To solve their undesired frosting problem, reverse cycle defrosting is always employed.
For an air source heat pump (ASHP) unit, reverse cycle defrosting operations are always conducted to solve the undesired frosting problem.
Air source heat pump (ASHP) units are widely used in recent years, and reverse cycle defrosting becomes the most popular method to solve their undesired frosting problem.
The basic idea behind computational heuristics is that rules can be identified that serve as guidelines for finding a solution to a given problem quickly and efficiently by avoiding undesired states of the problem space.
Theoretically, hydrodynamic bearings are designed for infinite life, but the precision machining, heating or misalignment with the rotor can contribute to performance problems and undesired wear.
As a consequence, the location of critical points of the poloidal flux, that are of paramount importance in tokamak engineering, is constrained to nodes of the mesh leading to undesired jumps in transient problems.
However, the clinical application of the current antimitotic drugs is hampered by the problems of undesired side effects, poor pharmacokinetic properties, complex chemical structures, and emerging drug resistance [ 24].
Our finding seems to eliminate the previous uncertainty and excessive caution in using hormonal contraceptives which often mean exporing NF1 patients to more severe problems as undesired pregnancies with important effects on tumoral growth.
