Technical Field
The disclosure relates to the field of air conditioning ventilation, in particular to a power type filtering device.
Background
The comprehensive hospital is a hospital which has a certain number of sickbeds, is divided into various departments such as internal medicine, surgery, gynecology, pediatrics, ophthalmology, otorhinolaryngology and the like and medical and technical departments such as medicament, inspection, radiation and the like, and has corresponding personnel and equipment. In hospital departments adopting the centralized air-conditioning system, more than 80% of pollution in the centralized air-conditioning system comes from return air, so that the pollution of dust and bacteria in the return air to the air-conditioning system must be considered. The strengthening of the return air dust removal and the sterilization is a necessary measure, the circulation frequency of dust and bacteria in the indoor air can be reduced, and the health and the safety of medical care personnel are protected.
7.1.11 in the comprehensive hospital building design specification GB51039-2014 specifies that a filter device with initial resistance less than 50Pa, once pass rate of microorganisms not more than 10% and once weight pass rate of particulate matters not more than 5% must be arranged at a return air inlet of a centralized air-conditioning system and a fan coil unit. In addition, after the filter equipment is added at the air return inlet of the fan coil, the external static pressure of the fan coil needs to be increased due to the large resistance of the filter equipment. However, the static pressure of the fan coil which is delivered from the factory at present is only 30 or 50Pa, and the resistance of the filtering equipment cannot be overcome. Therefore, in order to meet the special requirements of the comprehensive hospital, the equipment manufacturer needs to redesign the fan coil unit used by the comprehensive hospital to adjust the static pressure at the outlet of the unit. This approach would virtually increase the procurement cost of the dedicated fan coil.
