You might need to use chillers with multiple compressors that can work independently from one another so that if 1 compressor fails the chiller can still remain partly operational. Chillers are simply machines used to generate cold or chilled water which is distributed around buildings to provide air conditioning. This type of compressor is most often used in window air conditioners, refrigeration appliances, and heat pumps. They might also use a separate smaller air cooled chiller to handle the critical cooling loads such as computer and communication rooms. You’ll find a reciprocating compressor in any of the ½ ton models we sell at North Slope Chillers. You also need to consider the criticality of the building and the redundancy required, known as N+1, where by “N” is the number of chillers you need and the “+1” or “+2” or “+3” etc is the number of backup chillers needed to continue to meet cooling capacity in the event of a failure. Air cooled chillers typically do not have as long a service life as water cooled chillers because they are exposed to the sun, rain, frost, snow and wind which deteriorate the materials. These systems work by using a piston and chamber to compress the refrigerant. Different types of process chillers fall under two main categories: (1) Vapor Absorption and (2)Vapor Compression. Screw Compressors Technology varies and depending on the age of the building you own or manage the type of chiller you have may fit into one of the following categories.

The unit is derived from the cooling rate available per hour from 1 ton (1 short ton = 2000 pounds = 907.18 kg) of ice, when it melts over a period of 24 hours. Found in our larger units, CWB, CWE & CWT, scroll compressors work by compressing the refrigerant between two spiral plates, one stationary and one orbiting. (2) Classification by condenser cooling mode According to the cooling mode of condenser, it can be divided into water cooling, air cooling and evaporative cooling. Capacity controlled via amount of heat entering, Idea for using waste heat or cheap heat, sometimes used to offset peak electricity costs, Typically combined with mechanical chillers. Evaporator control in industrial refrigeration engineering. They are often found in hospitals and buildings with heated swimming pools. Types of Compressor A compressor is a mechanical device that increases the pressure of a gas or air by reducing its volume. There are 3 types of chillers that cool things using air, water, and evaporation. Save my name, email, and website in this browser for the next time I comment. vapor compression chillers use an electrically driven mechanical compressor to force a refrigerant around the system while vapor absorption chillers use heat to move the refrigerant around the system. Chiller compressor types. Scroll compressors are used in both air and water coolers. The other type has the blade which remains stationary and is part of the compressor housing assembly. Condensers. You also have the option to opt-out of these cookies. Water cooled chillers take up space within the building, they need mechanical plant rooms, more risers, more pumps, cooling towers and water treatment, this space therefore can’t be used for business purposes. Let’s take a quick look at how each of these work, their applications, and the pros and cons of each. These units are energy efficient, cost-efficient, and time-efficient. Air cooled chillers require less maintenance compared to water cooled chillers, again because they have less equipment, Air cooled chiller systems are much simpler design and do not need another set of pumps for the condenser, Air cooled chillers sit outside the building, their fans and compressors will create noise which the surrounding areas might be able to hear, although some measures can be implemented to reduce this. Water-cooled chillers are typically more efficient than air-cooled chillers. They are particularly suited to manufacturing processes that demand very clean air (class 0) such as pharmaceutical, food, electronics, etc. In this article we’ll be covering the different types of chillers available, where they are used as well as the pros and cons of each chiller type along with some examples of where they’re used.

Compared to water chillers, air chillers are more prone to blockages and recirculation issues. The first way to categorise a chiller is by defining whether it is a vapor compression or vapor absorption type chiller. different types of unloading refrigeration compressor with best price and finish evaluation from a variety item for all item. For example you have a building with a cooling load of 2,200 Tons, then you should use combinations such as two 1,200 ton chillers or two 900 tones and a 500 ton or a 1,000 ton and two 700 ton chillers etc. An air compressor is direct connected to a heat engine. Air cooled chillers can suffer from damage, blockages and re-circulation issues. It is a powerhouse of a design and is able to handle significantly larger loads than the other compressor types. The basic principle of the refrigerant equipments and the classification of those equipments are discussed here. Vapor compression chillers are the most commonly used and fit into two subcategories: air chillers and water chillers. Water cooled chillers generally last longer because they are inside the building so deteriorate much slower. Vapor Compressor Chillers. Centrifugal chillers operate by using rotating impellers to compress the refrigerant and force it around the chiller. [1] There are two sub categories for vapor compression chillers which are water cooled or air-cooled chillers and we’ll look at these shortly. Vapour compression chillers use an electrically driven mechanical compressor to force a refrigerant around the system. Advantages. Types of Chiller. Example Mechanical Center. 5. In the last session, we had discussed Vapor Compression Refrigeration Cycle and in today's session, we can discuss in detail the concept of Refrigeration along with its Definition, Unit, Classification of Refrigerants and Applications. As the name implies, it uses centrifugal force to pull in the refrigerant gas and then spins it rapidly with an impeller to compress it. Although dominant in lower-end refrigeration systems and air compressors, scroll compressors are beginning to make inroads into other markets. Thank you for that simple but very clear explanation. Now, this does vary based on the compressor type, system and oil type, but is a generally accepted rule in the absence of a more detailed guideline. Unfortunately many building owners want the cheapest upfront option, but this is a bad idea because for a little extra they could have bought a more efficient chiller which will be cheaper to operate especially as chillers can last for around 15 – 25+ years in operation, so it will have paid for itself multiple times and would have resulted in reduced environmental emissions. The components of the system are the same as in the absorption type – we have an evaporator, a condenser, and an expansion unit. Vapor compression chillers are the most common and include (1) air chillers and (2) water/fluid chillers.
