Description
Technical field
It is especially that a kind of multi-online indoor machine heats the control after temperature is shut down the present invention relates to the control method of air-conditioner
Method processed.
Background technology
Multi-connected air conditioner is general to drag multiple indoor sets by one or more outdoor unit, and each indoor set is to a room
Heated.One heat detector can be set at the return air inlet of each indoor set.In a heating mode, user can set a room
Such as 28 DEG C of target temperature.Once the heat detector of certain indoor set detects temperature reaches target temperature, then this indoor set is shut down.
Because the outdoor unit of multi-connected machine is required to drag multiple indoor sets, after certain indoor set to temperature, remaining indoor set is likely to also need
Work, so when indoor set is shut down, the compressor of outdoor unit is not shut down.And because compressor works on, therefore to avoid height
Pressure failure, the electric expansion valve of the indoor set of shutdown will not be completely closed, and be to maintain a less standby aperture, such as 40~
60 steps.So, the detailed process that the indoor set of multi-connected machine is shut down to temperature is that the blower fan of the indoor set is closed and electric expansion valve is closed
It is small to standby aperture.
And the control mode restarted is also fairly simple after the multi-online indoor machine of prior art is shut down to temperature, i.e. heat detector inspection
The temperature for measuring is less than target temperature, then indoor set restarting.This there is a very big defect, i.e. indoor set shutdown
Afterwards, because electric expansion valve still has aperture, therefore the gaseous coolant of a small amount of HTHP still can be by the coil pipe of indoor set, disk
Pipe radiations heat energy causes that the heat detector temperature of the indoor set rises so that the temperature of indoor set heat detector collection is significantly larger than room
True temperature, lead to not triggering air-conditioning and restart and heat in time, and then cause whole room temperature continuous decrease, allow people to feel
It is cold uncomfortable.
The content of the invention
The technical problem to be solved in the present invention is to provide one kind air-conditioning when room actual temperature is eligible and can weigh in time
Open and heat, so that it is guaranteed that room temperature will not decline excessive multi-online indoor machine heats the control method after temperature is shut down.
Technical solution of the invention is to provide a kind of multi-online indoor machine and heats the control method after temperature is shut down,
It is comprised the following steps that:After indoor set heat detector reaches target temperature, the blower fan of the indoor set is closed and electronic expansion valve regulation
To standby aperture;And blower fan close after, at interval of a stand-by time Ta after, by blower fan with low wind shelves operation one detection time
Tc, and the temperature of heat detector is monitored in detection time Tc, and whether real-time judge heat detector temperature is less than target temperature, such as
Fruit is that electric expansion valve then is tuned up into normal aperture, in case the mode of cold wind is run with normal wind shelves again after starting blower fan;Such as
Fruit heat detector temperature in whole detection time Tc is not less than target temperature, then blower fan is continued into shutdown after detection time Tc
And electric expansion valve is stilled remain in into standby aperture;Continue to be spaced next stand-by time Ta, then carry out detection next time
Process.
The principle of the control method is, after indoor set is shut down to temperature, at interval of a stand-by time, just by blower fan with low
Wind shelves one detection time of operation so that air and space air forced heat-exchanging near air-conditioning heat detector, to correct heat detector temperature
Difference between degree and room true temperature, once find that heat detector drops to target temperature at a temperature of measuring in detection time
Hereinafter, then triggering indoor set turns back on operation, if it find that the temperature of heat detector measurement is above in whole detection time
Target temperature, then illustrate that room true temperature does not reach indoor set still and restarts condition, therefore indoor set continues to shut down, next at equal intervals
After individual stand-by time, the low wind shelves forced heat-exchanging of blower fan is driven again, detect whether that meeting indoor set restarts condition again, such as meet
Then indoor set start, is unsatisfactory for, and continues standby, is then detected next time, reciprocal with this.
Using above method, multi-online indoor machine of the present invention heats control method and prior art phase after temperature is shut down
Than with advantages below:
The control method solve the heat detector of indoor set due to persistently there is high temperature refrigerant to pass through, caused by radiation heat release temperature
Height is spent, causes heat detector excessive with room true temperature difference, cause indoor set in time to restart the problem for heating, passed through
The forced heat-exchanging of indoor fan compartment so that the temperature infinite approach room true temperature of heat detector detection, it is to avoid interior
Machine heats caused room temperature continuous decrease due to that can not restart in time, optimizes Consumer's Experience.
Specific embodiment
Multi-online indoor machine of the present invention heats the control method after temperature is shut down, and it is comprised the following steps that.
After indoor set heat detector reaches such as 28 DEG C of target temperature, the compressor of the multi-connected machine does not shut down and the wind of the indoor set
Office closes and electronic expansion valve regulation is to standby aperture such as 40~60 steps.
And blower fan close after, at interval of a stand-by time Ta after, by blower fan with low wind shelves operation one detection time Tc,
And in detection time Tc monitor heat detector temperature, and real-time judge heat detector temperature whether be less than target temperature.Wherein,
Ta takes 5~10 minutes, preferably 8 minutes, and Tc takes 30~60s, preferably 40s.
If heat detector temperature occurs in that the situation less than target temperature in detection time Tc, electric expansion valve is adjusted
Normal aperture is arrived greatly, in case the mode of cold wind is run with normal wind shelves again after starting blower fan;Indoor set restarts heating operation,
Until arriving temperature shutdown next time.
The control mode of described anti-cold wind refers to that the temperature of indoor coil is detected with air-conditioning master controller, is only ensured
After such as larger than 30 DEG C higher of indoor coil pipe, blower fan just starts, and otherwise blower fan does not start.And above-mentioned normal aperture and normal
Wind shelves be most conventional control mode, usually air-conditioning master controller according to delivery temperature, the degree of superheat, pressure at expulsion etc. according to warp
Test what is chosen and judge, aperture and the wind shelves of different unit electric expansion valve are all different.If electric expansion valve is with 120~160
Step operation, and blower fan is run with apoplexy shelves.
If heat detector temperature is not less than target temperature in whole detection time Tc, by wind after detection time Tc
Machine continues to shut down and electric expansion valve is stilled remain in into standby aperture not change.Then, fan parking and electronic expansion are kept
The constant state of the standby aperture of valve simultaneously continues next stand-by time Ta, then carries out detection next time, i.e., low wind shelves are transported again
One detection time Tc of sector-style machine, judges whether situation of the heat detector temperature less than target temperature occur, if it did not, indoor set
The stand-by time Ta that shuts down is continued to, then carries out detection process next time, it is reciprocal with this.
