Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The utility model provides an integral type dual energy self-adaptation air conditioning unit, comprises indoor unit 1, outdoor unit 2 and connecting tube, as shown in figure 1, indoor unit 1 is including the filter 11, surface cooler 12, evaporimeter 13 and the forced draught blower 14 that connect gradually, and filter 11 plays the dust in the filtered air, improves the effect of air cleanliness factor, protection heat exchanger 222. The surface cooler 12 circulates water for heat exchange between cold water and air, and the air is cooled by circulating the cold water inside the surface cooler 12. The evaporator 13 is a part of a refrigeration cycle, and the freon circulates inside, and absorbs heat to cool the air by the evaporation of the freon. The blower 14 is a component that powers the air circulation. As shown in fig. 2, the outdoor unit 2 includes a compressor condensing unit 21 and an air cooling unit 22, the compressor condensing unit 21 and the evaporator 13 form a complete freon refrigeration cycle system, and the air cooling unit 22 and the surface air cooler 12 form a heat exchange cycle system. The compressor condensing unit 21 consists of an intercepting fan 211 and a condenser 212, and the condenser 212 and the evaporator 13 form a complete Freon refrigerating cycle system. A compressor 213 is also arranged in the compressor condensing unit 21. The air cooling unit 22 is composed of an axial flow fan 221, a heat exchanger 222 and a water pump 223, and the axial flow fan 221, the water pump 223 and the surface air cooler 12 form a water and air heat exchange circulation system. The circulating water inside the heat exchanger 222 is a part for heat exchange between water and air, and forms a circulating system with the surface air cooler 12 of the indoor unit 1, and the water pump 223 provides power for water circulation. The axial flow fan 221 provides circulating power for air required by the heat exchanger 222 for heat exchange. Because the moving parts of the air cooling unit 22 are only the water pump 223 and the axial flow fan 221, the energy consumption is very low, and the power of the air cooling unit is only about 20 percent of the total distribution power of the system.

The heat exchanger 222 is a finned heat exchanger.

The filter 11 is a primary filter.

The working principle is as follows:

in summer, when the outdoor temperature is higher or the environment temperature is higher than the room temperature, the unit adopts the working mode that the compressor condensing unit 21 of the outdoor unit 2 and the evaporator 13 of the indoor unit 1 operate, the compressor 213 provides the Freon circulating power, and the heat absorbed by the indoor evaporator 13 is dissipated to the outdoor air through the condenser 212. Therefore, the reciprocating circulation meets the requirement of reducing the temperature of a working place. At this time, the system can control the temperature in the room within the set temperature by starting and stopping the compressor 213 according to the temperature change of the indoor place.

In spring and autumn, when the outdoor environment is lower than the indoor required temperature by more than 3 ℃ (at the moment, the air cooling unit 22 directly dissipates heat to adopt economic benefit), the unit automatically starts the circulation of the air cooling unit 22 of the outdoor unit 2 and the evaporator 13 of the indoor unit 1, and at the moment, the indoor heat can be partially carried to the outdoor without the operation of the compressor 213. In this stage, because the ambient temperature is not very low, the energy consumption of the air conditioner can be reduced to the maximum extent by a method of intermittently starting the refrigerating system of the compressor 213 under the condition of ensuring the temperature requirement of a workplace.

In winter, when the outdoor temperature is reduced to be low enough, the system can completely adopt the circulation of the air cooling unit 22 of the outdoor unit 2 and the surface cooler 12 of the indoor unit 1 to cool the workplace, and the energy consumption of the system is reduced to the minimum. The system can accurately control the temperature of the workplace within a set temperature by starting and stopping the water pump 223 and the axial flow fan 221 of the air cooling unit 22.

The structure is compact, and the compressor refrigeration operation of the compressor condensing unit 21 and the air direct cooling operation of the air cooling unit 22 are organically combined, so that the compressor refrigeration operation or the air direct cooling operation can be automatically selected according to the change of the ambient temperature. On the premise of meeting the temperature requirement of a workplace, the change of the ambient temperature is fully utilized, the operation of the compressor 213 is stopped under the condition that the ambient temperature is lower than the temperature in a room, and the mode of directly cooling air is adopted, so that the annual operation energy consumption of the unit is greatly reduced. The refrigeration mode can be automatically selected according to the change of the environmental temperature; the most energy-saving operation mode can be automatically selected by the unit on the premise of meeting the requirements of customers. Can bring great economic benefits for users.
