This paper presents the detailed laboratory experimental results of a low-temperature Organic Rankine Cycle (ORC) engine coupled with a Reverse Osmosis (RO) desalination unit. In a previous work, the identification of performance of the scroll type expander was presented. At that primary...

Steam traps are essential in the management of steam in industry. Various rating methods of steam-trap types make it difficult to evaluate their performance in a particular steam and condensate system. Table 1 shows steam-trap characteristics and operating conditions that have been rated so far....

Proper selection of a control scenario is essential for efficient management of energy systems which provide space heating and local ventilation to buildings. Using the steady-state, bottom-up approach, we have developed a mathematical model and the software AZMA to analyze the efficiency of...

A study has been carried out on heat recovery from air that ventilates a hot tool in a tool shop. The recovered heat is used to preheat air for space heating of this tool shop. Software has been used to analyze the heat-recovery efficiency and thermal comfort (TC) when the size and temperature...

We use a recovery heat exchanger (RHE) in an industrial building to heat incoming air for space heating by using the heat contents of some of the refuse hot-air flows (RAF). Several RAFs are often available with different flow rates and temperatures. A proper scenario for use of their heat...

The optimal heating-system-retrofit strategy for existing buildings differs due to varying prices of energy, building and installation features, climate conditions, etc. We have examined a test building situated in Linköping, Sweden. By using the OPERA model, we were able to arrive at the...
