Refrigerator standards and their impact on United States society

by Inderscience Publishers  (Apr. 28, 2014)

This paper addresses criticisms of US Federal appliance efficiency standards and whether or how the imposition of efficiency standards on household refrigerators and freezers in the US affects prices, supply, and various other attributes. The study is based on historical data about changes in standards for household refrigerators along with data ...

Refrigerator condenser (shell and tube heat exchanger) cleaning case study

by Mibo International Corp.  (Nov. 22, 2013)

In today's industrial environment of unceasingly consummates and improvement of equipment manufacturing technologies, heat-exchange and water circulation equipments become popular in the manufacture industry. The equipments can run efficiently at rated power if their systems have clean and unimpeded water channel. Once the water running equipments ...

Leaking Refrigerators - Sorted

by Cleveland Biotech Ltd  (Mar. 1, 2011)

FridgeFree has been proven to eliminate the problem of leaking refrigerators by eradicating the gel that blocks the drain pipes leading to the floods.

Thermodynamic analysis of a hybrid gas turbine/thermoacoustic heat pump/refrigeration engine

by Inderscience Publishers  (Nov. 4, 2014)

Possible performance enhancement of small gas turbine power plants through the application of thermoacoustic systems is examined. The thermoacoustic subsystem is powered only by the waste heat of the gas turbine. Two different gas turbine configurations are considered: a Thermoacoustic refrigerator assisted gas turbine (TRG) and a Combined ...

Walk-in refrigerators and freezers at a Prestigious hotel

by Power Knot LLC  (Dec. 14, 2012)

The Mark Hopkins Hotel in San Francisco is one of the most prestigious hotels in the city. It takes pride in the care and comfort of its guests. The refrigeration systems keep food cold or frozen. These are critical components of the hotel’s food service and it is paramount that no system be taken out of service. With a view to becoming ...

Thermo-ecological performance optimisation of two stage irreversible refrigerators

by Inderscience Publishers  (Mar. 23, 2009)

The present study investigates the optimal performance of two stage refrigeration system based on thermo-ecological performance criterion. To maximise the ecological performance function, the working fluid temperatures are optimised. The optimal conditions such as cooling load, entropy generation rate and Coefficient of Performance (COP) are ...

Optimisation of an irreversible Carnot refrigerator working between two heat reservoirs

by Inderscience Publishers  (Dec. 2, 2009)

A model of finite-resources optimisation for irreversible refrigerators is presented in this paper. An irreversible Carnot refrigerator operating between two heat reservoirs is analysed. Several important optimum results, subject to different resource constraints have been obtained. The relations among these results are also discussed. The results ...

Energy and exergy analysis of reverse Brayton refrigerator for Gas Turbine power boosting

by Inderscience Publishers  (Mar. 23, 2009)

In this study the use of Reverse Brayton cycle to boost up the power of gas turbine power plants operating in hot humid ambiance is analysed by the energy and exergy methods. The gas turbine inlet temperature is reduced by mixing the chilled air from Brayton refrigeration cycle and the main intake air stream reaching low intake temperatures. In ...

Realistic limitations to the operation of heat-driven refrigerators

by Inderscience Publishers  (Jan. 17, 2007)

The optimal characteristic curve relating the COP and the refrigeration rate of an irreversible heat-driven refrigerator is established on the basis of a thermodynamic model which combines the endoreversible model and the heat leak insulation model. It is found that the curve is loop-shaped and that both the refrigeration rate and the COP exhibit ...
