上文已将最关键的因素——传递函数求出,按理便可计算出热流响应日H_0和H_1,最后将它们进行拉氏逆变换返回到时域中去,于是,计算可告全部结束。但是,由于空调系统的扰量例如室外太阳辐射和气温没有精确的函数表达式和相应的拉氏变换式,却只有可供直接利用的采样值(逐时观测值),因此在实际应用中采用另一条更为方便的途径,那就是:用卷积和的办法计算响 The above has been the most crucial factor - the transfer function to find, according to reasonable calculation of the heat flow response date H_0 and H_1, and finally they are inverse transformation to return to the time domain to go, so the calculation may be all over. However, since the air conditioning system disturbances such as outdoor solar radiation and air temperature do not have accurate functional expressions and corresponding Laplace transforms, there are only sampling values ​​available for direct use (hourly observations) and thus are used in practical applications Another more convenient way is to use the method of convolution and calculate the sound
