Mode of operation of the present invention has following three kinds:

1, new, air draft operational mode

Under this pattern, new wind control valve and air draft control valve are opened, and air-supply blinds and air draft blinds are opened, and return air control valve and return air flame plate are closed, new wind blower fan and air draft fan starting.Outdoor fresh air is taken out by new wind blower fan and is drawn, enter casing by the blinds of decorating outer baffle top, flow through corresponding air flow channel, enter the fresh flue in the square heat recovering heat exchanger, carry out heat exchange with indoor air draft, outdoor air is cooled (summer) or heats (winter), opposite side from correspondence flows out afterwards, flow into the cooling heat(ing) coil again, further cooled off (summer) or heating (heating) here by coil pipe, (0.1～0.3m/s) delivers to the room to air-supply blinds by lower box, and the room is carried out replacement aeration with very low wind speed then.With the processing procedure while of new wind, indoor air draws down taking out of air draft blower fan, enter the preceding exhausting duct of recovery in the casing, enter the air exhaust passage of square heat regenerator then, the new wind of crossing with mutual isolation cross-current carries out heat exchange, the cold of room air passed to new wind (summer) or with the new wind of heat transferred (winter) of room air, flow into exhausting duct after the heat exchange, draw by taking out of air draft blower fan, flow through exhaust outlet, the air draft control valve flows out casing, the air draft airflow strikes changes direction and flows out from the bottom of outer decoration baffle to the bottom of outer baffle.

Under this method of operation, the air of house interior dirt is discharged, additional ozone is come in, at first reclaim 70-80% energy in the air draft by heat regenerator, handle by the further cooling dehumidification (summer) or the heating (winter) of coil pipe afterwards, send into the indoor replacement aeration that carries out with very low wind speed, play the effect that improves indoor air quality, saves energy.

2, free convection operational mode

Under the free convection pattern, new wind control valve and air draft control valve are closed, and the air draft blinds is closed, and air-supply blinds and return air flame plate are opened, and new wind blower fan and air draft blower fan are out of service, and the return air control valve is opened.In summer, coil pipe cools off ambient air, cold air density is big, sedimentation downwards, air-supply blinds by the casing bottom surface flows into indoor, hot-air in the room replenishes inlet body inside from the return air flame plate of casing upper surface simultaneously, is cooled off by coil pipe again, carries out replacement aeration by free convection cool room air so again and again.In the winter time, coil pipe is with its ambient air heating, hot-air density is little, buoyance lift makes progress, return air flame plate by the casing upper surface flows out, indoor colder air is heated by coil pipe again by the additional inlet body of the air-supply blinds of casing lower surface, by free convection air in the room is heated so again and again.

Under this operational mode,, utilize the cold light characteristics of reheating of air in the mode of free convection the room to be cooled off and heat by the cooling and the heating of coil pipe.In summer, because air-supply is by buoyancy-induced fully, send into the room with very low speed, can reach the effect of replacement aeration equally; Can produce the add thermal effect identical in the winter time with the ordinary hot water radiator.Because blower fan does not rerun, meeting is the economy system energy consumption more.

3, radiation heat transfer pattern

Radiation heat transfer pattern and the above two patterns are separate, can be used in combination.Under this pattern, radiant coil is with radiant panel cooling (summer) or heating (winter), because radiator inside is vacuum state, is cooled or mode that the radiant panel that heats can only be by radiation and indoor environment and personnel carry out heat exchange.

The present invention is installed in each room independently near on the body of wall on ground, can be in fully air draft, send under the pattern of new wind and work fully, avoid the cross-infection of each space air pollutant and the accumulation of house interior pollutant, greatly improved air quality.The heat regenerator of inside of the present invention can directly recover energy from air draft, adds the operational mode with free convection, must have obvious energy-saving effect.Simultaneously, the present invention separates the function of traditional air-conditioning cooling dehumidification, bear indoor sensible heat load by radiators, remove indoor humidity load by the new wind of permutation ventilator section processes, guarantee indoor air quality simultaneously, increased pump energy consumption although increased water system, total energy consumption is still far below energy consumption, scavenging efficiency height (0.5-0.67) and the drafting efficiency height (＞100%) of blower fan in the air cooling system.The radiator structure that last the present invention is special makes energy be delivered to indoor with the form of radiation, rather than traditional radiation cooling is carried out the energy transmission with the comprehensive form of convection current and radiation, because the lower radiant panel of temperature does not contact with the room air of high humility, so fundamentally avoided the phenomenon of surface sweating.
