Padhy General Electric C_ompany Appliance Park 5-2North, Louisville, KY 40225 ABSTRACT Energy improvements for a rotary compressor can be achieved in several ways such as: reduction of various electrical and mechanical losses, reduction of gas leakage, better lubrication, better surface cooling, reduction of suction gas heating and by improving other parameters. To have a ' better understanding analytical/numerical analysis is needed. Although various mechanical models are presented to understand the mechanical losses, dynamics, thermodynamics etc.; little work has been done to understand the compressor from a heat uansfer stand point In this paper a lumped heat transfer model for the rotary compressor is described. Various heat sources and heat sinks are analyzed and the temperature profile of the compressor is generated. A good agreement is found between theoretical and experimental results.

Why Does the Wisconsin Boiler and Pressure Vessel Code, 636 41
Why does the Wisconsin Boiler and Pressure Vessel Code, SPS 341, regulate air compressors? By Industry Services Division Boiler and Pressure Vessels Program Almost everyone forms a definite picture in their mind when they hear the term “air compressor.” They probably think of a steel tank of some shape and dimension, with an electric motor, and an air pump mounted on top of the tank. To better understand the requirements of the Wisconsin Boiler Code, SPS 341, pertaining to air compressors, we need to have some common terminology. If a person wanted to purchase an “air compressor” at a hardware or home supply store, they would certainly be offered the equipment described above, consisting of three separate mechanical devices; the motor, the pump, and the storage tank. First, there is an electric motor, used to provide power to the device that pumps air to high pressure. This pumping device is the only part of the unit that is properly called an "air compressor." The compressor delivers high-pressure air to the third and final part of the mechanical assembly, the air storage tank; commonly called a pressure vessel. Because the pressure vessel receives pressurized air, this is the only part of the device described above that is regulated SPS 341. SPS 341 regulates pressure vessels when the pressure vessel's volume capacity is 90 gallons (12 cubic feet) or larger, and the air pressure is 15 pounds per square inch or higher. A typical pressure vessel of this size would be 24 inches in diameter and 48 inches long. In industrial settings, it is common practice to mount very large air compressors in a separate location from the pressure vessels. -

In the typical ARS, a large quantity of high-temperature heat is supplied into the generator, while a substantial amount of low-temperature heat is rejected to the environment from the condenser, it’s a huge waste. In order to decrease the input heat for generator and enhance the performance of conventional ARS, a kind of absorption-compression hybrid refrigeration system recovering condensation heat for generation (RCHG-ARS) was ever proposed. In the present study, the models of both RCHG-ARS and double-effect absorption refrigeration system (DEARS) are established, and the effects of different parameters on them are simulated and compared with each other. As a conclusion, the PEE of RCHG-ARS can be 29.0% higher than that of DEARS, and RCHG-ARS has a wider working conditions than DEARS due to the existence of the compressor. -

ENGINE COOLING and VEHICLE AIR CONDITIONING AGRICULTURAL and CONSTRUCTION VEHICLES What Is Thermal Management?
ENGINE COOLING AND VEHICLE AIR CONDITIONING AGRICULTURAL AND CONSTRUCTION VEHICLES What is thermal management? Modern thermal management encompasses the areas of engine cooling and vehicle air conditioning. In addition to ensuring an optimum engine temperature in all operating states, the main tasks include heating and cooling of the vehicle cabin. However, these two areas should not be considered in isolation. One unit is often formed from components of these two assemblies which influence one another reciprocally. All components used must therefore be as compatible as possible to ensure effective and efficient thermal management. In this brochure, we would like to present you with an overview of our modern air-conditioning systems and also the technology behind them. We not only present the principle of operation, we also examine causes of failure, diagnosis options and special features.

The heat transfer surface of this heat exchanger is composed of polymeric hollow fibers made from polyamide 612 by DuPont (Zytel LC6159). The cross-section of the polymeric radiator is identical to the aluminum radiator (louvered fins on flat tubes) in a Skoda Octavia and measures 720 × 480 mm. The goal of the study is to compare the functionality and performance parameters of both radiators based on the results of tests in a calibrated air wind tunnel. During testing, both heat exchangers were tested in conventional conditions used for car radiators with different air flow and coolant (50% ethylene glycol) rates. The polymeric hollow fiber heat exchanger demonstrated about 20% higher thermal performance for the same air flow.

