ABSTRACT:
A residential HVAC system includes a heat pump having a compressor arranged to heat a domestic hot water vessel and to heat or cool a storage vessel which is connected to a heat exchanger within the residence. Temperature sensors are provided at critical locations throughout the system and current and voltage sensors are coupled to the power lines feeding the residence. A microprocessor controls the operation of the compressor and other components of the heat pump system in response to measured temperatures, in response to the level of energy supplied to the residence and in response to the existence of on- or off-peak time intervals to operate the compressor and/or resistive heating elements to condition the hot water and storage vessels for subsequent use and to control an interior fan to condition the space. Operation of the compressor is controlled during on-peak intervals as a function of the resident's life style as reflected in power usage and requested comfort level.
