Features of a Portable Chiller

What are the Main Components of Portable Chiller?

1. Water System

Pump Assembly: Portable Chiller’s pump assembly circulates chilled liquid to the process loop.

The pump assembly is purely made of stainless steel to sustain water quality during working operations.

Reservoir: The vented reservoir is designed for the Portable Chiller application to maintain the flow rate.

The reservoir of your Portable Chiller provides a stable water temperature even in different load conditions.

2. Refrigeration System

Compressor: Compressors take low pressure and low-temperature refrigerant gas and compress the refrigerant gas into high pressure and high temperature.

Air Cooled Condenser: The air-cooled condenser eliminates heat from the compressed refrigerant gas. The action makes the gas “condense” into a fluid state still under great pressure.

Airflow across the condenser is accomplished utilizing a motor-driven fan get-together.

Water Cooled Condenser: The water-cooled condenser eliminates heat from the compacted refrigerant gas. As the heat is taken out, the gas “condenses” into a fluid state, still under great tension.

Water controller valves are utilized on all models of the Portable Chiller to control the refrigerant head pressure by adjusting the condenser water flow.

Filter Drier: The filter drier of your Portable Chiller eliminates contaminants and humidity from the fluid refrigerant.

Refrigerant Sight Glass: The refrigerant sight glass shows refrigerant charge and humidity content.

Expansion Valve: The expansion valve of the Portable Chiller obstructs the flow of refrigerant fluid into the evaporator and produces a pressure drop in the refrigerant system that allows the fluid refrigerant to “boil off” inside the evaporator.

Evaporator: The evaporator is a brazed plate heat exchanger where the refrigerant liquid is permitted to evaporate (boil-off) to assimilate heat (BTU) from the process fluid.

As the heat is retained, the process fluid is chilled.

Capacity Control Solenoid: The Portable Chiller is outfitted with a capacity control option.

The capacity control includes matches the Portable Chiller’s ability to the cooling load to give temperature control and to prevent short cycling of the compressor.

High/Low-Pressure Switch: The high and low-pressure switches secure the refrigeration system from use working conditions.

Portable Chiller might be equipped with either customizable or non-movable ‘fixed’ high and low-pressure switches.

Standard Flow of Portable Air-cooled chiller: A “standard flow” chiller system has a coordinated tank.

It’s utilized in a closed-loop cooling application where all the water pumped from the chiller returns to the central unit under the pressure produced by the pump.

Reverse Flow of Portable Air-cooled chiller: A “reverse flow” Portable Chiller is without a tank.

It’s a part of an open-loop cooling application where an external is utilized.

The water in this tank is gravity taken into the chiller pump, through the chiller and filter, and back to the processor to the tank.

Water Cooled Portable Chiller

As you may have experienced, a water-cooled Portable Chiller uses water to chill off the warm air that has been pulled in.

Likewise, as your Portable Chiller works hard to cool down your application, it heats up.

All of this heat is also removed by incoming water.

Water-Cooled Portable Chiller is slightly more energy-effective than air-cooled unit, commonly utilizing less amperage to work.

If your facility has a chiller system, the Water Cooled Portable Chiller is the most effective option to cool down your application.

It doesn’t need any ducting, making them an independent Portable Chiller. Because you don’t need to remove the heat of the room, installation is very simple.

You need just to plug in the electricity and connect it to the water supply, all done.

The controls of a portable air-cooled chiller are coordinated to include every motor starter and need a single point electrical connection.

Standard Flow of Portable Air-cooled chiller: A “standard flow” chiller system has a coordinated tank.

How to choose the Right Portable Chiller for your Application?

While choosing the best Portable Chiller, you should consider your cooling needs and what stresses you put the unit under.

For Portable Chiller selection here are some important points which will help you out in choosing the right one for your application.

• Coolant temperature
• Heat load
• Coolant flow
• Condenser heat dispersal

Let’s go through each of the above points more closely.

Coolant Temperature: The coolant temperature quantifies the coldest the chilling fluid reaches in the Portable Chiller.

When it reaches the process, the cooling liquid absorbs heat from the encompassing air and the process, rising its heat.

The temperature of the cooling fluid will help to decide how much heat it can retain.

Heat Load: Heat load refers to the quantity of heat produced by your process.

The higher the heat load, the more impressive the Portable Chiller should be to remove the excess heat.

The heat load is estimated in British Thermal Units (BTUs) per hour.

Figure out the heat load by multiplying the coolant flow in gallons per minute, the particular gravity, the temperature change, and 499.8 to change pounds over to gallons.

Heat Load (BTUs) = Coolant Flow (gallons each minute) x cooling fluid obvious gravity x change in temperature x 499.8

To determine the tonnage needed to deal with your heat production, divide the heat load by 12,000.

Cooling Load (T) = Heat Load ÷ 12,000

Pressure and Coolant Flow: The rate of coolant flow and pressure influence a fluid’s capacity to remove heat.

The coolant flow rate utilizes the heat load divided by the result of the coolant’s particular gravity and the temperature adjustment.

Coolant Flow = Heat Load ÷ (cooling fluid gravity x change in temperature)

The size of the pipes the coolant moves through will decide the pressure.

A well-made Portable Chiller will allow proper pressure to secure your Portable Chiller from any kind of damage.

Condenser Heat Dissipation: How the condenser removes heat has an effect.

You have the choices for both air-cooled Portable Chiller and water-cooled Portable Chiller.

If you intend to utilize your portable outside in freezing temperatures, an air-cooled portable might be better.

In any case, if you need higher productivity, a water-cooled Portable Chiller in controlled environments might be your better choice.
