Abstract:
Objective A correlation method for evaluating operation quality of air conditioning systems is proposed , based on the outdoor and the indoor temperature history data of the terminal user from internet of things for the central air conditioning system , for lacking efficient way to evaluate . Methods A methematical model is set up based on the variance ratio of the data of the indoor and out temperture obtained from IOT within a given time interval , and theoretically induce the possibility and correctness to employ these index to evaluate the operation quality of the central air conditioning system . Results A typical central air conditioning system of a large sacal hospital is analyzed , the results shows the variance ratio of the indoor and outdoor temperature can reflect the capacity of the central air conditioning system for controlling the indoor temperature . Conclusion The method proposed for evaluating the op-eration quality of the air conditioning system based on IOT system is theotically correct and practically efficient , and can be employed to evaluate the operation quality of the air conditioning system of large scale medical buildings .
