Due to the KTV industry began to rise, because it belongs to high places, so most of the KTV will use central air conditioning, then KTV central air conditioning and other places of the central air conditioning is what different?, which mainly and the characteristics of the KTV relationship, through many years of construction experience we return to accept the following points: 1, KTV is entertainment, personnel, mobility, so the cooling load selected standards should be higher than the common places, according to experience at the end of the selection criteria for the 300-400w/m2 host cold load of selection criteria for 150 W / m2. 2, KTV private rooms of varying sizes, space is limited and the suspended ceiling is complex, in order to integrate perfectly with the ceiling, the general use of the top send airflow organization form, not only can raise the ceiling height is in favor of condensed water discharge, inlets in the background on the other side of the wall, air inlet is arranged on the side surface suspended at the top is not easy to be found, can improve the grade and beautiful degrees of room. 3, KTV is a confined space, poor air circulation, in order to improve air quality recommended design, exhaust system, fresh air using fresh air unit input to the indoor fresh air, exhaust the axial flow fan to the indoor dirty air to indoor, to the beautiful ceiling is generally not a single set new air, fresh air inlet is directly connected to the at the air outlet, exhaust separate exhaust outlet, general on the sofa is central, sofa is the central projection can are located on either side. 4, KTV room opened in accordance with the decision of the traffic, so the module air-cooled chiller is more practical, because the module each machine unit 4 sets of scroll compressor, respectively started, compressor according to the room open free start, every unit are independent of the system, and another for repair does not affect the work of other units, throughout the year can be used
Therefore, KTV design of air conditioning system, choose cold and heat source and arrangement of send, air port, must give full consideration to the KTV own characteristics, reasonable design.
2.Project Overview
Due to the KTV industry began to rise, because it belongs to high places, so KTV majority will mining this project is located in Ji ning City, Shan dong Province, for a total of three KTV building, which belongs to the buildings; construction area of 6000 square meters pided three fire partition, each partition has an area of not more than 1000 square meters, have a direct external exit, including building air conditioning design, ventilation design, ventilation design content
