FIGURE 7-1 Major Compressor Types Compressors Dynamic Positive Displacement Axial Centrifugal Reciprocating Rotary DYNAMIC COMPRESSORS Dynamic compressors are nonpositive displacement compressors … Energy in the form of heat is removed from a low-temperature reservoir and transferred to a high-temperature reservoir. There are many structural types of this kind of compressor, among which screw, rolling rotor and sliding vane compressor are widely used. Refrigerant compressors 145 18 1. Another type, which is produced in large quantities, a scroll compressor, but still these compressors are not available in the amount normally encountered in industrial refrigeration.Rotary vane compressors are still used as a low stage compressors, but very little installed. The superheated vapo ur enters the compressor where its pressure is raised . 0000003196 00000 n See our Privacy Policy and User Agreement for details. 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 These types vary in method, utility, function, and purpose. Main types of compressors used in industrial refrigeration are screw, piston, centrifugal and rotary vane. 3.2 COMPRESSORS 3.2.1 Types of Compressor xref As air comes in through the inlet, rotating vanes push the air along into a tighter and tighter edge of the circle, effectively compressing it while using minimal effort and travel of the air itself. Low Pressure Side. Types of Refrigeration Vapour Compression Refrigeration Refrigeration cycle Condenser 4 Expansion Device Compressor 3 High Pressure Side. • The motor and compressor are directly coupled on the same shaft, with the motor inside the refrigeration circuit. Hermetic compressors • A hermetic or sealed compressor is one in which both compressor and motor are confined in a single outer welded steel shell. PPT. 0000002796 00000 n Starting a Split Phase Compressor. In earlier times, ice was either: 1. The most common, however, are positive displacement and dynamic. In other words in this type of refrigeration system compressor and condenser are not combined together in a single unit. Types of refrigeration system. Thus, they are called positive-displacement compressors. 0000000674 00000 n trailer 0000002947 00000 n 4TH YR. While the four types of refrigeration systems have many similarities, they have just as many differences. 0 Thus the need for a shaft seal with the consequent refrigerant leakage problem was eliminated. This compressor wine cooler holds up to 33 standard wine bottles at once and maintains an optimal environment for your most prized vintages. There are five basic types of compressors used in the HVAC industry. Now customize the name of a clipboard to store your clips. Compressors: There are mainly three types of compressors in use: Reciprocating compressor, Rotary compressor, Centrifugal compressor • Reciprocating and rotary compressors are more commonly used for small capacities but for lower evaporator temperatures. They are one of the best compressor type in rotary compressors.The air is compressed using two spiral elements. 18. Both of these types of compressors can be single- or multistage. Sharda University Made during the night by the cooling of water by radiation to the stratosphere. Screw compressor has a series of unique advantages, such as simple structure, high reliability, convenient operation and maintenance, mature technology and so on. Refrigeration compressors and air conditioning compressors provide air conditioning, heat pumping, and refrigeration for large-scale facilities and equipment. It then moves to the expansion valve, and the evaporator and it is finally sucked by the compressor again. 0000001459 00000 n The … These are preferred for higher … Individual knowledge of the equipments is required to understand the refrigeration system.

Looks like you’ve clipped this slide to already. 162 0 obj <>stream Liquid passes through expansion device, which reduces its pressure an d controls the flow into the evaporator . All the compressors are contained in a single room called the machine room while the condensers are fixated on roof tops for sufficient air flow to remove the heat from the condenser coils. These compressors are widely used in large capacity refrigeration and air conditioning systems. 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). Refrigeration Sales, Inc warrants the products it offers, to the original purchaser only, to be free from defects in materials and workmanship under normal use and service for a period of ninety (90) days from the date of installation. 0000001715 00000 n If you continue browsing the site, you agree to the use of cookies on this website. 0000006352 00000 n 0000002833 00000 n There are various types of compressors used in the refrigeration and air conditioning machines, these are: reciprocating, rotary, screw, centrifugal and scroll. Compressor forces more and more air into a storage tank, increasing the pressure. These systems consist of an evaporator, a condenser, a compressor and an expansion valve. Transported from colder regions, 2. F��cͫ���v��U�K���b������-O�G���� In other words, refrigeration is artificial (human-made) cooling. Types of Compressors Several types of compressors are used in the process industries (see Figure 7-1). Prevent possible explosion by relieving pressure caused by fire, coil blockage, or overheating of unit. To help you get ahead of the curve, we’ve broken down each one in some summaries below. MECHANICAL. Compressor . Alibaba.com offers 9,727 types refrigeration compressors products. conditioning can be classified by the type of input energy and the refrigeration process as follows: 1. p>������^9P19j_��P2�q�. %%EOF COMPRESSORS Compressors are machines designed to deliver gas at a pressure higher than that originally existing. Expansion . The main technical data of the components is also provided. Natural Cooling : In olden days refrigeration was achieved by natural means such as the use of ice or evaporative cooling. The type of oil may be mineral or synthetic to suit the compressor type, and also chosen so as not to react with the refrigerant type and other components in the system. & Tech, Amritsar. 2 types currently used, spring loaded and fusible metal plug View and Download PowerPoint Presentations on Types Of Hvac Compressor PPT. compressors and types 1. 1. In contrast, centrifugal compressors use the principle of dynamic compression, which involves converting energy from one … 0000045646 00000 n Centrifugal compressors (also known as turbo-compressors) are radial flow type, roto-dynamic compressors. TO THE TRAINER This PowerPoint presentation can be used to train people about the basics of refrigeration and air condonditioning. Refrigeration systems refer to the different physical components that make up the total refrigeration unit. For the proper functioning of the refrigeration … The maintenance is very important Minimum one day use is important in a weak to avoid rusting. Most refrigeration units with more than 1 pound of refrigerant are equipped with a pressure relieving safety device. 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. When tank pressure reaches its upper limit the air compressor shuts off. 0000002220 00000 n Types of Compresssors. M�!

The term refrigeration means cooling a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature). %PDF-1.4 %���� • Centrifugal compressors are essentially large discharge capacity compressors. Akshay Kr Mishra- 100106039 Vapor compression systems.In vapor compression systems, compressors activate the refriger- ant by compressing it to a higher pressure and higher temperature level after it has produced its refrigeration effect. Rotary Compressors • Rotary compressor function is in which fixed amount of air is displaced with each revolution.
