Combined chiller and boiler HVAC system in a single outdoor operating unit

Abstract

A combined chiller-boiler HVAC system which integrates all operating components including the boiler, chiller, distribution pumps, condenser coils, condenser fans and controls onto one single enclosed platform built for installation exterior to the structure being served and designed to produce heated or cooling fluid sequentially or simultaneously in differing areas of a building on demand. This system utilizes both air and water cooling whereby waste heat absorbed during a water cooling cycle, can be captured and re-directed for other uses.

1 . A hydronic combined heating and cooling HVAC system mounted on a platform wherein all the principle operating components and controls are combined into one programmable pressurized efficient operational unit for installation exterior to the structure being served. 
   
   
       2 . A hydronic combined heating and cooling HVAC system mounted on a platform wherein the principle operating components are compartmented into areas appropriate to their functional purposes of a negative pressure condenser cooling chamber, a positive pressure boiler chamber, an isolated electrical chamber, and a separate pump chamber. The integrity of air pressures in the chambers is preserved under maintenance conditions through the use of external test ports that eliminate the need to remove any enclosure panels. 
   
   
       3 . A hydronic combined heating and cooling system mounted on a platform wherein each separate compartmented functional area is individually accessible for service without disturbing any other functional area including testing of the chiller operation 
   
   
       4 . A hydronic combined heating and cooling system whose compartmenting arrangement is not necessarily restricted to the current juxtaposition of the principle operating components as long as the positioning of the components maintain their appropriate functions and maintain the serviceability. 
   
   
       5 . A hydronic combined heating and cooling system that can be programmed to deliver heating or cooling sequentially or simultaneously to different areas or rooms in the same structure. 
   
   
       6 . A hydronic combined heating and cooling system designed for all weather installation exterior to the structure it serves suitable for ground mounting, roof mounting and sub-grade mounting provided the appropriate clearances around the unit are maintained. 
   
   
       7 . A hydronic combined heating and cooling system that removes condenser heat by using water, air or both and when using water can recover waste heat and convert that heat to useful purposes such as heating a swimming pool, a spa or potable water.
