Abstract：The temperature effect generated by a single freezer in a stable temperature field is equivalent to the temperature effect generated by a point cold source in an infinite medium plane.A general solution for solving the temperature field of a frozen wall in a stable state of complex piping can be obtained by using the basic solution for the temperature effect generated by a point cold source in an infinite medium can be obtained through linear superposition,the basic formula for the tempera-ture field of a frozen wall in a straight wall is given.The accuracy of the calculation results based on the above calculation method was verified by using temperature measurement data from a frozen wall.On this basis,the average temperature of full thickness and load bearing thickness of straight frozen wall with one row,two rows and three rows of pipes were studied.And the explicit calculation formu-las was provided.The calculation examples showed that the obtained formulas were simple and feasible for design of freezing wall.
