摘要:
A detection circuit includes a first power line, a first signal conditioning module operationally coupled to the first power line, a neutral line (N) operationally coupled to the first signal conditioning module, a second signal conditioning module operationally coupled to the first power line, a second power line operationally coupled to the second signal conditioning module, and an analog to digital (A/D) converter operationally coupled to the first and the second signal conditioning modules.
摘要:
An electric heating module for a room air conditioning system and methods are presented in which the duty cycle of the electric heater banks are controlled to limit the inrush current during the startup phase of the heater or to supplement the heat generated by the heat pump when the heat capacity of the heat pump nears the heat loss of the room being heated.
