Description
Technical field
It is to be related to a kind of to determine that two air-conditioner outdoor units are horizontally disposed optimal in groove the present invention relates to field of air conditioning
The method of mounting distance.
Background technology
With the fast development of China's economy, people's living standards continue to improve, requirement of the people to indoor environment
More and more higher, air-conditioning start progressively to be dissolved into our daily life as the important means for improving indoor comfort.According to
The statistics of State Statistics Bureau shows that the air-conditioning of the average each one hundred houses family of China town dweller was gathered around from 2000 to 2009
The amount of having rises to 106.84 via 30.8, and domestic market air-conditioning sales volume in 2016 is up to more than 4,700 ten thousand, it can be seen that, state
Interior domestic air conditioning usage amount is increasing year by year.
But air-conditioning considerably increases energy resource consumption while comfortableness is brought to us.By taking town-property as an example,
Air-conditioning total power consumption is 25,000,000,000 kWh within 2004, and this numerical value has exceeded 40,000,000,000 kWh within 2008.The increase year by year of air conditioning energy consumption
Its proportion in total energy consumption is built constantly is increased, therefore reduce air conditioning energy consumption, improve its operational efficiency and built as reduction
Build the important channel of operation energy consumption.At present, it is many to build in order to which attractive in appearance all build has building groove, and by blinds on the outside of groove
Block, when building an outdoor seat in the plane in groove while arranging more air-conditioner outdoor units and smaller outdoor unit spacing, air conditioning chamber
The ventilation of outer machine can become obstructed because of narrow space, therefore the radiating of outdoor unit and runnability can be affected.Institute
When building two air-conditioner outdoor units of arrangement in groove, to determine rational horizontally disposed distance.
The content of the invention
The purpose of the present invention is to make air-conditioner outdoor unit radiating abundant, improves the Energy Efficiency Ratio of air-conditioning system, saves the energy and carry
For a kind of method for the optimal mounting distance for determining that two air-conditioner outdoor units are horizontally disposed in groove.
Present invention determine that the method for two air-conditioner outdoor units optimal mounting distance horizontally disposed in groove, specific steps
It is as follows：
1）Determine horizontally disposed spacing ds
According to two air-conditioner outdoor units actual installation condition horizontally disposed in groove, the value of horizontally disposed spacing is determined
Scope is 40mm-110mm；
2）Sample data is obtained by experimental method
According to step 1）Identified two air-conditioner outdoor units spacing value horizontally disposed in groove is：40mm, 50mm,
70mm, 90mm, 110mm, tested respectively, obtain the return air temperature of every outdoor unit, the power consumption of compressor and air-conditioning system
The refrigerating capacity of system；
3）Based on step 2）Experimental data：Outdoor unit EAT is with the variation diagram and Energy Efficiency Ratio of horizontal range with horizontal range
Variation diagram carry out statistical analysis, and then obtain two air-conditioner outdoor units optimal mounting distance horizontally disposed in groove, most
Good mounting distance ds is 70mm.
The present invention optimal mounting distance horizontally disposed in groove to two air-conditioner outdoor units has done systematic research, point
The trapped energy theory of other return air temperature and air-conditioning system under two outdoor unit difference spacing is studied, by score
Analysis, finds out two air-conditioner outdoor units optimal mounting distance horizontally disposed in groove.
The present invention determines experiment condition with orthogonal experiment method, sample data is obtained by experimental method, with statistical analysis
Method obtain two air-conditioner outdoor units optimal mounting distance horizontally disposed in groove.
Compared with prior art, benefit effect of the present invention is as follows：
1）Determine that two air-conditioner outdoor units optimal mounting distance horizontally disposed in groove advantageously reduces the return air temperature of air-conditioning
Degree, so as to reach the purpose of energy-conservation；2）Present invention determine that optimal mounting distance, be advantageous to improve air-conditioning system Energy Efficiency Ratio
EER, and then save the purpose of the energy.
Brief description of the drawings
Fig. 1 is two air-conditioner outdoor units horizontally disposed schematic diagram in groove；
Fig. 2 is variation diagram of the outdoor unit EAT with horizontal range；
Fig. 3 is variation diagrams of the EER with horizontal range.
Embodiment
The present invention will be further described below：
1）Determine horizontally disposed spacing
As shown in figure 1, according to two air-conditioner outdoor units actual installation condition horizontally disposed in groove, determine horizontally disposed
Spacing, value is 40mm, 50mm, 70mm, 90mm, 110mm to the horizontal range of two outdoor units successively.
2）Sample data is obtained by experimental method
The level interval of two outdoor units that analysis obtains more than is deployed to test successively, in experimentation outdoor unit away from wall away from
From control in 150mm, the distance controlling away from blinds blocks blinds and uses aluminium alloy hundred in 250mm, groove height 1200mm
Leaf, blinds spacing are 100mm, and width of blade 50mm, the control of blinds aperture is at 10 °.Indoor and outdoor side temperature is respectively set to 35
DEG C, 25 DEG C, air-conditioning design temperature be 18 DEG C.Tested by the change of two outdoor unit horizontal ranges, obtain experiment sample
Data.
3）Based on step 2）Experimental data carry out statistical analysis, and then it is horizontal in groove to obtain two air-conditioner outdoor units
The optimal mounting distance of arrangement.Optimal mounting distance ds is 70mm.
Based on experiment sample data, the return air temperature and trapped energy theory of air-conditioning system are analyzed.It can be seen by Fig. 2
Going out, the return air temperature of outdoor unit 1 is consistently greater than the return air temperature of outdoor unit 2, and with horizontal range ds increase, outdoor unit
1st, 2 return air temperature all has a declining tendency, and occurs maximum fall when horizontal range increases to 70mm by 50mm, respectively
It is 1.78 DEG C and 0.61 DEG C, reaches minimum in 70mm.As seen from Figure 3, the trapped energy theory of air-conditioning 1,2 is with level
Distance ds increase and increase, reach maximum in 70mm.Therefore, when two outdoor units are installed with horizontal arranging mode,
Optimal mounting distance be 70mm, and outdoor unit ambient thermal conditions now are advantageous to the operation of outdoor unit, and air conditioner is with higher
Energy Efficiency Ratio.
