The utility model provides an evaporative cooler. As shown in fig. 1-4, the evaporative cooler comprises at least one row of evaporative cooling tubes, and primary air transversely passes through gaps among the evaporative cooling tubes and is in contact heat exchange with the evaporative cooling tubes;
the evaporation cooling pipe is provided with an air inlet and a spraying port 12;
the air inlet of the evaporative cooling pipe is positioned at the bottom of the pipe body and is communicated with the main air inlet 11 of the evaporative cooler, and secondary air enters from the air inlet and flows upwards along the evaporative cooling pipe;
the spray opening 12 is positioned at the top of the evaporative cooling pipe, and condensed water enters from the spray opening 12 and flows downwards along the evaporative cooling pipe;
the spraying assembly is used for spraying from the spraying port into the evaporative cooling pipe;
the device also comprises a fan 2 for guiding secondary air to enter the evaporative cooling pipe, and performing damp-heat exchange with spray water so as to exchange heat with the evaporative cooling pipe;
the refrigeration device also comprises a refrigeration coil 3, wherein the refrigeration coil 3 is arranged on the evaporation cooling pipe and exchanges heat with the evaporation cooling pipe.
The primary air is the circulating air which needs to be cooled at the indoor side. The secondary air is outside air and is used for carrying out damp-heat exchange with spray water to provide cold energy, and is a natural cold source, and the secondary air enters from the air inlet and flows upwards along the inside of the evaporative cooling pipe. The refrigerating coil 3 can be injected with secondary refrigerant or refrigerant, and is an artificial cold source, not only can supplement cold for primary air, but also can dehumidify secondary air and reduce the temperature of dry balls of the secondary air, further enlarges the temperature reduction capability during the wet heat exchange, and furthest exerts the effect of evaporative cooling, so that the evaporative cooler is more energy-saving overall. Compared with a split structure of an evaporative cooler, a dehumidifier and a surface cooler, the structure has the advantages that the occupied space is smaller, and the cost and the energy consumption are lower due to the fact that the dehumidifier and the surface cooler are reduced.
This embodiment has set up one row of evaporative cooling pipe, as required, also can set up two rows or even multirow evaporative cooling pipe to improve the refrigerating output.
Conventional evaporative coolers take the form of evaporative cooling tubes plus fins. The evaporative cooling pipe is usually a round pipe and is used for heat exchange between spray water and secondary air; the fins are used for enhancing the heat exchange capacity between the evaporative cooling tubes and the outside and primary air. However, this form has a relatively large pressure loss to the primary air. And the fins need to be in heat transfer with the evaporative cooling tubes, so that the efficiency is low. The evaporative cooling tubes in this embodiment are formed of hollow shuttle fins 1. Namely, the fins are evaporative cooling tubes, and are equivalent to two fins which surround front and back to form a hollow evaporative cooling tube. After the spindle shape is changed, the spindle shape is arranged along the flowing direction of primary air, and compared with an evaporative cooling pipe with a round pipe, the wind resistance is smaller. The fin can be directly with the endothermic secondary air heat exchange of inside evaporation, directly contact the heat transfer with outside primary air simultaneously, and heat exchange efficiency is higher.
In this embodiment, the refrigeration coil 3 includes a plurality of rows of tubes arranged at intervals, and the evaporation cooling tube is connected by the plurality of rows of tubes from bottom to top in a transverse penetrating manner. The row tubes have both portions passing through the inside of the shuttle fins 1 and portions exposed to be in contact with the primary air. The penetrating position is sealed, and good heat conduction connection is formed between the penetrating position and the shuttle-shaped fin 1. When primary air passes through, heat exchange can be carried out simultaneously with the shuttle-shaped fins 1 and the refrigerating coil 3, and the refrigerating coil 3 can play an effective cold supplementing role on the primary air. In the process that the secondary air passes through the fusiform fins 1 from bottom to top, the cooling coil 3 can cool and dehumidify the secondary air.
In this embodiment, the material of the shuttle-shaped fin 1 is a hydrophilic aluminum foil. Hydrophilic aluminium foil has carried out hydrophilic processing to the aluminium foil material, and its surperficial tectorial membrane one deck hydrophilic layer, and the shower water can scatter rapidly at hydrophilic layer, increase and secondary air's heat exchange area.
In this embodiment, the leeward side of the shuttle-shaped fin 1 is bent to form the water blocking edge 13. When primary air exchanges heat with the fins, water drops are easily condensed, and the water blocking edge 13 can prevent the water drops from flying apart.
