摘要:
A smart HVAC system includes a plurality of sensors that monitor the temperature and humidity of a conditioned space and the energy efficiency of the HVAC system. A system controller is operable to control one or more bypass dampers. The modulation of air volume allows the cooling coil to achieve an optimum BTU extraction rate, and regulate temperature and humidity levels of the conditioned space. Sensor data is interpreted by a controller to modulate positioning of the dampers, thereby regulating the volume of air moved across the cooling coil. The smart HVAC system regulates the amount of air moved over the coil according to the desired system output, which includes temperature humidity and energy efficiency while maintaining a constant movement of air and the optimal amount of air exchanges per hour throughout the conditioned space with enhanced dehumidification and mold free systems.

An air-conditioning control apparatus controlling a plurality of air conditioners calculates an adjustment time for adjusting a temperature of an area to be adjusted by the air conditioners to be controlled to between a desired temperature and an allowable temperature, generates a control schedule based on the adjustment time, and controls the air conditioners with the generated control schedule, instead of controlling with a preset stop time which is fixed, in order to bring the temperature around the air conditioners to the desired temperature. Thus, the air conditioners can be made to stop heat exchange before the desired temperature is reached, so that power consumption can be reduced.

An air conditioning control system which is provided in a vehicle includes an air conditioning device and a controller. The controller is configured to acquire vehicle outside humidity information representing humidity when a start switch of the vehicle is turned on, execute outside air introduction processing for making an outside air introduction ratio of the air conditioning device greater than 0% in an off state of the start switch, and when a first condition that the outside air introduction processing is executed is satisfied, calculate vehicle inside absolute humidity of the vehicle in an on state of the start switch with absolute humidity based on the acquired vehicle outside humidity information as an initial value.

A battery pack is provided. The battery pack includes first and second temperature sensors that are disposed in first and second interior spaces, respectively. The first temperature sensor generates a first signal indicative of a first temperature level of the battery cell. The second temperature sensor generates a second signal indicative of a second temperature level of the DC-DC voltage converter. The battery pack further includes a microprocessor that determines a first fan speed percentage value of the electric fan based on the first temperature level, and a second fan speed percentage value of the electric fan based on the second temperature level. The microprocessor selects the first fan speed percentage value if the first fan speed percentage value is greater than the second fan speed percentage value.

Systems and methods are described for controlling fan-only cooling duration following normal air conditioning operation. Following normal AC cooling, economical fan cooling is used. The duration of the fan cooling period is adjusted based on temperature measurements made during the previous cooling cycle that ended with fan cooling. An expected temperature drop to be provided by fan cooling as well as an expected time to achieve that drop is calculated based on prior measurements. The expected values are then used improve fan cooling for subsequent cooling cycles. In some cases, fan cooling is not initiated unless: (1) a time limit has an elapsed, such that sufficient condensation is allowed to form on the evaporator coil during the first phase, and (2) indoor relative humidity is below a predetermined threshold.

A combined heating, ventilation, air conditioning, and refrigeration (“HVACR”) system including an HVAC sub-system and a refrigeration sub-system. The HVAC sub-system is in communication with an open space of an indoor environment and includes a first condenser, a first evaporator, and a first compressor at least partially defining a first refrigerant circuit circulating a first refrigerant for selectively conditioning an airflow within the HVAC subsystem that conditions the open space. The refrigeration sub-system is in communication with an enclosed space within the indoor environment and includes a second con-denser, a second evaporator, and a second compressor and at least partially defining a second refrigerant circuit circulating a second refrigerant for selectively conditioning the enclosed space. Heat from the second refrigerant is selectively transferred to the airflow within the second condenser to reheat the airflow prior to the airflow being discharged into the open space.
