摘要:
A heat exchanger with improved heat exchange capability mainly includes a primary heat exchanger, a water vaporization device and a secondary heat exchanger. The secondary heat exchanger may be coupled with the water vaporization device to generate liquid and vapor phase transformation to increase heat exchange capability of the heat exchanger and save energy and reduce thermal pollution.

The effectiveness of an evaporative cooler is increased in a construction having a housing (10) provided with an air entrance (18) and an air exit (20) together with a substantially closed air flow path (32) extending between the entrance (18) and the exit (20). A body (34) of evaporative cooling media is within the housing (10) and extends across the air path (32). The body has an upper end (39) and upstream and downstream sides (46), (38). A water distribution plate (54) is located above the body (34) and has an elongated edge (60) which contacts the body (34) along the entire length of the edge (60) at a location at or closely adjacent the upstream side (46). A spring (78) biases the edge (60) against the body (34) and a water distribution header (64) overlies the water distribution plate (54) and directs water onto the plate (54) as a plurality of merging streams.
摘要:
A heat exchanger for a medium condenser having a plurality of vertical cooling fins having extra length extended both upwardly and downwardly from an ordinary portion of medium coil path for greatly increasing the cooling efficiency thereof, and a drip-drop type water feeding box for feeding water drops to a top of cooling fins densely but intermittently to let each of water drop remain in the space between opposite surfaces of adjacent cooling fins a short period of time and start to slide down the surface of a cooling fin as a next drop of water is delivered to provide enough time for evaporation so as to absorb a large quantity of latent heat and increase cooling efficiency.

An alternative powered evaporative cooler has a squirrel cage fan. A low voltage DC motor is provided to power the squirrel cage fan. A pulley system is coupled to the squirrel cage fan and the low voltage DC motor for transferring energy from the low voltage DC motor to rotate the squirrel cage fan. A low voltage DC power source is provided to power the low voltage DC motor.
摘要:
A method for evaporating liquid, in which a drum 1 in which there are passages 8 which extend across the thickness of the drum wall 3 is rotated in a trough 5 containing evaporation liquid 6, while a gas is fed from the drum 1 to the passages 8 is provided. As a result of the gas being passed through, the liquid which has been absorbed by the drum 1 evaporates, with the result that heat is extracted from the system of drum 1 and gas passed through. Depending on conditions, the method can be used to cool, for example flows of processed water or to cool air or to desalinate water. A device for carrying out the method and a drum which can be used in the device are also provided.
摘要:
An evaporative cooling apparatus (20) includes a housing (22) and cooling media (48) contained in the housing (22). The cooling media (48) has an air inlet portion (46) and an air outlet portion (60). The air inlet portion (46) is positioned adjacent an air entry side (42) of the housing (22). A fresh water delivery system (54, 136) delivers fresh water (34) to a face (126) of the air inlet portion (46) of the cooling media (48). A recirculated water delivery system (56) delivers sump water (38) from a sump (40) to the air outlet portion (60). A fan section (26) is proximate an air exit side (44) of the housing (22). The fan section draws outside air (50) through the air entry side (42) of the housing (22) and into the cooling media (48) from the air inlet portion (46) through the air outlet portion (60) to produce cooled air (52).
摘要:
A separated type air conditioner with evaporative condensing apparatus comprises an outdoor unit and at least one indoor unit which the outdoor unit includes an evaporative condensing apparatus, a water chiller type evaporating apparatus and a comparative low pressure compressor for circulating a cooling medium system between the condensing apparatus and the evaporating apparatus within the outdoor unit to avoid long distance medium transmitting for improving the energy saving and environment protecting, and characteristically that the evaporative condensing apparatus comprises an evaporative water intermittent supply system to supply water onto a layer of absorptive material covered on the condensing coils intermittly through an electromagnetic valve automatically controlled by a PC board to assume that the amount of water once supplied to the absorptive material will be approximately fully evaporated within a controlled intermittence to provide a highest effect for absorbing evaporative latent heat form the gas state medium in the condensing coils so as to obtain an extreme low temperature that the medium can be condensed by a low relative critical pressure in using a comparative low power medium compressor for saving a large amount of energy therefore, while each indoor unit is respectively formed of a chilled water/air heat exchanger for cooling the air currents to an ideal condition by the chilled water delivered from the outdoor unit through a water circulating piping system.
摘要:
The efficiency of home external condenser units is improved by cooling ambient air by a water mist, preferably formed about 12 inches away from the condenser unit. Mist-forming nozzles or heads are mounted on the condenser unit housing and coupled to a water supply (spigot) via a solenoid valve coupled to the thermostat control circuit for the condenser unit.
