An ionic air cooling device comprising a salinity differential heat engine using a heat pump as the primary heat source and the mechanism by which the temperature differential is achieved. A closed loop thermodynamic cycle which produces a high thermodynamic efficiency in heat to energy conversion with a low temperature differential between the high and low sides, in addition to a net ambient temperature cooling effect by directly or indirectly converting ambient temperature/environmental low grade heat to electricity or potential kinetic energy or mechanical work. An ionic air cooling device which uses a salinity differential heat engine in which the heat energy can be converted to kinetic or electrical energy by means of pressure retarded osmosis, pressurized gas through volume confinement, or reversed electro dialysis.

An air handling unit, particularly for data center cooling, operates to cool a flow of return air from a conditioned space using a flow of ambient air. The return air is recirculated to the conditioned space as supply air. The flow of ambient air can be adiabatically cooled to a lower temperature to provide additional cooling. A flow of makeup air can be joined with the cooled return air to form the supply air, and can be sourced from the ambient environment directly or from the heated flow of ambient air.

The present invention relates to a system and method of cooling by latent energy transfer and, in particular, to cool a fluid by discharging unwanted low temperature thermal energy to a surrounding ambient environment utilising a fluid evaporation process involving permitted or forced ventilation of air across a surface area of a heat transfer fluid. The invention further relates to an air treatment system utilising the cooled heat transfer fluid for cooling air and for supplying ventilation air to the evaporation process. A body of liquid is cooled close to the prevailing wet bulb temperature, discharging unwanted thermal energy to the surroundings, rendering the liquid suitable as a cooling medium for removing unwanted thermal energy from a location or in a process.

An integrated type air conditioning device includes a first refrigeration cycle that is an evaporative cooling type, a second refrigeration cycle that is a vapor-compression type, a blower device, and a housing accommodating the first and second cycles. The first refrigeration cycle includes an evaporation heat exchanger, a condensation heat exchanger, and a first refrigerant pipe. The second refrigeration cycle includes a compressor, a condenser, a decompression device, an evaporator, and a second refrigerant pipe. The housing is partitioned into an interior air passage and an exterior air passage.

The blower device is disposed in the interior air passage and is driven to generate the interior airflow in the interior air passage.

The present invention relates to a wet evaporation-based cold concentration system, which is mainly applied to the technical field of air conditioners, and particularly applied to the technical field of heat-source tower heat-pump air conditioners. By utilizing a wet evaporation theory, a low-temperature low-concentration anti-freezing solution is enabled to contact low-temperature air in a wet evaporator to perform the heat and mass transfer, and water in the anti-freezing solution is vaporized at a low temperature into the air, thereby obtaining the high-concentration anti-freezing solution. By reasonably utilizing the concentration pool and the storage pool, the low-concentration anti-freezing solution is separated from the high-concentration anti-freezing solution, thereby achieving a purpose of simultaneously concentrating and storing the anti-freezing solution

Embodiments of the invention utilize the geothermal energy exchanger and battery (GEEB) to recover and store thermal energy from the dwelling, from the ground, and from the Earth's atmosphere, reuse the thermal energy in another season of the year, and consume electrical energy to heat and cool the structure at electrical Off Peak time periods.
