Industrial Air Cooled Screw Compressor Glycol Chiller 0C

Industrial glycol chiller is one kind of low-temperature chiller using glycol water as the circulating coolant to achieve minus temperature for industrial and process applications.The two types of ethylene glycol are ethylene glycol-based or propylene glycol-based. The antifreeze properties of ethylene glycol ensure that the coolant remains in a fluid state to reach its low cooling point.Glycol is recommended for all chiller units when operating temperatures are below 41°F (5°C). A glycol chiller unit consists of refrigeration components and pipes containing a glycol-water mixture as the coolant. The chilled fluid from the refrigeration unit is transported through pipes associated with the heat exchanger surrounding the heating process. After absorbing heat from the associated process, the heated coolant is returned to the refrigeration unit to be cooled, and the process is repeated.

What is the Difference Between Glycol Scroll Chiller and Glycol Screw Chiller?

There are two types of glycol chiller: one is air-cooled glycol chiller ,the other is water-cooled glycol chiller ;

Air-cooled glycol chillers use ambient air to dissipate heat from the processes. They are energy-efficient, space-saving, and less maintenance that helps save money.

Water-cooled glycol chillers use water from an external water cooling tower to dissipate heat from the processes. These systems are longer lifespan, Relatively quiet, and more consistent cooling performance than the air-cooled glycol chiller.

Why Glycol Is Used for Cooling?

The most commonly used coolant in a chiller is water or a mixture of water-glycol. Glycol-based coolants consist of either ethylene glycol or propylene glycol. The main advantage of glycol coolants is their anti-freeze properties. Pure water freezes at 0 degrees C, while 30% ethylene glycol freezes at -14 degrees C. The low freezing point of glycol mixtures makes them ideal for cooling items that are below the freezing point of water. Although glycol has a lower heat capacity than water (each kilogram of glycol is easier to heat than one kilogram of water), the high temperature difference allows the glycol mixture to dissipate heat more quickly than pure water. The glycol mixtures are more suitable for applications where the chiller must quickly dissipate a large number of heat. In addition to providing excellent heat transfer parameters, glycol tends to discourage algae growth in heat transfer equipment.

How Does Industrial Glycol Chiller Work?

A glycol chiller is composed of a refrigeration component and tubing containing a water-glycol mixture as coolant. Chilled fluid from the refrigeration unit is channeled through the piping associated with a thermal exchanger surrounding a heated process. After absorbing heat from the associated process, the hot coolant is returned to the refrigeration unit for cooling after which the process is repeated.


A glycol chiller consists of a compressor, an evaporator, a condenser, a throttling element, and an electric control system. Let’s see what’s the working principle of a glycol chiller:

Glycol Chiller Working Principle


The compressor of glycol chiller

Tongwei glycol chiller uses top screw-type compressor features energy efficiency, low noise, and long service time.

In order to ensure that the pressure inside the evaporator is low enough and that the refrigerant is at such a low temperature, the compressor is used to pump out the evaporated refrigerant and compress the low temperature and pressure into the high temperature and pressure refrigerant gas.


Condenser for a glycol chiller

Glycol chillers are designed and manufactured by Tongwei and feature a choice of air-cooled or water-cooled condensers.

The high-temperature and high-pressure refrigerant condenses into liquid in the condenser. The refrigerant in the condenser releases heat in the air or water that is cooler than it.


Thermal expansion valve in a glycol chiller

Thermal expansion valve plays an important role in industrial glycol chiller. The refrigerant of the  glycol chiller is reduced from the condensation pressure to the evaporation pressure, so the liquid from the condenser can be put into the liquid tank.At this time, the refrigerant is at normal temperature and high pressure, and then passes through the expansion valve to lower the boiling point, and the liquid enters the evaporator to absorb heat and evaporate.


The evaporator in a glycol chiller

The evaporator for industrial air cooled screw glycol chiller just is: shell and tube type heat exchanger.

The low-temperature and low-pressure refrigerant liquid passes through the thermal expansion valve and exchanges with the evaporator.

Once the heat is absorbed, it becomes saturated or superheated steam that can be returned to the compressor for refrigeration.


