Piezoelectric blower piloted valve

This disclosure describes systems and methods for piloting a pneumatic valve using one or more piezoelectric blowers. According to embodiments, the one or more piezoelectric blowers may be coupled to the pneumatic valve to form a small, light-weight pneumatic valve that may be placed proximal to a ventilated patient, e.g., at the patient wye or the patient interface. Due to the close coupling of the one or more piezoelectric blowers, the pneumatic valve has a substantially shorter response time than traditional pneumatically piloted valves. Moreover, when piezoelectric blowers are coupled to the pneumatic valve in parallel, response time may be further decreased. Additionally or alternatively, when piezoelectric blowers are coupled to the pneumatic valve in series, pilot pressure may be increased as a function of the number of piezoelectric blowers in the series.

Ventilation device

The invention discloses a ventilation device, which aims to solve the problem that the conventional ventilation device does not have an air adjusting function. The device comprises a pedestal, a high-speed air blower and an annular ejector, wherein the high-speed air blower is arranged at the bottom of the pedestal; the annular ejector is arranged at an air outlet of the high-speed air blower and is fixed on the pedestal; and the air inlet or the air outlet of the high-speed air blower is provided with a vapor generator which is fixed on the pedestal for producing water vapor. In the ventilation device, the water vapor is produced through the vapor generator and is ejected through an atomization nozzle at a high speed to produce fog of smaller granularity, so that a hot air flow can more easily absorb the latent heat of vaporization, and the ventilation device has a humidification effect and a heat absorption and temperature reduction effect on a large amount of hot air sucked by the annular nozzle, and brings comfortable cool air similar to air on the shore of a lake or a sea to the surrounding environment. In the ventilation device, an external circulating device is not required to be mounted, so the cost is low; the space is not required to be closed, so that air convection is guaranteed; and the ventilation device is more energy-saving in the same temperature reduction range compared with a fan and an air conditioner, and can be used conveniently and safely.

Methods of Optimizing Vehicular Air Conditioning Control Systems

Air conditioning system controls are optimized for an air conditioning system having a compressor in IC engine vehicles and in hybrid or fuel cell vehicles having electric drive motors by first determining the operating temperature of at least one of the following vehicle components: engine coolant and transmission oil for all types of vehicles, and for hybrid or fuel cell vehicles also determining the operating temperature of inverter coolant and the electric drive motors. At least one operating temperature is then compared to lower and upper temperature limits. If the operating temperature is outside of the temperature limits air conditioner heat load is reduced by at least one of the following steps: increasing cabin air recirculation, reducing cabin blower speed and reducing air conditioner compressor capacity. Subsequent to reducing air conditioner heat load, selected operating temperature or temperatures are monitored to determine if the operating temperature exceeds the upper temperature limit or limits. If the operating temperature or temperatures exceed the upper limit or limits the compressor is shut off.
