Embodiment
The present invention is elaborated below in conjunction with the accompanying drawings
As shown in Figure 1, the novel anhydrous geothermal heat pump air-conditioning system, the return air of air-conditioned room 13 largely pass through
Return air inlet 9 is fully exchanged heat with soil 14 into heat exchanger tube 11, the air after heat exchange enter air-conditioning box 15 and
The fresh air entered simultaneously is mixed, then is filtered by roughing efficiency air filter 4, and the air after filtering enters by humidifier 3
Row humidification process, filtered again through medium effeciency filter 1 afterwards, room is then sent into by air outlet 10.Wherein, wind
Machine 2 provides power for whole system；Air temperature regulator 6 automatically controls return air by measuring mixed air themperature
The unlatching size of regulating valve 8 and fresh air regulating valve 7, and then return air amount and resh air requirement are controlled, it is met mixed air
Temperature (pays attention to：Resh air requirement must is fulfilled for the minimum air quantity of room requirement)；After air humidity adjustor 5 is by measuring mixing
Air humidity come automatically control the control valve of humidifier so that control air humidity it is met design requirement.
As shown in Figure 2, the heat exchanger tube of the novel anhydrous geothermal heat pump air-conditioning system, with soil contact portion outside
Tube wall surface carries small fin 12, and finned length is 3~5cm, and spacing of fin is 6~10cm, in order to increase heat exchange
The coefficient of heat transfer of pipe outer tube wall and soil, and then strengthen the heat exchange of inner air tube and soil.In addition, not with soil contact portion
The surface of heat exchanger tube must increase Insulation, in order to avoid inner air tube from carrying out heat exchange with extraneous and then influence empty
Adjust effect.
The novel anhydrous earth-source hot-pump system, into heat exchanger tube return air blast velocity control in 0.5~2m/s, in order to
Return air is set fully to be exchanged heat with soil.In underground, the 10~30m soil moisture maintains 17~19 DEG C of (different regions throughout the year
Geological conditions it is different can difference), summer room return air after the sufficient heat exchange of soil progress by humiture with handling
Make a gift to someone room, wherein 26 DEG C or so of return air parameter, relative humidity 55% or so, air dew point temperature is 16.1 DEG C under this state
