Abstract
A low temperature energy carrying apparatus and method adapted for central cooling which comprises a hydrate circulating system for a liquid hydrate agent and hydrate crystals incorporated with a conventionally designed water circulating system. In the hydrate circulating system, the hydrate crystals are feed to the users side together with cooled water and decomposed therein into hydrate agent and cooled water absorbing the latent heat of decomposition. Therefore, the temperature of the cooled water during transport thereof to the users side is stabilized and in addition to the sensible heat of the cooled water the latent heat of the hydrate crystals can be utilized in the users side, thereby improving cooling effect in the users side. Also, the hydrate circulating system is adapted to use a hydrate agent in the liquid phase area which allows the operation of the system to be stabilized.
