Water cooled chillers cost more to install and maintain. Identify compressor components and explain the purpose of each. Centrifugal Air Conditioning Compressor. The cooling effect of refrigeration systems is generally quantified in tons of refrigeration. They are particularly suited to manufacturing processes that demand very clean air (class 0) such as pharmaceutical, food, electronics, etc. There are two sub categories for vapor compression chillers which are water cooled or air-cooled chillers and we’ll look at these shortly. You have entered an incorrect email address! Based on the working principle, refrigeration systems can be classified as vapor compression systems, vapor absorption systems, gas cycle systems, etc. They are also used in some industrial processes but we’re going to primarily focus on their application in air conditioning of buildings typically with Air Handling Units and Fan Coil Units. temperature and pressure ). An air compressor is direct connected to a heat engine. It contains cylinde rs, pistons, rods, a crankshaf t, and valves, similar to an automobile engine. The cooling tower will also use a fan to reject the heat. Air cooled chillers cost less to install because they have less equipment. Although dominant in lower-end refrigeration systems and air compressors, scroll compressors are beginning to make inroads into other markets. Capacity controlled via momentarily separating scrolls with solenoid valve and electronic modulation, Air cooled COP 2.9 – 4.15 Water cooled COP: 4.7 – 6.07, Typically, 1 compressor on water cooled, 1 or 2 compressors on air cooled, Uses two interlocking rotating helical rotors to compress the refrigerant, capacity is controlled via speed control or slider, Use heat to drive the refrigeration process, usually steam or hot water, Used in Medium to large buildings, Hospitals, Swimming centres, Heat Networks, No compressor, direct or indirect fired. Support our efforts to make even more engineering content. Furthermore, the mechanics for both are very similar. There are 3 types of chillers that cool things using air, water, and evaporation. The most common compressor type in industrial chillers is the scroll. 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. Take a closer look at how a chiller works in these different system types. There are three kinds of compressors used in central air-conditioning: piston compressor, screw compressor and centrifugal compressor. 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 chillers us air to remove heat while water chillers use, you guessed it, water. 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. Air Compressors are used in manufacturing, welding, constructions, power plants, ships, automobile … They use compression to raise the temperature of a low-pressure gas, and also remove vapor from the evaporator. This is used so that if a chiller fails you have a backup always ready to come online to take over and handle the cooling load. Rotary compressors are either rotating blade or stationary blade. 5. Types of Compressor A compressor is a mechanical device that increases the pressure of a gas or air by reducing its volume. They might also use a separate smaller air cooled chiller to handle the critical cooling loads such as computer and communication rooms. Describe the theory of operation for a compressor. Medium sized buildings with a cooling load of around 200 – 400 tons of refrigeration or 700 – 1,400 kW will typically use screw compressors or Turbocor compressors, these can be either water or air cooled, we’ll look at why that would be just shortly. Different types of process chillers fall under two main categories: (1) Vapor Absorption and (2)Vapor Compression. These are the most common types of chillers. These buildings might also use an absorption chiller if enough high quality heat is available. Our chillers use scroll compressors for the 1 and 2-ton models. The basic principle of the refrigerant equipments and the classification of those equipments are discussed here. You’ll find a reciprocating compressor in any of the ½ ton models we sell at North Slope Chillers. 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. Air-Cooling and Water-cooling chillers are further categorized by the type of compressor technology used. Lobe Type Air Compressor. 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. Water chillers remove heat by pumping water through a sealed condenser and dispersing it through the cooling tower.

Identify common compressor types and describe the operating principle of each. (Read more about how chillers work here.). Compressor Refrigeration System Components Evaporator Condenser / Receiver Expansion Device. Vapor absorption chillers will use a heat source to move the refrigerant around the system rather than using a mechanical compressor. Vapor compression chillers are the most commonly used and fit into two subcategories: air chillers and water chillers. Centrifugal chillers operate by using rotating impellers to compress the refrigerant and force it around the chiller. Using water evaporation to dissipate heat uses significantly less energy than blowing air across a hot surface. The Different Types of Cooling Compressors Compressor Types Positive Displacement Dynamic Reciprocating Rotary Centrifugal Vane Lobe Scroll Liquid Ring Axial Single-Acting Double-Acting Diaphragm Screw Reciprocating compressor (single-acting) A reciprocating compressor is also called a piston compressor which adopts the Let’s take a quick look at how each of these work, their applications, and the pros and cons of each. Air chillers are easy to instal and typically can be installed outside a building (no extra space requirements). This means more space within the building for business purposes. Water cooled chillers generally last longer because they are inside the building so deteriorate much slower. Simple in design. Small building with cooling loads under 200 tons or 700 kW will typically use scroll compressors or Turbocor compressors and are typically of air cooled design. 2 3 SCOPE OF THE COMPRESSORS HANDBOOK This handbook applies to the Embraco on-off compressors produced in Europe (the country of origin is indicated on the compressor label). Compressors 7 C H A P T E R Objectives After completing this chapter, you will be able to: Explain the purpose of compressors in the process industries. The only difference is that with an air cooled chiller, fans force air across the exposed tubes of the condenser which carry the heat away. Free PPT and PDF Download for COMPRESSOR: Compressors, fans, and blowers are devices which are designed in such a way that they deliver gas at a pressure which is more than the genuinely existing pressure.The features like a rise in pressure, working pressure, mechanical design and specific speed become the basis for the classification and differentiation. Compared to water chillers, air chillers are more prone to blockages and recirculation issues. These units are energy efficient, cost-efficient, and time-efficient. compressors and chillers, accounts for about 1.4 quads of primary energy1 use annually, while the total heating energy use in commercial building HVAC systems, including furnaces and boilers, accounts for about 1.7 quads of primary energy. 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. The rotary compressor can be divided into two types. If a commercial office type building uses a combined heat and power (CHP) engine these are often coupled with an absorption chiller which uses the waste heat from the combustion, but in this scenario these are mostly used in conjunction with electrically driven chillers. Both types of chillers have the same essential components which are, the evaporator, the compressor, the condenser and the expansion valve. Chillers are simply machines used to generate cold or chilled water which is distributed around buildings to provide air conditioning. Air cooled chillers require less space, they can sit on the roof and do not need a mechanical room. They are often found in hospitals and buildings with heated swimming pools.

If the chiller is going to be installed in an area with water restrictions then you don’t want this type. Compressor capacity:- It is the quantity of air actually delivered by a compressor in m 3 /minute or m 3 /sec. If you have a building with a medium to large cooling load then its recommended that you do not use only one oversized chiller to handle the entire cooling load. Additional Compressor Types. Water cooled chillers have a sealed condenser and water is pumped through to take the heat away and disperse this through the cooling tower. The Compressor, Its Components, and Its Functions . Chiller is a compressor based equipment that cools and controls the temperature of a liquid unlike the air conditioners, which cools the air. Details include the type of compressor, the refrigerant which it is … There might also be an absorption chiller within the central plant system, making use of waste heat, for example from a CHP engine, but these are mostly used alongside mechanical chillers. The majority of centrifugal chillers are water chillers (It’s extremely rare that you’ll find a centrifugal system in an air chiller). The reciprocating motion of the piston due to external power compresses the refrigerant inside the cylinder. The equipment used for removing the heat continuously for maintaining a low temperature in a space is called 'refrigerator'. This is thanks to water’s high heat capacity.
