Abstract

The invention discloses a spraying type condenser, an evaporative cooling refrigerator, an evaporative cooling air conditioner and an application method thereof. The spraying type condenser comprises a gas-liquid heat exchanger with a transverse connecting channel, the gas-liquid heat exchanger is provided with a forward spraying assembly, a reverse spraying assembly is arranged on the lower side of the transverse connecting channel, a water spraying port of the reverse spraying assembly faces the bottom of the transverse connecting channel, and the spraying type condenser is provided with a water supplying assembly connected with the forward spraying assembly and the reverse spraying assembly. The evaporative cooling refrigerator comprises an evaporator assembly and the spraying type condenser. The evaporative cooling air conditioner is an air conditioner body comprising the spraying type condenser and the evaporator assembly. The application method of the evaporative cooling air conditioner comprises the step of controlling the evaporative cooling air conditioner to conduct refrigerating operation which is one of the multiple modes. According to the spraying type condenser, the evaporative cooling refrigerator, the evaporative cooling air conditioner and the application method thereof, heat exchange property degradation caused by condenser scaling can be prevented; and for an air conditioner system running all year round, energy consumption of the air conditioner can be significantly reduced, all-year-round safe running of the system is guaranteed, and limitation of evaporative cooling technology application is broken.

Description

technical field [0001] The invention relates to air treatment equipment, in particular to a spray condenser, an evaporative cooling refrigerator, an evaporative cooling air conditioner and an application method thereof. Background technique [0002] According to the statistics of relevant departments, the electricity consumption of air-conditioning systems has reached more than 15% of the total electricity consumption of the whole society. Certain industries and places that generate large amounts of heat, require high temperature and humidity, and require refrigeration all year round account for as much as 40% of their energy consumption. %above. Therefore, the energy saving of air conditioning system is of great significance. [0003] The energy consumption of the air conditioning system is composed of refrigeration energy consumption, refrigerant transmission energy consumption and fan energy consumption, and refrigeration energy consumption accounts for the highest propo...

AI Technical Summary

Problems solved by technology

Air cooling system: the system is simple, but the cooling energy consumption is high, and the condenser is easy to corrode in the polluted environment; water cooling system: the compressor energy consumption is low, but the transportation energy consumption and water consumption are high, and it occupies a large area, the investment of the water system is large, and it is operated in winter Need to add antifreeze, its leakage is large and slightly toxic

Theoretically, the evaporative cooling method has the highest efficiency, and its modularity can have the advantages of both air-cooled and water-cooled systems, but the following two reasons limit its application

[0004] 1. The condenser is easy to foul and difficult to remove

[0005] At present, the commonly used tubular condenser, spray water from top to bottom to form a large area of ​​back water surface, splashing water on the back water surface is easy to produce dry spots, forming serious scaling, reducing heat transfer efficiency and not easy to remove

[0006] 2. The use is limited by climatic conditions

[0007] When the outdoor temperature drops to 0°C, the water mist in the exhaust air will easily cause the surface of the filter at the air outlet and air inlet to freeze, block the flow channel and make it impossible to operate normally, which means that in the north of the Yangtze River Basin and most of the Yangtze River Basin , the use of evaporative cooling technology in the above occasions is limited
