Hydroponic Chiller

Hydroponics is a method of growing plants without soil, with the plants receiving their nutrients directly from a nutrient-rich water solution. Unlike traditional soil cultivation, hydroponic systems provide all the basic elements plants need to grow in a controlled, soilless environment.

In a hydroponic system, plants are typically grown in an inert growing medium such as perlite, rockwool, coir, or other soilless substrates. The roots of the plant are submerged or periodically exposed to a nutrient-rich water solution that contains a balanced mixture of essential minerals and nutrients that the plant needs to grow.

There are several types of hydroponic systems, each with its own way of delivering nutrients to plants:

Nutrient Film Technology (NFT): In this system, a thin layer of nutrient solution continuously flows through the plant roots, providing a continuous supply of nutrients and oxygen.

Drip Irrigation Systems: Drip irrigation systems deliver nutrient solution to the roots of each plant through a network of pipes and emitters, allowing for precise control of nutrient delivery.

Ebb and flow (ebb and flow): This system periodically injects nutrient solution into the growing medium and then allows the nutrient solution to drain away, providing oxygen to the roots.

Aeroponics: Plants are suspended in a fine mist of air or nutrient solution to maximize the roots‘ exposure to oxygen.

Deep Water Culture (DWC): In DWC, plant roots are suspended in a nutrient-rich, oxygenated aqueous solution. Air stones or diffusers are used to provide oxygen to the roots.

Wick System: Nutrient solution is drawn through the wick into the growing medium where it is absorbed by the plant roots.

2.What is A Hydroponic Chiller?

A hydroponic water chiller is a refrigeration system that provides process cooling to the hydroponic reservoir. Water temperatures that are too high will seriously affect plant growth. The ideal water temperature for hydroponics promotes a good balance between the plant‘s oxygen use and metabolism. For commercially grown plants, temperatures can be between 59 and 86 degrees Fahrenheit.

3.How Do Hydroponic Chillers Work?

A hydroponic water chiller works on the same principle as a standard industrial chiller. The nutrient-rich solution within the system is circulated through a chiller containing a cooling coil, cooling it to the desired temperature.

4.Why Need a Water Chiller System for Hydroponics?

Hydroponics is a type of hydroponics in which plants are grown in a nutrient-rich water-based solution instead of soil. Hydroponic systems, like traditional nurseries, require sunlight or grow lights to keep crops growing properly.

Temperature control is especially important when growing plants hydroponically because different plants grow best at different temperatures. Cucumbers, for example, thrive in high temperatures.

Using a water cooling system, reflective metal to protect the reservoir from ambient heat, or investing in a hydroponic chiller are all options for controlling the ambient temperature of your hydroponic reservoir. Industrial chillers have the highest cooling efficiency of any temperature control technology.

5.What’s the Difference Between Air-cooled & Water-cooled Hydroponic Chillers?There are two types of Hydroponicchiller: one is air-cooled Hydroponic chiller ,the other is water-cooled Hydroponic chiller ;

Air-cooled Hydroponic chillers use ambient air to dissipate heat from the brewing processes. They are energy-efficient, space-saving, and less maintenance that helps save money.
Water-cooled Hydroponic chillers use water from an external water cooling tower to dissipate heat from the brewing processes. These systems are longer lifespan, Relatively quiet, and more consistent cooling performance than the air-cooled Hydroponic chiller.

7.What Are The Main Components of Hydroponic Chillers?

7.1 Compressor

The compressor is the key mover in water chiller because it produces pressure variations to stir the refrigerant around.

From 1/2HP(1/2 Ton) to 60HP(5oTon) Hydroponic chiller , which is with Panasonic or Danfoss brand Scroll compressor ,
Above 60HP Hydroponic chiller,which is with Hanbell or Bitzer screw compressor;

7.2 Evaporator

The evaporator is a crucial component of air-cooled water chiller, as it is responsible for extracting heat from the liquid being cooled,it is located between the compressor and the expansion valve. There are three types of evaporators : coil in water tank evaporator , shell and tube evaporator, 304SS stainless steel plate type evaporator.

7.3 Water Pump
The water pump is designed to increase the pressure and the flow of the chilled water in a closed space.
Hydroponic Chiller is used with 304 Stainless Steel Water pump.

7.4 Condenser

The condenser for air-cooled Hydroponic cooler is equipped with efficient cross-seam fins and female threaded copper tubes for high heat exchange efficiency and good stability.Its function is to cool down the refrigerant steam released from the compressor into a liquid or gas-liquid mixture.

The condenser for water-cooled Hydroponic cooler is shell and tube ,with the internal copper tubes employing an outer thread embossing process.This design effectively enhances the heat exchange efficiency between the refrigerant and water during the process. Compared to traditional smooth copper tubes, the outer thread embossing process increases the surface area of the copper tubes, thereby expanding the contact area for heat exchange and improving the thermal conductivity of the condenser. This optimization design allows the condenser of the water-cooled chiller to transfer heat from the refrigerant to the water more rapidly and consistently, enabling the water to carry away the heat.

10.How to Choose Right Hydroponic Chiller for Your Hydroponic Process?

How to calculate right cooling capacity for your Hydroponic chillers?

▪ First, determine the approximate amount of water (in gallons) for your hydroponic system.

▪ Next, try to find the maximum temperature for your process. You can do this by turning on all heat-producing appliances or recording the system‘s temperature during the hottest times of the day.

▪ Use ice packs to cool the system to the desired temperature to avoid increasing the amount of water in the system.

▪ Once the desired temperature is reached, the ice is removed from the system and the process water is circulated.

▪ After removing the ice pack for the first time, record the system temperature.

▪ After 1 hour, record the current system temperature.

▪ Subtract the initial temperature from the current temperature and record this value, called the temperature difference.

▪ Use this simple formula to find your ideal chiller capacity in BTU/hr: Amount of water in system (gallons) * 8.34 * Temperature difference (°F)

▪ We can offer hydroponic water chillers ranging in capacity from 1/2 to 100 tons. They can keep the temperature within ±0.1℃ of your desired set point.

Types of Hydroponicchiller system?
There are two types of chiller :Air Cooled Hydroponic Chiller and Water Cooled Hydroponic Chiller.

Water cooled chiller needs a separated water cooling tower and water cooling pump ,if you don‘t have exsiting water cooling tower,we suggest you use air cooled chiller; But if your ambiemt temperature is very high above 55℃ ,we suggest you use water cooled chiller , as it is easier to dissipate heat for water cooled chiller with water cooling tower.
But Most customers use air cooled Hydroponicchiller ,which is more easily install and save space.

Whether chillers need built-in Tank or not？

In a chiller system, a tank is usually equipped to buffer the thermal load of the chiller.

But should we choose a built-in type of tank or an external type of tank?

A chiller with a built-in tank is easier to install and can be used simply by connecting a water pipe to your application.

But it has a limited capacity and is not suitable for applications with larger chilled water demands.External tank’s capacity can be customized according to specific needs.

It can buffer a larger heat load, store more chilled water, but the installation will be more troublesome.

If you don‘t have external water tank ,we suggest our chiller built-with water tank ,which is easy for you to install.
