Abstract

1. Способ охлаждения подземных сооружений в массиве многолетнемерзлых горных пород, включающий подземное сооружение, минимум одну горизонтальную трубу в грунте и минимум одну вертикально ориентированную трубу, выступающую над поверхностью земли, причем внутренние объемы вертикальной и горизонтальной труб соединены, отличающийся тем, что минимум одна горизонтальная охлаждающая труба уложена в основании слоя сезонного оттаивания.2. Способ по п.1, отличающийся тем, что подземное сооружение располагается на глубине, определяемой формулой:, где:h- глубина сезонного оттаивания грунтов, в подошве которой располагают трубы охлаждающего устройства;τ - продолжительность работы охлаждающего устройства в холодное время года;λ и C - средние значения коэффициента теплопроводности и объемной теплоемкости грунтов в кровле подземного сооружения;T - период колебаний наружного воздуха.3. Устройство для летнего охлаждения подземных сооружений, включающее подземное сооружение, минимум одну горизонтальную трубу в грунте и минимум одну вертикально ориентированную трубу, выступающую над поверхностью земли, причем внутренние объемы вертикально ориентированной и горизонтальной труб соединены, отличающееся тем, что количество вертикально ориентированных труб минимум две, причем обе трубы верхним концом выполнены сообщающимися с атмосферой, нижние концы вертикально ориентированных труб соединены каждая со своим коллектором, между которыми расположены горизонтальные параллельные трубы.4.
