Abstract
The present invention provides a kind of quick defrosting method, solves current finned heat exchanger defrost time length, the technical problem of effect difference, the present invention includes outdoor heat exchanger, the outdoor heat exchanger includes the heat exchanger tube positioned at outside and the fan on the inside of heat exchanger tube, it is characterised in that：During defrost, heat exchanger tube conveying thermal medium radiates in heat exchanger, and fan is out of service, dries to run to defrost from inside to outside by heat exchanger with rear fan and completes.Defrost effect of the present invention is good, and consumed energy is few, time-consuming short, and same power heat exchanger conventional method takes the completion of defrost in 7 minutes, and this programme only needs 3 minutes；By extraneous inwardly air draught antikinesis when being heated using fan is opposite（Dry from inside to outside）, equipment waste heat is blowed at heat exchanger tube and frosting, promotes heat exchange and defrost, and equipment dust stratification is blown out, dust removing effects are additionally played, are conducive to lifting means work efficiency and service life.
Description
Technical field
The invention belongs to heating equipment control method technical field, and in particular to a kind of suitable for the quick of outdoor heat exchanger
Defrosting method.
Background technology
Indoor end (includes but not limited to fan coil, grounding heat coil tube, low-temperature radiator, capillary network and radiation
Furred ceiling etc.) using the air-conditioning system (including multi-connected machine) of refrigerant, indoors during heating, outdoor heat exchanger is absorbed from room air
Heat, outdoor heat exchanger environment temperature is low, and the vapor in air can condense into frost and be attached to outdoor heat exchanger surface, so that shadow
The exchange capability of heat of outdoor heat exchanger is rung, in order to solve the problems, such as above-mentioned frosting, current defrosting method is generally commutated using four-way valve
Control, four-way valve commutates during defrost, and outdoor heat exchanger fan is out of service, and outdoor heat exchanger heat release, frost is melted, indoor heat exchange
Device absorbs heat, and run time is longer, causes fluctuations in indoor temperature larger, once cools down 8-10 DEG C；To shorten the defrost time, outdoor is changed
The fan of hot device, which also has to continue to suck external wind, to be run, but at this time since ambient temperature is relatively low, the frost removing on the outside of heat exchanger
Effect is poor, and defrost takes or not ideal enough.
The content of the invention
It is an object of the invention to provide a kind of quick defrosting method, it is quiet over more than 100 years to solve the heating equipments such as air-conditioning
The problem of state defrost, have the advantages that defrost time is short, and defrost effect is good.
To achieve these goals, the present invention is to realize by the following technical solutions：A kind of quick defrosting method, bag
Outdoor heat exchanger is included, the outdoor heat exchanger includes the heat exchanger tube positioned at outside and the fan on the inside of heat exchanger tube, defrost
When, heat exchanger tube conveying thermal medium radiates in heat exchanger, and fan is out of service, and heat exchanger tube is fully radiated at this time, subsequent wind
Fan is dried to run to defrost from inside to outside and is completed by heat exchanger.It is initiative to use bidirectional fan, during indoor heating by it is extraneous inwardly
Air draught is run, and when defrost dries operation from inside to outside, while promoting heat exchanger tube heat dissipation, equipment waste heat is blowed to frosting, auxiliary
Defrost, greatly improves defrost efficiency, saves defrost and takes and consume energy.
Preferably, after the fan is 20-40 seconds out of service, fan is dried and run 2-3 minutes from inside to outside by heat exchanger, changes
Frost is completed, and is met the use of most of usual heat exchanger, is taken shorter.
Preferably, the outdoor heat exchanger and a compressor, an indoor heat exchanger are linked to be circuit by medium pipeline, special
Not Shi Yongyu the heat utilization system, equally applicable air-conditioning system.
Preferably, the heat exchanger tube also connects a heat collector panel, and during defrost, the high-temperature medium of heat collector panel flows to heat exchanger tube,
Avoid consuming indoor heat excessively, reduce defrost and cause indoor temperature drop-out value.
Quick defrosting method of the present invention has the advantages that：
1st, defrost effect is good, time-consuming short, and same power heat exchanger conventional method takes the completion of defrost in 7 minutes, and this programme only needs 3 points
Clock；
2nd, defrost energy consumption is reduced, and the influence to indoor temperature reduces；
By extraneous inwardly air draught antikinesis when the 3rd, being heated using fan is opposite（Dry from inside to outside）, equipment waste heat is blowed to
At heat exchanger tube and frosting, promote heat exchange and defrost, and equipment dust stratification is blown out, additionally play dust removing effects, be conducive to be lifted
Equipment work efficiency and service life.
Embodiment
The technical solution in the embodiment of the present invention is clearly and completely described below, it is clear that described embodiment
Only part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this area
Art personnel all other embodiments obtained without making creative work, belong to the model that the present invention protects
Enclose.
The present invention provides a kind of technical solution：A kind of quick defrosting method, an outdoor heat exchanger and a compressor, a Room
Interior heat exchanger is linked to be circuit by medium pipeline, and the outdoor heat exchanger is included positioned at the heat exchanger tube in outside and positioned at heat exchanger tube
The fan of inner side, be air grid on the outside of heat exchanger tube, and fan is towards heat exchanger tube direction, said structure and current fin on the market
Type heat exchanger is consistent, and during defrost, heat exchanger tube conveying thermal medium radiates in heat exchanger, after fan is 20-40 seconds out of service, then
Fan is dried from inside to outside by heat exchanger runs 2-3 minutes to defrost completion.The heat exchanger tube also connects a heat collector panel, defrost
When, high-temperature medium flows to heat exchanger tube as caused by absorbing heat heat collector panel.Structure improvement need not be carried out to traditional heat exchangers, by fan
It is changed to either-rotation motor, you can using this defrosting method, greatly promote defrost effect, reduce defrost and take.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical solution, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
