Description
Technical field
The present invention relates to air-conditioning technical field more particularly to a kind of methods and sky for preventing air-conditioning interior conduit temperature excessively high
Adjust device.
Background technique
For air-conditioning in heating process, it is excessively high often to will appear internal pipe temperature, and indoor pipe temperature sensing package is caused high temperature-proof occur
Protection, at this time existing solution be inner blower do not stop, outer fan parking, when internal pipe temperature is down to lower temperature outside blower again
It opens, is normally heated, at this time if outer blower stops too long, outer side condenser will appear the abnormal phenomenon such as defrost, and frequently
Numerous frosting defrost influences indoor heating capacity, while impacting to the reliability of compressor.
Summary of the invention
In order to solve drawbacks described above existing in the prior art, the present invention proposes that one kind prevents air-conditioning interior conduit temperature mistake
High method and air conditioner.
The present invention proposes a kind of method for preventing air-conditioning interior conduit temperature excessively high, air conditioner indoor unit heat exchanger into
The second heat exchanger that installation exchanges heat with the inlet ductwork on mouth pipeline；When then reaching preset temperature in heating operations
Second heat exchanger is connected to the export pipeline of the heat exchanger.
Further, when second heat exchanger is connected to the export pipeline, the export pipeline and described the are closed
One section to be in parallel between the import and export of two heat exchangers.
Preferably, the preset temperature is 65 DEG C.
The present invention also proposes a kind of air conditioner, makes to prevent air-conditioning interior conduit temperature mistake in heating with the aforedescribed process
It is high.
Further, the access of second heat exchanger is equipped with the first control valve.
Further, one section to be in parallel between the export pipeline and the import and export of second heat exchanger is equipped with the
Two control valves.
Preferably, first control valve is solenoid valve or electric expansion valve.
Preferably, second control valve is solenoid valve or electric expansion valve.
Preferably, second heat exchanger is heat exchanger tube, and the heat exchanging segment of the heat exchanger tube is around in inlet ductwork.
Preferably, the material of the heat exchanger tube is copper.
Compared with prior art, the present invention flows out export pipeline cold by adding the second heat exchanger with control valve
Matchmaker flow to the second heat exchanger when needing to cool down, and is cooled down by the heat exchange of the second heat exchanger to inlet ductwork, can make indoor pipe sense
The temperature that thermometer bulb detects reduces, and avoids enter into high temperature-proof protection.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is structure diagram of the invention.
Specific embodiment
The invention proposes a kind of methods for preventing air-conditioning interior conduit temperature excessively high, in the heat exchanger 1 of air conditioner indoor unit
Inlet ductwork 2 on the second heat exchanger 4 for exchanging heat with inlet ductwork 2 of installation；Then reach default temperature in heating operations
The second heat exchanger 4 is connected to the export pipeline 3 of heat exchanger 1 when spending, the refrigerant flowed out from heat exchanger is made to flow through the second heat exchanger 4
Cool down to inlet ductwork 2.By adding the second heat exchanger 4, the refrigerant for flowing out export pipeline 3 flow to second when needing to cool down
Heat exchanger 4 cools down to inlet ductwork 2 by the heat exchange of the second heat exchanger 4, the temperature drop that indoor pipe temperature sensing package can be made to detect
It is low, avoid enter into high temperature-proof protection.
In the present invention, when the second heat exchanger is connected to export pipeline, the import and export of export pipeline and the second heat exchanger is closed
Between be in parallel one section, so that the refrigerant flowed out from export pipeline is flowed completely through the second heat exchanger, improve changing for the second heat exchanger
The thermal efficiency shortens temperature fall time.
In the present invention, preset temperature is 65 DEG C.
As shown in Figure 1, the invention also provides a kind of air conditioner using the above method, including heat exchanger 1, connection heat exchange
The inlet ductwork 2 and export pipeline 3 of device 1, inlet ductwork 2 are equipped with the second heat exchanger 4, can exchange heat with inlet ductwork 2, the
Two heat exchangers 4 are in parallel with export pipeline 3 can be by refrigerant, and the second heat exchanger 4 is equipped with the opened or closed by controller
One control valve 5, when air-conditioning opens heating mode, the inlet ductwork 2 of the heat exchanger of air conditioner indoor unit flows into high temperature refrigerant heating,
Export pipeline 3 flows out low temperature refrigerant, when inner tube detects overheat triggering high temperature protection by indoor pipe temperature sensing package, opens the first control
Valve processed, the refrigerant for flowing out export pipeline 3 flow to the second heat exchanger 4, are cooled down by the heat exchange of the second heat exchanger 4 to inlet ductwork 2,
The temperature that then indoor pipe temperature sensing package can be made to detect reduces, and avoids enter into high temperature-proof protection.
In the present invention, the export pipeline 3 of heat exchanger 1 is additionally provided with the second control valve 6 with the section in parallel of the second heat exchanger 4, the
Two control valves 6 are closed when the first control valve 5 is opened, and improve the cold medium flux for passing through the second heat exchanger 4, improve heat exchange efficiency.
In the present invention, control valve be solenoid valve or electric expansion valve, using when electric expansion valve can control valve aperture,
Change the flow for entering the refrigerant of heat exchanger, carries out subtleer adjustment so as to the inlet ductwork temperature of heat exchanging device.
In the present invention, the second heat exchanger 4 is heat exchanger tube, and the heat exchanging segment of heat exchanger tube reaches heat exchange around in inlet ductwork 2
Effect, and the material of heat exchanger tube is the good copper of thermal conduction effect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
