Purpose of the development: Heat recovery ventilation air is used for ventilation, while providing full energy saving. They are used to provide effective ventilation and energy-saving fresh air and removal of contaminated without violating thermal comfort indoors.

Recommended application field: Application recuperators TeFo advisable in all the areas where modern high-density windows and doors and special precautions are taken to ensure the forced ventilation.

Technical characteristic: Tests have made it possible to clarify the mathematical model and based on this to create a standard series , which includes four basic models of heat exchangers ( with the ability to control performance within the operating range of each heat exchanger ) TeFo 1 - designed for forced ventilation in the range of 35-37 cu.m / h TeFo 2 - in the range of 39-41 cu.m / h TeFo 3 - in the range of 90-105 cubic meters / h TeFo 4 - about 130 cbm / h Electric power consumption is 6.12 W, while saving in the average winter mode power 360-1050 W , respectively , ie energy-saving effect is characterized by the ratio 60-87 times .

Advantages over analogues: Benefits recuperators TeFo : - High degree of recovery , confirmed by two series of tests in a climate chamber akrreditovannogo State Standard of Ukraine KievZNIIEP test center . - Self-cleaning effect , providing constantly clean state surfaces along which moves into the room air , and the absence in most cases the liquid phase from the exhaust air . - Structurally allow remote condensing heat exchanger in the case of the conditions under which it is not excluded the formation of the liquid phase. - A uniform velocity profile throughout the supply air path that eliminates dead zones in which could create conditions for the development of micro-organisms harmful to humans . - Structurally secured hermetic separation of the incoming and outgoing streams of air, excluding guaranteed their interpenetration . - Direct the recovery of the time . - Design of the housing Multivariance exchanger that provides ease of adaptation to a specific location and method of installation ( in the thickness of the wall , in a window escarpment in podokonnoj niche behind a false ceiling , etc.). - Possibility of a heat exchanger in the basic version to serve two adjacent rooms. - Unlimited lifetime of the main ( as a matter of fact , and value ) exchanger element - the warranty period for the heat transfer element 100 is let.Srok service exchanger assembly ( except easily replaceable fans) exceeds the lifespan of buildings - the life of the heat exchanger 50 years after which may need replacement plastic housing elements . - Ability to perform only the intended heat exchanger maintenance - change fans - by the consumer, and without dismantling the heat exchanger . - Ability to carry out , if the need arises , both mechanical and chemical cleaning of the inlet air tract , including s.primenenie all known detergents and disinfectants . The quality of the purification can be monitored visually. - The efficiency of the heat exchanger in an extremely wide range of ambient temperatures - from -50 ° C to +80 ° C

The development stage readiness: Introduced in production

Technical and economic effect: Recovery of the (energy saving) TeFo using recuperators is not less than 75%. In the case of energy recovery data at the design stage, they pay for themselves before the start of field installation by reducing the required power of the heat source and the corresponding reduction in price of building systems that maintain temperature.

Description of the development:
()
Heat recovery developed and released on the basis of heat exchangers TTAI . Recuperator has two low-noise fans and designed as a parallelepiped or cylinder within which the system is located in a special way shaped tubes. Room air is forced through the heat exchanger one fan , and air from the street - the other. Thus one air flow through the walls of the tubes gives heat to another ( winter heated air from the street , and in the summer , when air conditioners work , cooled ) . Exchanger can be mounted either directly on the wall or in a specially niches in the wall ( in this case there is an option arrangement recuperator housing perpendicular to the plane of the wall) , or as a separate element of interior space (for example , being designed as a decorative pilasters ) , etc. In this provides energy saving, comfortable temperature conditions and sanitary standards prescribed levels of ventilation .
