Description
Technical Field
The invention belongs to the field of energy conservation of refrigeration and air-conditioning equipment, and particularly relates to a novel split air-conditioning device.
Background
The split air conditioner consists of evaporator, compressor, condenser, throttle valve, etc. and is connected successively to form a closed system. During refrigeration, the compressor sucks low-temperature low-pressure cold gas in the evaporator into the cylinder, work is performed by the compressor, the low-temperature low-pressure cold gas becomes high-temperature high-pressure gas, the high-temperature high-pressure cold gas exchanges heat with air in the condenser, and the cold gas is condensed into high-pressure liquid. The high-pressure liquid is depressurized by the throttle valve and then enters the evaporator of the indoor unit, and the refrigerant of the low-pressure liquid in the evaporator immediately vaporizes and absorbs heat of surrounding air, so that the surrounding air is cooled, the indoor fan continuously sucks indoor air, and the indoor air is cooled by the evaporator and then enters the room, so that the indoor temperature is reduced. The vaporized low-pressure low-temperature refrigerant is sucked and compressed again to realize continuous refrigeration. When heating, the four-way valve is changed to the back, the indoor unit becomes the condenser, the high-temperature high-pressure cold gas discharged by the compressor is changed to the condenser, and in the condenser, the high-temperature cold gas exchanges heat with the surrounding air and gives off heat to condense into liquid-state cold gas, and the purpose of heating is realized through the action of the fan. The high-pressure refrigerant liquid leaves the condenser, is depressurized by the throttle valve, enters the outdoor evaporator, and is continuously vaporized in the outdoor evaporator to absorb heat of surrounding air. And then is sucked and compressed by a compressor, so that continuous heating is realized.
The existing split type air conditioner mainly adopts a vapor compression type refrigerating system, the supercooling degree of the refrigerant is often insufficient, the refrigerating capacity is insufficient for the refrigerating system, the refrigerant is unevenly distributed, the efficiency of an evaporator is low, and the energy consumption is high. Aiming at the problems, the Chinese patent CN108571787A adopts a method capable of realizing zero discharge of condensed water and obviously reducing the condensation temperature of the outdoor unit and improving the operation energy efficiency ratio in the refrigeration process, wherein one end of a condensation water pipe is connected with the indoor unit, and the other end of the condensation water pipe is connected with the outdoor unit, so that the condensed water generated by the indoor unit is led into the outdoor unit. The outdoor unit is internally provided with a spray pipe, a condensing fin and a fan, wherein the spray pipe is arranged above the condensing fin and is connected with a condensing water pipe for spraying condensed water in the condensing water pipe on the condensing fin. The condensed water sprayed on the surface of the condensing fins is rapidly evaporated under the action of the fan, and the heat of the condensing fins is taken away in the evaporation process, so that the zero discharge treatment of the condensed water and the cooling of the condensing fins are simultaneously considered. However, the method does not give consideration to the problem of high energy consumption in transition seasons. The chinese patent CN2126558Y uses waste condensed water to supercool the condenser, so as to achieve the purposes of improving refrigerating capacity and reducing power consumption. However, the method occupies a part of heat exchange area of the original condenser, so that the condensing pressure is increased, and the power consumption of the compressor is increased.
In order to overcome the defects, the invention discloses a novel split air conditioner, which uses the generated cold energy to prepare cold water through a radiation refrigeration film to realize cold accumulation and air conditioner refrigeration functions; the solar radiation energy is converted into heat energy through the solar heat absorption film and is used for preparing hot water, so that the heat storage and air conditioner heating functions are realized. The indoor temperature and humidity adjusting device is combined with a traditional split air conditioner, so that the indoor temperature and humidity adjusting function of the split air conditioner can be realized, a natural cold source and a heat source can be fully utilized, the energy saving effect is achieved, and the system is simple in structure.