The Ratio of Water to Glycol to Use

It is important to use the proper ratio of glycol to water mixture in the cooling system depends on the coldest temperature you need during operation, as insufficient glycol can cause the system to freeze, possibly bursting pipes and even destroying the chiller evaporator even may damage the glycol chiller, while too much glycol to a chiller system will result in an inefficient system.


But what’s the best ratio for glycol and water mixtures? Please see below glycol ratio of glycol and water mixtures for the glycol chiller in your cooling process:

How I Can Choose The Right Industrial Air cooled Glycol Screw Chiller For Your Application?

There are four important chiller specifications you need consider when you choose a chiller for your application :the cooling capacity for chiller ,the voltage required for operation, the associated pump horsepower and flow rate (contact us for custom selection), refrigerant, and the evaporator type.


10.1Calculate Right Cooling Capacity For Chiller

One of the most frequently ask about how we can know the cooling capacity for chillers.  We use KW ,Ton, But/h,Kcal/h to choose chiller cooling capacity :1 KW=860 kcal/h ;  1 TON=3.517 KW;1 KW=3412 Btu/h;


There is also a formula to calculate the cooling capacity for chiller:.

Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-T2)/0.86

Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)

Oversize the chiller by 20% Ideal Size in KW = KW x 1.2

Noted : T1:Incoming Water Temperature (℃)      T2:Required Chilled Water Temperature(℃)    

   

For example, what size of chiller is required to cool 10m³ water from 35°c to 15 °c in 1 hour?

Temperature Differential = 35℃-15℃=20℃

Water Flow Rate = 10 m³/hour

Cooling Capacity in KW = 10 x 20 ÷ 0.86 = 232 KW

Oversize the chiller = 232 x 1.2 = 278.4KW

278.4 kw cooling capacity for chiller is required.


10.2 Power

Different countries and regions have different standards for industrial electricity, the common power supplies are 208-230V, 380-420V,440-480V,50Hz or 60Hz, 3phase.

Such in Philippines ,the power supply is 220V 60HZ 3PH , 380V 60HZ 3PH ,460V 60HZ 3PH;

in Singapore and Malaysia ,the power supply is 415V 50HZ 3PH;

in Mexico ,the power supply is 220V 60HZ 3PH;

In USA ,the power supply is 208V 60HZ 3PH;575V 60HZ 3PH;480V 60HZ 3PH and so on


10.3 Water Pump

When you decide the capacity/tonnage of the chiller, we will recommend you the suitable pump in KW,which standard water pump is about 2 bar .If you need more high water pressure , please us when you inquiry.


10.4 Refrigerant

R22, R410A, R407C, R404A, R134A are optional choices.

R22: good cooling effect, but R22 is considered a powerful greenhouse gas, so it’s forbidden in most countries.

R410A: eco-friendly, R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan, Europe, and the United States. R-410A operates at higher pressures than other refrigerants.

R407C: a good replacement for R22, good cooling effect.

R404A: suitable for application that requires low temperature(below -10°c).

R134A: a non-flammable gas used primarily as a “high-temperature” refrigerant, suitable for air-cooled chiller working at a high ambient temperature above 50℃.


Shipping Way of Industrial Air Cooled Glycol Screw Chiller

As a professional low temperature glycol chiller supplier &exporter,we have our own shipment forwarder to arrange the shipment .Our chiller machine is with plywood packing,which prevent damage during transportation and meet export standards.There are three ways can delivery your chiller unit :


1. Ship by Air: As the chiller is with compressor ,water pump and fans ,the compressed refrigerant and oil inside the compressor is a dangerous item with the possibility of explosion , so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shipping way. After the machine arrives at your destination, you need to add refrigerant by local professionals. The airline company also request us to provide many documents to prove that the chiller not a dangerous product. The freight cost by air is very high may be higher than the cost of chiller , So By air for delivery is not the mode of transport recommended to our customer.


2. Ship by Sea: The transportation time is longer than by air , but the freight cost is cheap ,and there is no need to add refrigerant after the equipment arrives at the destination.This shipping way is the most suitable mode of transportation for you to delivery your local port.


3.If you have your own shipment container in your other supplier in China, we can help you delivery the chiller machine to your supplier in any city of China .
