Помогите, пожалуйста, перевести это предложение:
Their temperature hardly changes throught the cycle since it is their latent heat capacity which brings about the change in air temperature.

Вот контекст:
The system invented by david Etheridge and David Rae draws daytime warm external air by fan over an array of filled heat pipes. The pipes conduct heat to storage modules containing a solid phase change material. During the night the opposite occurs.
The whole operation works on the principle that latent heat is stored in the phase change materials. Their temperature hardly changes throught the cycle since it is their latent heat capacity which brings about the change in air temperature.

Заранее благодарна

Их температура почти не меняется в ходе цикла, поскольку именно их скрытая теплоемкость вызывает изменения температуры воздуха.
