The centralized heating system generally uses central heating facilities such as boiler room and heat exchange station to supply heat energy to multiple users. It usually requires a long heating network pipeline, which has certain transmission losses and is not flexible enough to adjust according to ...

In order to explore the formation mechanism and influencing factors of the temperature difference between two ends of the plate stack, an expression of the temperature change of the stack with time was established based on the two-dimensional heat conduction equation. Based on this, the finite ele...
Semi-hermetic refrigeration compressor adopts a structure of crankcase-integrated cylinder block. The motor shell is an extension of the crankcase to reduce the connection surface and ensure the concentricity between the compressor and motor. The crankcase and the motor room are connected by holes to ...
The nutrient solution is supplied by a peristaltic pump and permeates from the lumen-side to the shell-side of the MGR. The microorganism is immobilised on either the lumen-side or the shell-side of the MGR. Humidified air is supplied on the shell-side, and two pressure transducers are ...

The heated fluid is used in various applications including water heating, central heating, cooking, etc. Subcritical and supercritical boilers are such steam generating systems. The key difference between a Subcritical and supercritical boiler is that Subcritical boilers work at a subcritical pressure of...
I N Suamir [13] simulated and optimized chilled water circuit system of a central air conditioning plant applied for a five-star hotel. Thermodynamic analyses and numerical simulations were established to evaluate chilled water flow rate. Optimization on the chilled water flow rate between primary ...
