Smart home technology has developed rapidly. In the development of smart home technology, air conditioner plays a vital role. It improves indoor thermal comfort and air quality, providing a comfortable living environment and protecting the health of the occupants. For smart home algorithms, active smart control of residential air conditioning is the most important component.

In the field of smart home, accurately predicting the potential use behavior of users is a key technology to improve the user experience. Improper air conditioning operation will reduce the effect of air conditioning, increase energy consumption and even reduce the service life of air conditioning.

The double-bile single-tube electric water heater is an economical and efficient design scheme, which reduces the manufacturing cost of the water heater by heating the water in two inner tanks simultaneously through one heating tube. However, there is a problem in this design, that is, the water temperature of the upper and lower gallbladder is very different. Through computer simulation and experimental test, it is found that the structure of the inner tube, the length and bending mode of the heating tube and the power of the heating tube are the main factors affecting the temperature difference between the upper and lower gallbladder. By optimizing these parameters, the temperature difference between the upper and lower gallbladder can be significantly reduced, thereby improving the user experience. Take the following measures in the design process: first, appropriately increase the inner diameter of the liner connecting pipe, greater than 45 mm is preferable; secondly, the structure of the heating tube is changed to make it focus on the connecting port, which is more in line with the demand of hot water circulation; finally, the reasonable choice of heating tube power as far as possible to control between 1500 W~3000 W, to avoid too large or too small. The research result has important practical significance for improving the user experience of double-bile single-tube electric water heaters and promoting their popularization in the market.

The comfort of air conditioning heating has increasingly become the focus of attention of users. However, air conditioning heating generally suffers from long heating waiting times and large vertical temperature differences. To all the phenomenon above, the effects of ambient temperature, heat leakage and air outlet angle on heating performance are analyzed through experiments, and simulation software was used to simulate the differences in room temperature rise rate and vertical temperature difference under different air outlet angles. Considering the room temperature rise and vertical temperature difference, it is concluded that when the air supply angle is 30°, the room temperature rises faster and the vertical temperature difference is small, making it the optimal air outlet angle. Which provides an important basis for the design of the heating outlet angle of wall mounted air conditioning.

Aiming at the high frequency noise peak prominent problem of reciprocating compressor, the mechanism of high frequency noise generation and control measures of reciprocating compressor used in refrigerator were studied.

The modal superposition frequency response simulation method was used to improve the design of the structural parameters of the key transmission path, and finally the high-frequency noise problem was located and optimized from the perspective of the vibration transmission path. The results show that among the high frequency components of vibration transmission from the movement to the bottom of the compressor housing, the vibration transmission proportion of the compressor oil pool is the highest, followed by the movement support spring, and the vibration transmission of the compressor tube is the least. The problem of high-frequency noise of the reciprocating compressor is solved from the point of view of the transmission path through the optimization design of the oil injection volume of the oil pool.

Leakage inside the compressor pump is one of the main factors affecting compressor performance. Through simulation of the performance of rotary compressors, it is found that piston end face leakage has a significant impact on compressor performance. At the same time, it is analyzed that the reduction of piston end face clearance can reduce end leakage and greatly improve compressor performance. Therefore, a piston end face forced oil supply sealing structure is proposed to reduce the actual leakage clearance of piston end face during compressor operation and improve compressor performance. Based on theoretical oil supply pressure, volumetric flow rate, and fluid simulation analysis, the structural form and dimensions of the forced oil supply seal were determined, ensuring the effectiveness of the forced oil supply seal structure without affecting the reliability of the compressor. Finally, it was confirmed through experiments that the forced oil supply seal structure of the piston end face can improve the performance of the compressor.

In order to improve the simulation precision of nonlinear materials, focuses on the constants of the Mooney-Rivlin constitutive model for hyperelastic materials, aiming to compare whether the constants obtained from uniaxial tensile and compressive tests are consistent. Firstly, standard tensile and compression splines are made and subjected to uniaxial tensile and uniaxial compression tests to obtain deformation tension or pressure data. Secondly, process the data to obtain the true stress-strain curve. Then input the stress-strain curves obtained from tension or compression into the simulation software for data fitting to obtain the Mooney-Rivlin model constants C10 and C01, and compare the consistency of the two sets of constants. Finally, a nonlinear simulation analysis is conducted to compare the stress-strain curve obtained from the simulation with the test results to verify the accuracy of the model. The results show that the model constants obtained from tensile and compressive tests are inconsistent, and the type of test to be adopted needs to be determined based on the specific stress situation, which provide experimental basis for subsequent material definition and simulation work.

In the portable air conditioner (PAC), the condensate is sprayed on the high temperature fin of the condenser by the centrifugal atomization of the water-wheel, and then discharged through the exhaust duct after heating. But its atomization capacity is limited, and artificial drainage is still needed under high-humidity conditions. A new atomization method (micro-hole high-speed jet atomization/nozzle atomization) is proposed, and we test the no-drainage capacity and the performance of PAC under high humidity conditions (t=27℃, RH=90%). The influences of water-wheel atomization and micro-hole high-speed jet atomization on the condensate removal capability and refrigeration system of PAC is compared. Compared with no condensate, the result shows that the refrigerating capacity increases by 3.16% (water wheel is 1.77%) and the Energy Efficiency Ratio (EER) increases by 11.70% (water wheel is 6.62%), and the continuous running time can be achieved for 24 h (water wheel is 6 h) for nozzle atomization. Therefore, the use of nozzle atomization has more advantages in improving the energy efficiency and no-drainage capacity of the whole machine.

The suction gap at the bottom of the stationary disc in the scroll compressor is designed to increase the suction flow rate of the compression chamber and have a significant impact on the suction process and performance. To study the influence of suction gap, CFD simulation was used to study the effects of different suction gaps on the unsteady pressure field, flow distribution, and performance. The results showed that the suction pressure and flow rate showed unsteady fluctuations. As the suction gap decreased, the suction pressure continued to increase, and the suction flow rate continued to decrease. The increase in suction pressure led to a decrease in compressor power and an overall increase in energy efficiency. Through whole machine testing, it was found that under DOE-B condition, when the suction gap was from present to absent, the cooling capacity decreased by 0.70%, the input power decreased by about 1.01%, and the energy efficiency increased by about 0.32%. This verified the effectiveness of the established CFD simulation method, and the research can provide guidance for the optimization design of the suction process of scroll compressors.
