1. Principles and methods
It uses the low temperature and high temperature storage hot trough, according to the movement need, uses the cylinder valve to switch the cold and hot air, thus achieves the fast temperature impact effect, balances the temperature control system (BTC) + the special design supply air circulation system, controls the SSR by the P.I.D. method, causes the heating amount of the system to be equal to the heat loss, therefore makes it long-term stable use.
2. Main Parameters
