A device is provided for supplying heating and cooling, the device having a heat transfer medium arranged in the interior of a storage tank and having at least one cycle process plant operated using a working substance. The heat transfer medium has a lower temperature in a bottom region of the interior than in a region of the interior arranged thereabove. All the components of the cycle process plant that contain the working substance are arranged in the interior. The components of the cycle process plant arranged inside the storage tank are surrounded by the heat transfer medium. The heat transfer medium has constituents to bind or convert the working substance. The amount of the constituent as a proportion of the heat transfer medium is dimensioned in such a way that the working substance contained in the cycle process plant can be completely bound or converted by the constituent after an escape from the cycle process plant.

Technologies are described herein for cooling systems. In some aspects, a cooling system is configured to enter into a storage configuration or a wintenzation configuration. In the wintenzation configuration, refrigerant used in the cooling system is stored in an adsorbent in an adsorbent chamber.

An energy conversion system includes an energy converter, a cold generator, and a liquid water obtainer. The energy converter is configured to convert energy of a source from one form to another form and generate heat and water vapor. The cold generator is configured to generate cold using the heat generated by the energy converter. The liquid water obtainer is configured to condense the water vapor using the cold to obtain liquid water. Accordingly, the water vapor generated from the energy converter can be cooled efficiently. Therefore, efficiency in obtaining the liquid water can be improved compared with a case where the water vapor is cooled by open air.

A sorption heat pump having an evaporator containing a working fluid to evaporate the fluid to produce a gas, a sorber containing a sorption material to sorb the gas during a sorption phase, a vapor pathway connecting the evaporator and sorber, and a thermal control unit controlling the rate of vapor flow between the evaporator and sorber through the pathway, and being selectively operable to permit, stop and restart the flow of gas through the pathway. The pump may be used with a compartment storing temperature sensitive material. The evaporator may be positioned inside and the sorber outside the compartment, or the sorber may be positioned inside and the evaporator outside the compartment. The pump may be used in an apparatus including both cool and warm compartments, with an insulation layer in each. A method is disclosed for reusing the pump after the sorption material has been sorbed.

Disclosed is an adsorption-based heat pump useful for refrigeration and cooling/heating for applications such as HVACs and chillers. Adsorption is a surface phenomenon where a solid substance (adsorbent) attracts molecules of a gas or solution (refrigerant or adsorbate) on its surface. The latent heat of the adsorbate provides the heating/cooling effect. The novel adsorption heat pump enhances heat and/or mass transfer to and from the adsorbate. One embodiment comprises at least one evaporator, at least one desorber (adsorbent heating apparatus), at least one adsorbent cooling apparatus and at least one condenser. The embodiment employs different techniques to enhance heat and/or mass transfer.
