  • Publication number: 20210231325
    Abstract: A multifunction adaptive whole house fan system can include a whole house fan to pull large volume of air through a building structure. The whole house fan can pull air from a window or damper into the building structure and expel air through an attic. The system can monitor the environment to operate the whole house fan when desired conditions are present in coordination with other systems of the building structure to reduce overall energy consumption.

  • Publication number: 20210156582
    Abstract: A fresh air cooling and ventilating system can include a whole house fan for introducing fresh air into a building structure. The fresh air cooling and ventilating system can include a whole house fan and/or a controller. The controller can be operably in communication with an air conditioning system and coordinate the usage of the fresh air cooling and ventilating system and the air conditioning system to reduce overall energy consumption. The system can be automated to run with no or minimal user input.

  • Patent number: 10890523
    Abstract: An optical spectrometer module for analysing samples. The optical spectrometer module comprises two or more sample holders. Each sample holder is adapted to receive and reproducibly position a sample in fixed locations within the optical spectrometer module. Each sample holder is also adapted to receive a light beam to thereby enable a sample contained in the sample holder to be exposed to the received light beam. Each sample holder is further adapted to enable light transmitted through the sample holder to exit the sample holder. The optical spectrometer module also comprises two or more electro-thermal components. Each electro-thermal component is thermally coupled to a respective sample holder to control the temperature of the sample holder.

  • Patent number: 10830464
    Abstract: A fresh-air cooling system for a building structure having an unvented attic is provided. The system provides airflow pathways that allow outside air to be drawn through, and discharged from, a building having an unvented attic. Dampers with a low thermal conductivity regulate airflow through the building structure. The system allows a whole house fan to cool a building having an unvented attic. The system seals or otherwise alters airflow pathways through the building structure in order to reduce heat transfer between the building and the outside environment when the cooling system is not in use.

  • Patent number: 10753627
    Abstract: An energy efficient and quiet air cooling system for a building structure is provided. The air cooling system includes an evaporator system mounted in the wall of the building, a remotely mounted fan, an air intake, and a sound and heat insulating duct. The fan is mounted in the attic and configured to draw air from the living area of the building through the sound insulating duct with sufficient power to create a negative static pressure in the living area. The negative static pressure in turn causes outside air to flow through the evaporator system which removes heat from the outside air. The cooled air is in turn drawn into the building and pulled into the attic through the duct and expelled through the attic. The fan expels warm air into the attic, creating a positive pressure environment which causes the warm air to be expelled from the attic through natural vents.

  • Patent number: 7497774
    Abstract: A whole house fan system and installation methods configured to reduce noise generated by the fan are provided. The system generally includes a fan, a register, and a flexible duct extending between the fan and the register. The flexible duct has acoustical insulation properties, which helps to reduce sound transmission from the fan to the register. The fan system is configured to be mounted in the attic space of a house. The fan motor is suspended in the attic so that it does not have direct contact with any part of the building structure.

  • Patent number: 7214934
    Abstract: A RF power generator for exciting inductively coupled plasma for spectrometry includes an induction coil for exciting the plasma as part of its load circuit. The load circuit also comprises a capacitor connected in parallel with the induction coil. The RF power generator is a free running oscillator having a switching circuit of two MOSFETs alternately switchable on and off via a feedback control circuit from the load circuit. RF power from the switching circuit is coupled to the load circuit via an inductor. The inductor and load circuit is resonant at a first frequency, which is lower than the operating frequency of the power generator.
