Abstract: An improved HVAC system is provided for the delivery of a temperature controlled air supply via one or more air curtains provided at windows, doors and walls. The air curtains create a double layer of insulation over the surface of a window, door or wall. The invention provides for the use of the temperature controlled air flow from the air curtain to directly affect the interior room temperature. The invention provides an improved system for continuous cleaning the recycled air through the use of a wet electrostatic precipitator in the HVAC air flow, as well as providing a higher speed mode for the air curtain to prevent the inflow of particles and contaminants from outside of the building, when windows or doors are open. The invention may be installed on existing construction, or incorporated as part of new construction.

Abstract: A method of pick-up of soiled laundry and dry cleaning and re-delivery of the same after washing and dry-cleaning at a remote servicing site. The method includes providing a pick-up and delivery vehicle proximal to the location of the customer for a set range of time and date. The vehicle is provided with a laundry scale and an invoice printer/generator so that the customer receives an invoice at the site where the customer drops off his/her soiled laundry. The invoice lists the quantity of soiled articles, the anticipated cost of the services, and the date, time and location for pick-up of washed/dry cleaned articles. Upon delivery of the laundered garments, the client pays for the services and receives the indicated and invoiced, now laundered articles.
