Embodiment

[0067] Use PEMFC to provide fresh air purification, dehumidification and humidification process required electricity and heat required for regeneration of solid adsorbents; PEMFC electricity is mainly used for fans of ventilation ducts, water pumps for cooling water circuits, and motors that control the rotation of shafts. At the same time, the heat generated is sent to the waste heat exchanger side in the ventilation pipeline through the cooling water to heat the air passing into the fresh air dehumidifier.

[0068] Use the waste heat of PEMFC to regenerate the adsorbent; the waste heat of PEMFC is taken away by the cooling water, and the two waste heat heat exchangers can be respectively connected by switching the valves on the two cooling water circuits, so as to realize the upper part of the fresh air humidifier respectively. Heat exchange with the waste heat heat exchanger corresponding to the lower part;

[0069] In the dehumidification mode, the waste heat exchanger cor...

Abstract

The invention belongs to the technical field of distributed energy and air conditioning, and discloses a PEMFC combined supply fresh air purification, dehumidification and humidification device and a control method thereof.In the PEMFC combined supply fresh air purification, dehumidification and humidification device, the fresh air purification and humidification device is provided with a box body, a shaft is installed in the box body through a shaft hole, the shaft penetrates through a heat insulation and preservation material, and the heat insulation and preservation material is arranged in the box body; one end is connected with the motor; fins are arranged on the upper side of the heat insulation material and coated with an MOFs adsorption material; the upper side of the box body is provided with an upper half air inlet and outlet, and the lower side of the box body is provided with a lower half air inlet and And the fresh air purifying and humidifying device is connected with the first heat exchanger. The PEMFC provides electric quantity needed by the device and heat needed by solid adsorbent regeneration, and compared with a traditional fresh air dehumidification device, the situation that cold and heat are counteracted can be effectively avoided, the unit cost is effectively reduced, and the purposes of energy conservation and environment protection are achieved; the application requirements of the solid adsorbent can be met.

Description

technical field [0001] The invention belongs to the technical field of distributed energy and air conditioning, and in particular relates to a fresh air purification, dehumidification and humidification device with PEMFC combined supply and a control method thereof. Background technique [0002] At present, energy is the lifeblood of national economic development and an important pillar of national development. With the global attention to the development of new energy, hydrogen energy technology has become the competitive frontier of a new round of technological revolution and industrial transformation. At present, the production, storage, transportation and use of hydrogen are very mature, safe and reliable, and the proton exchange membrane fuel cell (PEMFC) using hydrogen as raw material has been developed rapidly. PEMFC has the advantages of high energy conversion efficiency, no emission pollution, power generation efficiency is less affected by load, and a wide range of...
