Key Points of Installation Technology and Analysis of Energy Saving Measures on HVAC Equipment

HVAC equipment is very concerned in the current equipment operation process.Its safety,reliability and comfort will have a greater impact on the production and life of common people.In some projects,there are some problems in the installation of HVAC equipment,such as imperfect installation scheme,low installation quality and random selection of equipment parameters.These seriously affect the normal operation of the equipment,and it is not easy to achieve energy saving of HVAC equipment.In the future installation of HVAC equipment,it is necessary to continuously optimize the HVAC equipment installation system,fully compare the reliability and feasibility of the equipment installation scheme,and strengthen the application of energy-saving technology of HVAC equipment.In this way,the use cost of the equipment can be reduced and the comprehensive quality of the equipment can be improved.Therefore,this paper discusses this further and puts forward reasonable suggestions.

Analysis of Construction Quality Problems of Indoor Drainage Installation

If the indoor drainage pipe is blocked and the drainage is not smooth,sewage and pollutants will enter the room and endanger human health.If the pipeline is blocked as a result,a certain intensity of water pressure may be brought,which may cause pipeline leakage.In this article,we will analyze and explain the quality problems that often occur during the construction process due to the blockage of the internal drainage pipe,and propose appropriate methods and solutions to improve the quality of the project.

Triple broadband compact planar inverted F antenna for WLAN and WiMAX

This article proposes a novel antenna structure by slot loading method based on the planar inverted F antenna （PIFA）, which is fed by coaxial probe. The antenna structure consists of a new and flexible slot array including five slots. To reveal the mechanism of slot loading in creating new and broad frequency band, the article discusses the performance of the five slots in detail. Simulations with Ansoft HFSS 10.0 indicate that the - 10 dB relative impedance bandwidth can reach 17.2%, 8.9% and 12.1% that covers 2.40/3.30/5.15/5.725 GHz wireless local area network （WLAN） and world interoperability for microwave access （WiMAX） bands. Meanwhile, the antenna has stable radiation pattern, high gain and low profile. Especially, the slot array is flexible and capable of being realized in various application cases. Actually the design reaches broadband, multi-band, miniaturization, high gain and is easy to fabricate.

In this paper, we focus on antenna array design for mobile phone with finite volume and propose a novel antenna element structure by capacitive feeding and capacitive loading method based on the planar inverted F antenna （PIFA）. State-of-the-art development on this issue is reviewed. Then, a novel capacitively fed and capacitively loaded PIFA structure is proposed and studied. The results of the experiments showed that our structure can reduce the coupling of antenna elements from - 13.4 dB to -24.5 dB. Finally, a design with a bandwidth of 100 MHz centered at 2.35 GHz and envelopment correlation coefficient of 0.01 2 is provided and the diversity performance of the dual-element modified PIFA array is evaluated in both simulation and measurement. In a word, our novel design reaches broadband, miniaturization, high isolation and offers excellent diversity performance.
