Mine air conditioner

Abstract

The invention relates to an air conditioner, in particular to a mine air conditioner. A compressor (2), a condenser (3), a drying filter (4), a throttling device (5), an evaporator (6), an air feeder (7) and a control box (8) are all integrally arranged in a box body (1). The communication position of a water inlet pipe (11) and a water guide pipe (12) and the communication position of a water outlet pipe (15) and a water collecting pipe (14) are respectively arranged at different ends of the whole condenser (3). The mine air conditioner has the advantages of being low in cost, convenient to install and maintain, small in occupied space, capable of freely controlling a refrigeration position, and good in refrigeration effect.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a mine air conditioner. Background technique [0002] Mine air conditioner is a device for ventilating cold air to cool down the miners in the high temperature environment in summer. The mine air conditioners in the prior art generally use ground centralized cooling, so it is necessary to install a large-power air conditioner on the ground. And it may need multiple compressors to work together, so as to better cool down the mining personnel in the mine. It is not easy to control the position of ventilation and cooling in this way, the cooling effect is not good, and the cost is high, and because there are many equipments, the distribution It is not very concentrated, so it may take up a lot of space, and it is not easy to install and maintain.

[0002] Mine air conditioner is a device for ventilating cold air to cool down the miners in the high temperature environment in summer. The mine air conditioners in the prior art generally use ground centralized cooling, so it is necessary to install a large-power air conditioner on the ground. And it may need multiple compressors to work together, so as to better cool down the mining personnel in the mine. It is not easy to control the position of ventilation and cooling in this way, the cooling effect is not good, and the cost is high, and because there are many equipments, the distribution It is not very concentrated, so it may take up a lot of space, and it is not easy to install and maintain

[0003] The condenser on the mine air conditioner of the prior art includes a water inlet pipe 18, a water guide pipe 19, a heat exchange pipe 20, a water collection pipe 21 and a water outlet pipe 22. Because there are multiple sets of heat exchange pipes 20, the whole condenser can form a plurality of heat dissipation circulation channels, such as Figure 4 As shown in the schematic diagram of , the multiple sets of heat exchange tubes 20 are respectively connected to the water pipe 19 and the water collection tube 21, and the multiple sets of heat exchange tubes 20 are all of the structure of inner and outer tubes, that is, water flows through the outer tube, and water flows through the inner tube. refrigerant, so the outer tube of the heat exchange tube 20 is connected to the water pipe 19 and the water collection pipe 21, and because the water inlet pipe 18 is connected to one end of the water pipe 19, and the water outlet pipe 22 is connected to one end of the water collection pipe 21, but because the water inlet pipe 18 is connected to the water pipe 19 and the water outlet pipe 22 is connected to the water collecting pipe 21 at the same end of the entire condenser (the same end refers to the connection between the water inlet pipe 18 and the water pipe 19, which is located at the left end of the water pipe 19 and exits at the same time. The connection between the water pipe 22 and the water collection pipe 21 is located at the left end of the water collection pipe 21; or the connection between the water inlet pipe 18 and the water guide pipe 19 is located at the right end of the water guide pipe 19 while the connection between the water outlet pipe 22 and the water collection pipe 21 is located at the right end of the water collection pipe 21), which leads to The length of each complete heat dissipation circulation channel is different, so that the resistance in each heat dissipation circulation channel is different, that is, the water flow in each heat dissipation circulation channel is different, which makes the heat transfer of each heat dissipation circulation channel uneven, which leads to The heat transfer effect of the entire condenser is not good, which eventually leads to poor cooling effect of the entire mine air conditioner