The spray water in this example uses the collected condensed water and spray water. The spray assembly comprises a water pan 4, a water pump, a spray pipe and a spray header 5.
Wherein the water collector 4 is located the evaporative cooler bottom, and the water droplet that fusiformis fin 1 and primary air, secondary air heat transfer condensation formed can flow into in the water collector 4 along fusiformis fin 1 downwards, and the shower water that does not have after spraying evaporated also can flow back to water collector 4 simultaneously.
The spray head is positioned above the spray opening 12, and the water pump is used for pumping the condensed water in the water pan 4 to the spray head through the spray pipe.
In this embodiment, the flowing medium in the refrigeration coil 3 is water, and includes medium temperature water at a temperature above 10 ℃ and chilled water at a temperature below 10 ℃. More staged and other temperatures of coolant may also be used. The water with different temperatures can be used for supplementing cold in a mode of lower energy consumption according to needs.
Arranging a temperature sensing bulb at the primary air outlet side of the evaporative cooler, and detecting whether the air supply temperature reaches a set value or not through the temperature sensing bulb;
when the air supply temperature does not reach a set value after the evaporative cooler operates for a period of time, the refrigerating capacity is increased by increasing the spraying water amount;
when the air supply temperature can not be reduced after the spraying water amount is increased, the refrigerating coil 3 flows into a heat exchange medium for heat exchange.
In the embodiment, when the air supply temperature does not reach the set value after the spraying water amount is increased, medium-temperature water is injected into the refrigerating coil 3;
and when the air supply temperature does not reach the set value after the flow of the intermediate temperature water is increased, switching the intermediate temperature water into chilled water.
As shown in fig. 5, the evaporative cooler automatically enters an evaporative cooling mode upon activation. This mode preferentially uses a natural heat sink to ensure low power consumption. Under this mode, the butterfly valve of intaking of refrigeration coil 3 closes, and spray assembly starts. The spray assembly pressurizes the spray water from the water receiving disc 4 to the spray head through the water pump to spray out. The sprayed shower water enters the shuttle-shaped fins 1 through the opening of the upper guard plate 6 of the outer frame of the evaporative cooler. Simultaneously, fan 2 starts, and inside outdoor new trend was regarded as the secondary air, got into evaporative cooler by the secondary air intake, the secondary air intake was equipped with the filter to filter the secondary air. The filtered secondary air enters from the lower-section pipe orifice of the evaporative cooling pipe in the evaporative cooler, forms convection with spray water in the pipe, and simultaneously performs damp-heat exchange, so that the heat of the primary air is transferred from the outer wall of the shuttle-shaped fin 1 → the inner wall of the shuttle-shaped fin 1 → the spray water film → the secondary air, and finally is taken away from the interior of the evaporative cooler by the secondary air and is discharged to the outside. The secondary air at this time is an isenthalpic humidification process, and theoretically can reach the wet bulb temperature at the lowest.
The temperature sensing bag is used for detecting whether the primary air supply temperature reaches a set value. If the temperature of the water is not reduced after the spraying water amount is increased, a combined refrigeration mode is entered.
And (2) entering a combined refrigeration mode, opening a butterfly valve of a refrigeration coil pipe 3 in the evaporative cooler to set the opening degree, and allowing medium-temperature water to enter the refrigeration coil pipe 3:
in the wet channel in the fusiform fin 1, the secondary air is dehumidified and precooled, the secondary air and other humidity are condensed after being cooled to the dew point temperature, the wet bulb temperature is reduced, the wet bulb efficiency of the evaporative cooler is increased, and the refrigerating capacity is improved.
In the dry channel outside the shuttle-shaped fin 1, the primary air is cooled in a secondary way.
If the temperature of the refrigerant is not yet at the set value, the opening degree of a butterfly valve of a water inlet pipe of the refrigeration coil 3 is increased, the flow of the medium temperature water is increased, and the refrigeration capacity is improved until the set air supply temperature is reached. If the opening of the butterfly valve is adjusted to the maximum and the set air supply temperature is not reached, the opening of the butterfly valve is switched to chilled water to repeat the opening adjusting process of the water valve. If the opening of the chilled water butterfly valve is adjusted to the maximum value and the set air supply temperature is not reached, an alarm is started to remind a worker to overhaul.
The medium-temperature water is mainly obtained through the outdoor dry cooler, extra electric energy is not consumed, the outdoor temperature is lower than the indoor temperature in winter aiming at places such as a data center machine room and the like needing year-round refrigeration, chilled water can be easily obtained, and a host does not need to be started.
The utility model also provides an air conditioner, which comprises the evaporative cooler described in any one of the embodiments.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
