In other words in this type of refrigeration system compressor and condenser are not combined together in a single unit. There are many structural types of this kind of compressor, among which screw, rolling rotor and sliding vane compressor are widely used. 1. Hermetic compressors • A hermetic or sealed compressor is one in which both compressor and motor are confined in a single outer welded steel shell. 0000002947 00000 n 0000000016 00000 n types of refrigeration compressors - NewAir AWC330E NewAir AWC330E 33 Bottle Compressor Wine Cooler. Condenser . The high pressure sup erheated gas is cooled in several stages in the co ndenser . These types vary in method, utility, function, and purpose. Most refrigeration units with more than 1 pound of refrigerant are equipped with a pressure relieving safety device. Refrigeration compressors and air conditioning compressors provide air conditioning, heat pumping, and refrigeration for large-scale facilities and equipment. See our User Agreement and Privacy Policy. %%EOF The third type of rotary compressor is the vane type. 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. PPT. 0000034409 00000 n The most common, however, are positive displacement and dynamic. 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. 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. Refrigerant compressors The maintenance is very important Minimum one day use is important in a weak to avoid rusting. Thus, they are called positive-displacement compressors. 162 0 obj <>stream 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). In earlier times, ice was either: 1. The compressors are one of the most important parts of the refrigeration cycle. These systems consist of an evaporator, a condenser, a compressor and an expansion valve. 0000001216 00000 n 1 Evaporator.

Screw compressor has a series of unique advantages, such as simple structure, high reliability, convenient operation and maintenance, mature technology and so on. SCROLL TYPE COMPRESSOR • A scroll compressor operating in reverse is known as a scroll expander, and can be used to generate mechanical work from the expansion of a fluid, compressed air or gas. This system uses a set of vanes that are slightly offset within the inner chamber. MECHANICAL. COMPRESSORS Compressors are machines designed to deliver gas at a pressure higher than that originally existing. 17. 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. 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. Transported from colder regions, 2. Prevent possible explosion by relieving pressure caused by fire, coil blockage, or overheating of unit. For the proper functioning of the refrigeration … Natural Cooling : In olden days refrigeration was achieved by natural means such as the use of ice or evaporative cooling. There are various types of compressors used in the refrigeration and air conditioning machines, these are: reciprocating, rotary, screw, centrifugal and scroll. Compressor Types Refrigeration Compressors Figure 4 centrifugal scroll reciprocating helical-rotary Figure 5. FIGURE 7-1 Major Compressor Types Compressors Dynamic Positive Displacement Axial Centrifugal Reciprocating Rotary DYNAMIC COMPRESSORS Dynamic compressors are nonpositive displacement compressors … This compressor wine cooler holds up to 33 standard wine bottles at once and maintains an optimal environment for your most prized vintages.

The basic principle of the refrigerant equipments and the classification of those equipments are discussed here. 145 18 Made during the night by the cooling of water by radiation to the stratosphere. Main types of compressors used in industrial refrigeration are screw, piston, centrifugal and rotary vane. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. The information on the slides is the minimum information that should be explained. 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. 0000001459 00000 n To help you get ahead of the curve, we’ve broken down each one in some summaries below. Liquid passes through expansion device, which reduces its pressure an d controls the flow into the evaporator . 0000004604 00000 n Clipping is a handy way to collect important slides you want to go back to later. In small refrigeration systems the oil is allowed to circulate throughout the whole circuit, but care must be taken to design the pipework and components such that oil can drain back under gravity to the compressor. Types of Refrigeration Vapour Compression Refrigeration Refrigeration cycle Condenser 4 Expansion Device Compressor 3 High Pressure Side. 0000003196 00000 n 0000003709 00000 n Akshay Kr Mishra- 100106039 1. They use compression to raise the temperature of a low-pressure gas, and also remove vapor from the evaporator. 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). Types of Compressor A compressor is a mechanical device that increases the pressure of a gas or air by reducing its volume.

When tank pressure reaches its upper limit the air compressor shuts off. They are one of the best compressor type in rotary compressors.The air is compressed using two spiral elements. 0000000674 00000 n 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. Both of these types of compressors can be single- or multistage. The superheated vapo ur enters the compressor where its pressure is raised . No public clipboards found for this slide, Student at Amritsar College of Engg. Compressor forces more and more air into a storage tank, increasing the pressure. • Centrifugal compressors are essentially large discharge capacity compressors. Rotary Compressors • Rotary compressor function is in which fixed amount of air is displaced with each revolution. Sharda University Thus the need for a shaft seal with the consequent refrigerant leakage problem was eliminated. conditioning can be classified by the type of input energy and the refrigeration process as follows: 1. & Tech, Amritsar.
