The interior member includes a base material part and a skin part disposed on one surface side of the base material part. The skin part is provided with an air passage part through which air that is temperature-adjusted to a predetermined temperature passes. The air passage part has a passing resistance member (a knitted fabric part that gives passing resistance to the air passing through the air passage part. Also, the air that is temperature-adjusted may be distributed from air sent out from an air conditioner installed in a vehicle, a building, or the like. Further, examples of the passing resistance member include three-dimensional knitted fabrics (such as a double raschel knitted fabric or a circular knitted fabric) and nonwoven fabrics.

Electric Generator/Energy Efficiency Air conditionerThe device is a way to create the pressure needed to spin a turbine to efficiently use and generate electricity. The device is an advancement in energy efficiency. The device uses the conversion process by converting liquid 410-A (refrigerant) into its vapor form to generate the pressure and volume needed to spin a turbine, and then be recycled back by being recompressed into liquid form to begin the process over in an endless loop using an alternating multiple tank configuration. The device uses the energy it produces to power an energy efficient A/C that has a system of using its conversion process to spin a small turbine to subsidize its energy consumption without affecting the required pressures to operate an air conditioner. The system integrates the power grid, solar power/small battery bank, and the 410-A phase conversion process to efficiently use and generate electricity for the purpose of powering an energy efficient air conditioner.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

An air conditioning system includes an outdoor air latent cooling treatment stage providing parallel airflow with a return air sensible cooling treatment stage. A mixer mixes the treated outdoor air with the return air to form the conditioned space supply air. A first relative humidity controller monitors the outdoor air relative humidity and separates the outdoor air from saturation to maintain relative humidity in outdoor air ducting below a predetermined mould growth limit. A second relative humidity controller monitors the conditioned space supply air relative humidity and separates the space supply air from saturation to maintain relative humidity in space supply air ducting below a predetermined mould growth limit. The outdoor air latent cooling treatment stage includes a dehumidification heat exchanger, combination pre-cooling and heat reclaim heat exchangers, or a heat transfer pump. The return air sensible cooling treatment stage includes at least a sensible cooling heat exchanger.

Presented is a simple, but highly energy efficient industrial heating device and method for rapid heating and high temperature gradient production whereby fermions and bosons are introduced into an adjoining fluid which may be boundary layered and consequently produce an amplifiable activated condition even at room pressure and high temperature. This heating device uses a comparatively long current carrying member which may have some curvature with penetration of the current carrying members into spaces that could have any cross-sectional geometry in a high temperature resistant stable material.
