when the operation in summer, outdoor air temperature is higher than original air temperature in utility tunnel 4, outdoor air gets into air intake pavilion 1 through rain-proof tripe type air intake 2, then rethread pipe gallery air intake 3 gets into utility tunnel 4, the cold volume of soil through 4 envelope of utility tunnel transmission cools off the air that gets into in utility tunnel 4 and cools down, low temperature air after the cooling gets into air exhaust passage 6 and the heat transfer is carried out with the high temperature high pressure refrigerant steam in the air side heat exchanger 7 (as the condenser) under fan 8's suction effect, the temperature risees after the air heat absorption, get into air exhaust pavilion 9 afterwards and discharge through rain-proof tripe type air exit 10, utility tunnel 4 realizes ventilation when the air cold volume is retrieved.
The refrigerant gas is changed into high-temperature high-pressure liquid after releasing heat, is changed into low-temperature low-pressure liquid after being reduced in pressure from the air side heat exchanger 7 through the throttle valve 15, is changed into low-temperature low-pressure steam through heat absorption and evaporation of the user side heat exchanger 14 (serving as an evaporator), and the return water temperature of the air conditioner is reduced. The low-temperature low-pressure steam is sucked into the compressor 12 through the four-way reversing valve 13, is compressed through the compressor 12, is changed into high-temperature high-pressure steam, enters the air side heat exchanger 7 from the four-way reversing valve 13, is subjected to refrigeration cycle again, and is recycled through the air cooling capacity in the pipe gallery 4.
The winter operation, outdoor air temperature is less than original air temperature in the piping lane 4, outdoor air gets into air intake pavilion 1 through rain-proof tripe type air intake 2, then rethread piping lane air intake 3 gets into utility tunnel 4, soil heats the air that gets into in the piping lane 4 through the heat of the 4 envelope of utility tunnel transmission and the heat dissipation capacity of heating power pipeline in the utility tunnel 4 and heaies up, the high temperature air after the intensification gets into air exhaust passage 6 and the heat transfer is carried out to the low temperature low pressure refrigerant liquid in the air side heat exchanger 7 (as the evaporimeter) under fan 8's suction effect, the exothermic temperature of air reduces, then get into exhaust pavilion 9 and discharge through rain-proof tripe type air exit 10, utility tunnel 4 realizes ventilation when the air waste heat recovery.
The refrigerant liquid absorbs heat and then becomes low-temperature and low-pressure gas, the gas is sucked into the compressor 12 from the air side heat exchanger 7 through the four-way steering valve 13, the gas is compressed by the compressor 12 and becomes high-temperature and high-pressure refrigerant vapor, the refrigerant vapor is conveyed to the user side heat exchanger 7 (serving as a condenser) to be subjected to heat release and condensation to become high-temperature and high-pressure liquid, the return water temperature of the indoor air conditioner is raised, and the indoor temperature is raised. High temperature high pressure liquid becomes low temperature low pressure liquid after passing through choke valve 15 step-down, and low temperature low pressure liquid is carried to air side heat exchanger 7, heats the circulation once more, and the air energy of flowing through in the piping lane realizes retrieving.
When energy exchange is needed in summer and winter, the fan 8 continuously operates by frequency conversion and speed regulation, and meanwhile, the normal ventilation times of the comprehensive pipe gallery and the heat exchange requirements of indoor heating or refrigeration are met; when need not the energy exchange in spring and autumn, the temperature is little with outside air temperature difference in the utility tunnel, 8 intermittent operation of fan, and the air volume satisfies the utility tunnel normal ventilation number of times can.
