Description

A kind of two cold source air conditioning systems based on hot pipe technique
Technical field
The present invention relates to a kind of air-conditioning system, especially relate to a kind of two cold source air conditioning systems based on hot pipe technique.
Background technology
At present, the air-conditioning system that base station and machine room use mainly contains two classes: (1) general Household cabinet air conditioner or professional base station air conditioner; (2) hot pipe technique or air heat exchanger etc. is adopted to make full use of the air-conditioning equipment of Environmental cold source.All belong to single refrigerated air-conditioning system.In the most region of China, about there is the time of more than 70% can directly utilize Environmental cold source to come to room cooling, and do not need to start compressor of air conditioner.The time being only less than 30% needs to start compressor to ensure that room lowers the temperature.Outfit two is so just needed to overlap independent air-conditioning system.This type of way mainly contains following defect: (1) needs buying separately two cover air-conditioning system, and cost is high; (2) two cover air-conditioning systems generally do not belong to same company, cannot effectively mate and coordinate, be difficult to produce a desired effect; (3) room space is occupied many, maintenance task weight.
Patent name is: disclose a kind of conditioner in (patent No. is: ZL200920239977) in a kind of two cold source air conditioning group, which employs three refrigerating circuits and realize two cold source air conditioning system, although also achieve two low-temperature receiver refrigeration, but this system cost is higher, higher to requirement for environmental conditions.
Summary of the invention
Object of the present invention be exactly provide to overcome defect that above-mentioned prior art exists a kind of compact to design, control simple, good energy-conserving effect, maintenance easily based on two cold source air conditioning systems of hot pipe technique.
Object of the present invention can be achieved through the following technical solutions:
A kind of two cold source air conditioning systems based on hot pipe technique, it is characterized in that, comprise refrigeration air-conditioner subsystem, hot pipe system, evaporation fan, condensation fan, cooling blower, described refrigeration air-conditioner subsystem comprises compressor, evaporimeter, condenser and expansion valve, described expansion valve, evaporimeter, compressor, condenser connects successively, described hot pipe system comprises heat pipe indoor heat exchanger, heat pipe chamber external heat exchanger, described heat pipe indoor heat exchanger is connected with heat pipe chamber external heat exchanger, the air outlet of described evaporation fan is just to evaporimeter and heat pipe indoor heat exchanger, the air outlet of described condensation fan is just to condenser, the positive opposite heat tube outdoor heat exchanger of air outlet of described cooling blower.
Described heat pipe indoor heat exchanger is shorter than the distance of evaporimeter and evaporation fan with the distance of evaporation fan.
Described refrigeration air-conditioner subsystem also comprises temperature sensor, control device, and described temperature sensor is connected with control device, and described control device is connected with compressor, evaporation fan, condensation fan, cooling blower respectively.
Compared with prior art, the present invention has the following advantages:
1, compact to design: the independent system of two covers is covered and built up a set of pair of cold source air conditioning system, can work independently, also can compound work, requirements of installation space is few.
2, control simply: operational parameter control only has indoor return air temperature, according to return air temperature, control device controls start and stop and the operating air velocity gear of start/stop of compressor, evaporation fan and condensation fan.
3, good energy-conserving effect: the present invention is variations in temperature environmentally, control device controls to start blower fan and compressor combination, and be down to minimum by compressor and fan operation time, power consumption is down to minimum.
4, maintenance is convenient: the same conventional air-conditioning of moving component quantity, stable, easy to maintenance, without other particular/special requirements.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of two cold source air conditioning systems based on hot pipe technique, comprise refrigeration air-conditioner subsystem, hot pipe system, evaporation fan 3, condensation fan 4, cooling blower 6, described refrigeration air-conditioner subsystem comprises compressor 11, evaporimeter 12, condenser 14 and expansion valve 13, described expansion valve 13, evaporimeter 12, compressor 11, condenser 14 is connected by pipeline 5 successively, described hot pipe system comprises heat pipe indoor heat exchanger 21, heat pipe chamber external heat exchanger 22, described heat pipe indoor heat exchanger 21 is connected with heat pipe chamber external heat exchanger 22, the air outlet of described evaporation fan 3 is just to evaporimeter 12 and heat pipe indoor heat exchanger 21, the air outlet of described condensation fan 4 is just to condenser 14, the positive opposite heat tube outdoor heat exchanger 22 of air outlet of described cooling blower 6.
The distance of described heat pipe indoor heat exchanger 21 and evaporation fan 3 is shorter with the distance of evaporation fan 3 than evaporimeter 12, indoor hot air first through heat pipe indoor heat exchanger 21, then through evaporator 12.
Outdoor cooling air first through heat pipe chamber external heat exchanger 22, then through condenser 14.
Described refrigeration air-conditioner subsystem also comprises temperature sensor, control device, and described temperature sensor is connected with control device, and described control device is connected with compressor 11, evaporation fan 3, condensation fan 4, cooling blower 6 respectively.Cold-producing medium inflatable conventional refrigerant, charging amount mates according to triangular web.
Described pipeline 5 can adopt copper pipe, aluminum pipe or rubber hose.
Evaporimeter 12 of the present invention and Indoor Thermal heat exchange of heat pipe 21 adopt superposition type to design, and share an evaporation fan 3.Be convenient to indoor air flow management and take the interior space little; And outdoor condenser 14 and outdoor heat exchange of heat pipe 22 adopt separation design.Can greatly reduce blower fan power consumption, when ambient temperature is higher, only open condensation fan 4; When ambient temperature is enough low, only open heat pipe cooling blower 6.
The present invention is compact to design, overall dimensions and normal base station or air conditioner in machine room similar.As long as outdoor environment temperature is suitable for, starts and just can run hot pipe system with the evaporation fan 3 of hot pipe system and cooling blower 4, substitute a part of refrigerated air-conditioning system refrigerating capacity, reduce the compressor 11 startup optimization time.Along with the reduction of outdoor environment temperature, compressor 11 can reduce running time further, until refrigeration air-conditioner subsystem stops completely, now can close condensation fan 4, only have hot pipe system cloud gray model.Control simple, operational parameter control only has indoor return air temperature, and according to the return air temperature that temperature sensor gathers, control device controls start and stop and the operating air velocity gear of start/stop of compressor, evaporation fan and condensation fan.
As long as the present invention in the data heart, control centre, industrial machine room, experimental center, electronic workshop, medicament compartment etc. has the room of the accurate demand for control of environment temperature can well to be applied, and can obtain good energy-saving effect.
