Not only the cooperatio nbetwee nCCP and electric air conditioner, but also the influence of purchase prices of electricity and fuel, and electricity sold to public grid is considered i nthis model. Take na nactual office building i nsouth area as a nexample, it is studied the influences o nthe operatio nof CCP system of factors such as capability of MT group, price of electricity sold to public grid and fuel price under the conditio nthat electricity MT generated is allowed to be sold to utility.
