Application of temperature and humidity independent control air conditioning system in hospital wards

Taking a hospital building in Beijing as an example, presents the applicability and technical advantage of temperature and humidity independent control air conditioning system. Obtains that the air contamination problem of hospital air conditioning, especially caused by central air conditioning system itself could be effectively solved if moisture load is completely undertook by fresh air and fan coil unit is in the mode of dry operation, and indoor air quality greatly improves. Meanwhile, with high temperature water chiller, COP increases by approximately 30%. Double cooling coil heat recovery fresh air handling unit using high temperature chilled water for fresh air primary surface cooling and cold temperature chilled water for secondary surface cooling can reduce energy consumption by approximately 13%. Pre-cooling and reheating fresh air using two-stage heat recovery coil can further reduce the fresh air handling energy consumption.
