How Free Cooling Can Save You Money

What is free cooling and how can it save you money and help with the environment. Well free cooling is an economic method of using low external air temperatures to help with chilling the water, it also can then be used for an industrial process. Or with the air conditioning systems in the green data center.

When it is cold outside you can help save energy with your chilled water system. You can do this by adding a plate-and-frame heat exchanger. What this does is provide chilled water production. All that really means is you can shut down the chillers compressor.

When you add a plate-and-frame heat exchanger it can save you so much energy costs that you can earn your money back from the plates' installation in about two years. The right time to put on the plate is when the temp outside reaches below the temp that the water required set point. It can save your business money and it is also good for the environment because you are using less energy to run your chilled water system.

If your water chiller is being run mechanically, and it is only being used to maintain a specific maximum humidity condition that would not be able to be done with indirect cooling, it can double your energy cost. Because then you can set the water chiller to the outside dew point, that will be satisfactory to your laboratory conditions.

You can use the plate and frame system when the chilled-water return temperature is greater than the cooling tower's supply water temperature. This method can save you evaporative cooling opportunities and it can also reduce the chillers function by one-third to one-half.

You do not need to produce more cooling than you actually need. When you produce more than what you need it wastes money and energy. Variable speed drives can vary the output of your water chiller that will help to meet your needs throughout the day. This will help you save money on energy costs.

It is also important to have the right sized unit installed. You have a very skilled employee at your company who you depend on to adjust the flow of the water or tower water in an effort to provide enough cooling? Chiller technology can take care of the problem. When you properly install the right sized chiller installed, you simply set the chiller temperature and the solid state "genius" inside the chiller maintains your constant source of chilled water.

With today's economy everyone is looking to save money this is a great way to do it. And it also helps you become more earth friendly.

Process Chillers - Process Chiller Basics

Water chillers are used in just about every industry where a component, be it machinery or product, needs to be cooled. Sometimes, however, simple water chillers are not strong enough, and a process chiller may be used. Process chillers differ from standard HVAC chillers in that they use refrigerant coolants like ammonia and halocarbons, and can provide a higher level of cooling capabilities than standard chillers. In this article, we'll take a look at some of the basic information regarding process chillers and how they are used in today's industries.

Process chillers are generally made up of four parts - compressors, evaporators, condensers, and metering devices. The refrigerant is sent to a heat source by a compressor, where it absorbs the heat because of its chemical properties. It then carries this heat to an evaporator, where it undergoes a phase change - it is converted into gas form and thus disperses the heat into the atmosphere, sometimes through a cooling tower to provide extra heat absorption. The condenser then turns the coolant back into a liquid form and sends it back to the compressor, where it is pushed through the cycle again. Metering devices provide a way to regulate the amount of flow and heat being absorbed.

Process chillers are used in a number of industrial applications, such as in the plastics industry, where they are used to reduce cycle times in injection molding by regulating the temperatures there. They are used in baking and other foods, because cooler water allows dough to be mixed for longer periods and thus increases the quality of the product, and can cool various food producing processes such as the creation of chocolate, meat massaging, and vegetable processing. It is used in pharmaceuticals, where emollient vats produce large amounts of heat and frequently disperse it through a process chiller. They are even used in printing applications, to regulate temperatures in rollers and presses to reduce stretching and bleeding.

A process chiller can provide a large amount of cooling to virtually any facility, with the ability to chill up to forty tons of water or other refrigerant at a time. There are various types of process chillers available, with different types of compressors and coolant systems, each with their own strengths and weaknesses. The important thing is to know how much water you need cooled and at what rate, so that you can properly assess the type of cooling you will need.
