Abstract
Embodiments include systems and methods for heating water and cooling air simultaneously, as well as other simultaneous heating and cooling operations. An example variable refrigerant flow conditioning system includes an outdoor unit having a compressor, a condenser coil, and a fan, a water heater coupled to the outdoor unit, a first air conditioning unit coupled to the outdoor unit, and a controller. The controller may be configured to determine that a cooling operation mode is active during a first time interval, cause vapor refrigerant to be directed from the outdoor unit to the water heater and liquid refrigerant to be directed from the outdoor unit to the first air conditioning unit, determine that a heating operation mode is active during a second time interval, and cause the vapor refrigerant to be directed from the outdoor unit to both the water heater and the first air conditioning unit.
