Rational Matching And Calculation On The Air-conditioning System Of YBL6113H Bus

If the bus air-conditioning system design is reasonable, not only can improve passenger's riding comfortableness, but also can increase the product's competitive ability greatly in market. As a result of the product renewal, in the YaxingBenz limited company, some MRT-â… import air conditioning should install originally in BENZ O331 bus, now urgently needs in YBL6113H bus to use. In order to can sell these roof-top air-conditioners smoothly, the value is several hundred thousand Yuan , saves the cost for the company, also may avoid to conflict with consumer effectively because of refrigeration quantity insufficiency questions and so on, the sincerity is responsible for the user, carries on the reasonable design calculation to this bus air-conditioning system and analyzes has the necessity very much. In the paper, how to match the air-conditioning system reasonably is the main research content, to determine MRT-â… air conditioning installs in YBL6113H bus whether appropriate.(1) First, the entire air conditioning room heat transfer process has carried on detailed analysis in the paper, know it is a non-stable state heat transfer process, and determined to use the unstable overtone respond method to calculate the air conditioning cold load to be reasonable, then utilized the overtone respond method, the summer cold load has counted to YBL6113H air conditioning bus, and calculated the amount of sending wind. Through computation can know that installs cold king MRT-â… air conditioning mounted on the roof in YBL6113H bus, theoretically is definitely may satisfy the bus the refrigeration and the amount of sending wind request.(2) From the air conditioning refrigeration principle and the...
