A kind of warm and humid independent control soil natural source capillary tube air conditioning system
Technical field
The present invention relates to warm and humid independence control air conditioner system, particularly to one warm and humid independent control soil natural source capillary tube air conditioning system.
Background technology
Use at present commonly source source pump do capillary tube air-conditioning frequently with method be, the water temperature needed due to capillary radiation system and fresh air dehumidifying system is different, such as capillary tube in summer needs the high temperature cold water of 18 ~ 21 DEG C of water, the low-temperature cold water of 7 DEG C of new blower fan dehumidifying needs;But traditional earth source heat pump unit can only provide the water temperature of a kind of temperature, and as shown above, the high temperature cold water that capillary tube needs typically increases plate type heat exchanger by system and control system obtains low-temperature cold water and high temperature cold water.Aforementioned way has a problems with:
1, with the low-temperature cold water freeze drying of 7 DEG C, owing to surface cooler temperature is high, after dehumidifying, air absolute moisture content is at 13-15 gram/cube, indoor relative humidity 60-65%, there is the biggest condensation risk, feels clouding, will condense when outdoor environment temperature high humility is big, this is also the common fault that current capillary tube air-conditioning has, and often solves with the freezing cold water using 2-3 DEG C.
2, owing to increasing plate type heat exchanger, capillary tube tube side water pump, energy waste is thus made.
3, owing to increasing plate type heat exchanger, capillary tube tube side water pump and controlling accordingly, room system is more complicated, increases machine room area and system investments.
Domestic also have capillary tube exclusively source source pump to use unique system and design of heat exchanger, is capillary tube and provides high temperature cold water, provides coolant, straight swollen evaporation for fresh air dehumidifying system simultaneously.Although this system improves to some extent, but still it is big to there is initial investment, it is impossible to effectively utilizes soil natural source, and owing to sensible heat processes and latent heat processes and is required for consuming heat pump power consumption in continuous firing, there is operating cost high, the bulky shortcoming of machine room.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes a kind of that can not use heat pump solution sensible heat load in summer, utilizes capillary end to carry out the independent temperature-humidity control soil natural source capillary tube air conditioning system of heat exchange.This air conditioning system adds the quantity of soil Cooling and Heat Source used PE pipe, strengthens the heat exchange of soil Cooling and Heat Source and capillary end, can directly use soil Cooling and Heat Source to produce refrigeration in summer and solve sensible heat load, reduce initial investment and energy consumption.
For realizing above-mentioned technical problem, the solution that the present invention takes is: a kind of warm and humid independent control soil natural source capillary tube air conditioning system, including soil Cooling and Heat Source, source pump, fresh air dehumidification unit and capillary end, described soil Cooling and Heat Source is divided into latent heat load soil Cooling and Heat Source and sensible heat load soil Cooling and Heat Source, described capillary end is sensible heat processing component, including undertaking the end face capillary tube of refrigeration duty and undertaking the ground capillary tube of thermic load;Described latent heat load soil Cooling and Heat Source is connected with source pump by latent heat pump and constitutes circulating path;The outfan of described sensible heat load soil Cooling and Heat Source is divided into branch road a and branch road b by after sensible heat pump, described branch road a is connected with source pump by a heating valve, described branch road b is connected with the input of end face capillary tube by a refrigeration valve, the input of described sensible heat load soil Cooling and Heat Source is divided into branch road c and branch road d, described branch road c is connected with source pump by No. two heating valves, and described branch road d is connected with the outfan of end face capillary tube by No. two refrigeration valve;Described source pump is connected to form circulating path also by for warming-up and ground capillary tube;Described source pump is connected with fresh air dehumidification unit also by pipeline.
Further: described soil Cooling and Heat Source is made up of PE pipe, water collecting and diversifying device and pipeline, and the PE pipe quantity of described sensible heat load soil Cooling and Heat Source is more than the PE pipe quantity of latent heat load soil Cooling and Heat Source, to reduce the temperature difference of capillary end and soil Cooling and Heat Source.
By using preceding solution, the invention has the beneficial effects as follows: the warm and humid independent of design controls soil natural source capillary tube air conditioning system as mentioned above, under summer condition, the cold chilled water of described sensible heat load soil Cooling and Heat Source is brought directly to described end face capillary tube, produces refrigeration;Meanwhile, described source pump utilizes latent heat load soil Cooling and Heat Source to produce cold and provides cold to described fresh air dehumidification unit, to fresh air dehumidification;In the winter time under operating mode, bring described sensible heat load soil Cooling and Heat Source, the heat of latent heat load soil Cooling and Heat Source into described source pump, further heat up and be supplied to ground capillary tube afterwards, heat;Therefore, described soil Cooling and Heat Source is divided into two parts, and a part provides cold for sensible heat load in summer, and another part provides low-temperature receiver for latent heat load in summer and provides heat for sensible heat load in winter;The present invention utilizes the high heat-transfer performance of capillary end simultaneously, the heat exchange of soil Cooling and Heat Source and capillary end is strengthened in summer, cold water from sensible heat load soil Cooling and Heat Source is directly entered described capillary end and carries out radiation refrigeration to process sensible heat load, investment and the energy consumption processing sensible heat load heat pump is decreased than source heat pump air-conditioning system traditionally, both decrease initial outlay, also save operating cost;Under winter condition, sensible heat load is directly undertaken by described source pump, heat in described source pump needs not move through the plate type heat exchanger in conventional rack and is just transmitted directly at the capillary tube of described ground, so, the leaving water temperature of described source pump can reduce, improve system effectiveness, reduce energy consumption.
