Hot air is generated by passing ambient air through the heat exchanger. Three different types of heat exchanger viz. type-I, type-II and type-III have been used. The height of the heat exchangers has been varied from 1050 mm to 1800 mm to evaluate the effect of height variation on the...

Heat exchangers are used to heat or cool products in the food, dairy, chemical and pharmaceutical industries, among others. Many different types of heat exchangers are available, and they often are interchangeable for a given application. For example, in a chemical processing operation, one plant...
This paper presents an experimental and numerical study of the results of a thermal performance test using precast high-strength concrete (PHC) energy piles with W and coil-type ground heat exchangers (GHEs). In-situ thermal performance tests (TPTs) were conducted for four days under an intermi...
finned tube heat exchangerIn order to enhance the heat recovery efficiency and net energy consumption ratio of the run-around heat recovery system applied in gas and oil field and other buildings, this study replaces the conventional heat exchangers with wavy fin tube heat exchangers, slotted fin...
This study presents the experimental results for the first time use of Al2O3/ethylene glycol-water (EG-water) nano-fluid (NF) in ground heat exchangers (GHE) within the ground source heat pump (GSHP) system which is prepared with 8nm γ -Al2O3 nanoparticles. A test room with an area...
On the contrary, When β > 40°, the rectangular duct has a better performance than that of trapezoidal ducts. The applicability of the above conclusions is proved by using the taguchi method. Introduction Ducts with rectangle shapes are commonly used in various heat exchangers. The rectangle ...
Different authors have suggested different cascade heat exchangers for ARC refrigerators. There is no study in literature that suggests at what temperature ranges one, two or three cascade heat exchangers are necessary. In this paper the performance of an ARC refrigerator operating in the liquid ...

aHowever, typical values of heat transfer and fouling coefficients for different fluids are available in the literature and can be used as initial guesses [4,21,22]. Furthermore, the system must satisfy the equation governing heat exchangers, defined as: 然而,热传递和弄脏系数的典型的价值为不同...
