Contracting chamber has the characteristics that more efficient reliable.Theoretically, if wanting to obtain optimal increasing enthalpy tonifying Qi effect, different operating conditions are corresponding different
Best increasing enthalpy tonifying Qi position, tonifying Qi positional structure should adjust accordingly with operating condition.But it can only be used in production application a certain
Fixed tonifying Qi position meets nominal design operating condition, therefore, in the practical application of compressor, system increasing enthalpy superfeed pressure and pressure
The pressure of contracting chamber cannot correspond to very well, cause to compress cavity pressure under certain operating conditions during tonifying Qi to be more than that extraneous tonifying Qi increases
Enthalpy pressure, from compression chamber, adverse current, increasing enthalpy tonifying Qi effect into tonifying Qi pipeline are greatly reduced or even are done without effect, shadow to refrigerant
Ring application of the increasing enthalpy technology in screw compressor.Common design is arranged unidirectionally between increasing enthalpy tonifying Qi pipeline and compression chamber
Non-return structure closes the circuit in the case where adverse current occurs in time, the external leakage that freezes in compression chamber is prevented, so as to significantly mention
Enthalpy-increasing effect under such high operating condition.It is complicated to analyze existing scroll compressor structure, adverse current effect, needs normal in order to prevent
Many additional structures are added in rule structure, and to eventually lead to more complicated compressor arrangement, compressor size and weight bigger.It can not
Meet more use environments.
