost forms on the evaporator, airflow becomes poor. Heat exchange then gets worse. Make sure the defrost system works properly. Set the defrost timing based on how fast frost builds.
Pick the Right Type of Condensation
Water-cooled units can be 15% to 25% more efficient than air-cooled units. They fit centralized cooling systems with high demand. But they need a cooling tower. You should review whether water is available and what the water cost will be.
Energy Savings Start at the System Match Stage
The biggest gains show up when the condensing unit and the evaporator fit each other well. If they do not match, the system can spend a long time running in a poor and inefficient range. To avoid that, you need to set the right operating point from the start. Use the cold storage size, the target temperature, the local environment, and the load behavior. Then do careful heat load calculations and match the system so the equipment stays in a reasonable operating range. This is the key step to lower long-run energy use.
