Convenience stores with refrigerated display cases are ubiquitous in much of the developed world. For such buildings it is common to utilize multiple rooftop units (RTU) to serve the retail area and multiple coolers or freezers to provide cooling for merchandise. The overall objective of this paper is to develop and assess an integrated control approach for typical convenience store application...

As refrigeration compressor manufacturers introduce machines with improved efficiencies there is a need for updating performance data. The compressor performance data which is published should be a true representation of the actual compressor performance, historically this has resulted in lengthy test programmes for the compressor manufacturer. A system is required which can accurately produce ...

a refrigeration cycle is a chain of various pieces of equipment including compressors, condensers, evaporators, and expansion devices each of which takes on a particular thermodynamic process duty in the cycle that eventually results in the production of the required refrigeration. the results of optimized mixed refrigerant cycles (mrcs) in part i show that the configuration of mrc is an effect...

The commercial food sector, including agriculture, food manufacture transport and retailing is responsible for 22% of the UK’s total greenhouse gas emissions. Food distribution and retail accounts for approximately one third of this, with food transport which includes motive power and refrigeration estimated to be responsible for 1.8 % of total emissions [1]. Road transport refrigeration equipm...

In this paper a new computer code, Mpower, recently developed between Universidad Politécnica de Valencia and Modine Manufacturing Company is presented. Mpower is based on a long experience on the detailed modeling of refrigeration components and is fully targeted to assist the design of components and systems, especially envisaged from the beginning of its development as a design tool for indu...