Sector N: Scrap and Waste Recycling
Industrial Stormwater Fact Sheet Series Sector N: Scrap Recycling and Waste Recycling Facilities U.S. EPA Office of Water EPA-833-F-06-029 February 2021 What is the NPDES stormwater program for industrial activity? Activities, such as material handling and storage, equipment maintenance and cleaning, industrial processing or other operations that occur at industrial facilities are often exposed to stormwater. The runoff from these areas may discharge pollutants directly into nearby waterbodies or indirectly via storm sewer systems, thereby degrading water quality. In 1990, the U.S. Environmental Protection Agency (EPA) developed permitting regulations under the National Pollutant Discharge Elimination System (NPDES) to control stormwater discharges associated with eleven categories of industrial activity. As a result, NPDES permitting authorities, which may be either EPA or a state environmental agency, issue stormwater permits to control runoff from these industrial facilities. What types of industrial facilities are required to obtain permit coverage? This fact sheet specifically discusses stormwater discharges various industries including scrap recycling and waste recycling facilities as defined by Standard Industrial Classification (SIC) Major Group Code 50 (5093). Facilities and products in this group fall under the following categories, all of which require coverage under an industrial stormwater permit: ◆ Scrap and waste recycling facilities (non-source separated, non-liquid recyclable materials) engaged in processing, reclaiming, and wholesale distribution of scrap and waste materials such as ferrous and nonferrous metals, paper, plastic, cardboard, glass, and animal hides. ◆ Waste recycling facilities (liquid recyclable materials) engaged in reclaiming and recycling liquid wastes such as used oil, antifreeze, mineral spirits, and industrial solvents. -

Consumer Guide: Balancing the Central Heating System
Consumer Guide: Balancing the central heating system System Balancing Keep your home heating system in good working order. Balancing the heating system Balancing of a heating system is a simple process which can improve operating efficiency, comfort and reduce energy usage in wet central heating systems. Many homeowners are unaware of the merits of system balancing -an intuitive, common sense principle that heating engineers use to make new and existing systems operate more efficiently. Why balance? Balancing of the heating system is the process of optimising the distribution of water through the radiators by adjusting the lockshield valve which equalizes the system pressure so it provides the intended indoor climate at optimum energy efficiency and minimal operating cost. To provide the correct heat output each radiator requires a certain flow known as the design flow. If the flow of water through the radiators is not balanced, the result can be that some radiators can take the bulk of the hot water flow from the boiler, leaving other radiators with little flow. This can affect the boiler efficiency and home comfort conditions as some rooms may be too hot or remain cold. There are also other potential problems. Thermostatic radiator valves with too much flow may not operate properly and can be noisy with water “streaming” noises through the valves, particularly as they start to close when the room temperature increases. What causes an unbalanced system? One cause is radiators removed for decorating and then refitted. This can affect the balance of the whole system. Consequently, to overcome poor circulation and cure “cold radiators” the system pump may be put onto a higher speed or the boiler thermostat put onto a higher temperature setting. -
A Heat Pump for Space Applications
45th International Conference on Environmental Systems ICES-2015-35 12-16 July 2015, Bellevue, Washington A Heat Pump for Space Applications H.J. van Gerner 1, G. van Donk2, A. Pauw3, and J. van Es4 National Aerospace Laboratory NLR, Amsterdam, The Netherlands and S. Lapensée5 European Space Agency, ESA/ESTEC, Noordwijk ZH, The Netherlands In commercial communication satellites, waste heat (5-10kW) has to be radiated into space by radiators. These radiators determine the size of the spacecraft, and a further increase in radiator size (and therefore spacecraft size) to increase the heat rejection capacity is not practical. A heat pump can be used to raise the radiator temperature above the temperature of the equipment, which results in a higher heat rejecting capacity without increasing the size of the radiators. A heat pump also provides the opportunity to use East/West radiators, which become almost as effective as North/South radiators when the temperature is elevated to 100°C. The heat pump works with the vapour compression cycle and requires a compressor. However, commercially available compressors have a high mass (40 kg for 10kW cooling capacity), cause excessive vibrations, and are intended for much lower temperatures (maximum 65°C) than what is required for the space heat pump application (100°C). Dedicated aerospace compressors have been developed with a lower mass (19 kg) and for higher temperatures, but these compressors have a lower efficiency. For this reason, an electrically-driven, high-speed (200,000 RPM), centrifugal compressor system has been developed in a project funded by the European Space Agency (ESA). -
