Energy efficient hvac system with variable capacity start up control

A control system for an energy efficient heating, ventilation, and air conditioning (HVAC) system, wherein the control system comprises:

• processing circuitry;
• and
• non-transitory, machine-readable-media comprising instructions stored thereon that, when executed by the processing circuitry, cause the processing circuitry to:
• receive data indicative of a temperature within a conditioned space;
• receive data indicative of a set point temperature of the conditioned space;
• determine a deviation between the temperature and the set point temperature;
• initialize operation of a compressor of the energy efficient HVAC system at an intermediate capacity of a plurality of operating capacities of the compressor;
• and
• maintain operation of the compressor at the intermediate operating capacity in response to a determination that the deviation is equal to or less than a threshold difference value.

An energy efficient heating, ventilation, and air conditioning (HVAC) system, comprising:

• a controller configured to:
• receive a call for conditioning;
• initialize operation of the energy efficient HVAC system at an intermediate operating capacity of a plurality of intermediate operating capacities in response to receipt of the call for conditioning;
• receive data indicative of a set point temperature of a conditioned space from a thermostat of the energy efficient HVAC system;
• receive data indicative of a temperature within the conditioned space from a sensor of the energy efficient HVAC system;
• determine a deviation between the temperature and the set point temperature;
• compare the deviation to a threshold difference value;
• and
• maintain operation of the energy efficient HVAC system at the intermediate operating capacity for a predetermined period of time in response to a determination that the deviation is equal to or less than the threshold difference value.
