Commercial Integration of Shanghai Lingge Air Conditioning Technology Engineering Co., Ltd.

The central fresh air system can independently carry out indoor air replacement, purification and flow system. While eliminating indoor polluted air, we can import 100% natural fresh air, and send the fresh air indoors after multiple treatments such as intermediate filtration, sterilization, oxygenation, disinfection and preheating (when the outdoor air is cold).

Working principle of central fresh air system The transmission mode of fresh air is displacement, not the internal circulation principle of air conditioning gas and the bad practice of mixing old and new gases. Outdoor fresh air will be automatically sucked into the room through negative pressure, and it will be automatically dedusted and filtered when it enters the room through the fresh air outlet. At the same time, the corresponding indoor pipes are connected with the exhaust ports of several functional rooms, and the formed circulation system will take away the indoor exhaust gas and concentrate it on the exhaust port to "exhale", but the exhausted exhaust gas will not be recovered, and the old and new air will form a good circulation. Moreover, considering the saving and reuse of energy, the exhausted air is heat recovered, and the recovery rate reaches over 80%, which is used as new energy. Healthy and comfortable heating methods will help you get twice the result with half the effort.

With the continuous improvement of living conditions, people put forward new requirements for indoor heating. Many projects use low-temperature floor radiant heating system instead of ordinary radiator heating, which overcomes the problems of high energy consumption, poor comfort, difficulty in household metering and room occupation. Summarize some experiences in the construction process so as to be better applied in other similar projects.

Low-temperature hot water floor radiant heating is a heating system that uses the ground inside the building. The plastic pipe is laid in the cast-in-place concrete layer of the floor slab, with the hot water temperature not higher than 55℃ and the working pressure not higher than 0.4 MPa. The system takes the whole floor as the radiation surface, and the floor heats the surrounding air through convection heat exchange, and at the same time, it also carries out radiation heat exchange with human body, furniture and surrounding maintenance structures, thus increasing its surface temperature, and its radiation heat exchange accounts for more than 50% of the total heat exchange. It is an ideal heating system and can effectively solve the problems existing in radiator heating. The central dust removal system consists of a dust collection host, a pipe network, a dust collection socket and a dust collection component. The vacuum cleaner is located in the computer room, balcony, garage and equipment room (or outdoor) of the building. The host computer is connected with the suction port of each room through network management. When cleaning, the dust collection assembly is inserted into the suction port, and harmful gas and dust are sucked into the large-capacity garbage bag through the vacuum dust collection pipeline. Simple operation, avoiding the influence of noise on the room, avoiding the secondary pollution caused by dust, and completely eliminating the pollution of small size. The central dust collection system can be divided into two types from the use point of view: commercial type and domestic type. Operationally, it can be divided into centralized management and household management. According to the development of system switch starting mode, it can be divided into no power supply pressure wave starting type and power socket starting type. Using central dust collection system in high-grade office buildings, high-rise apartments and hotels greatly reduces the cost of property management, increases the use function of buildings and brings healthy, quiet and comfortable living space for owners.

Working principle of central dust collection system: PVC pipe network is used to connect the automatic interface designed and configured on the floor or wall of the house with the working host installed outside the living area (such as computer room, basement or garage). When the vacuum cleaner hose is plugged into the interface system, it will automatically start working. All dust and debris will be absorbed and discharged outside the living area. In today's information age, people's real-time communication is more and more frequent.

Business conference system is the most basic conference system, which consists of microphone, player, audio and desktop display equipment (such as desktop intelligent terminal and LCD). The combined application of these devices can also be said to be a conference system, which plays the role of transmitting sound, displaying and amplifying sound, and achieves the effects of watching, listening and speaking.

Widely used in: monitoring, command and dispatch systems, public security, fire protection, military, meteorological, railway, aviation and other monitoring systems, video conferencing, inquiry systems. With the development of science and technology, more and more new technologies are applied to electronic conference system. Video conference is the product of the combination of audio conference system, communication and Internet technology.

With China's entry into WTO, all enterprises and institutions are facing greater business opportunities and challenges. Video conferencing can improve your communication efficiency and work effect in many ways.

The networking structure of the video conference system is different with the different ways of participants' participation. Generally speaking, there are two networking structures: point-to-point networking structure and multipoint conference networking structure. The so-called background music system is an indispensable part of smart home. That is to say, music lines can be laid in any room, including living room, bedroom, kitchen and bathroom, and people can hear beautiful background music in each room through one or more sound sources.

Create a relaxed and harmonious atmosphere and direct evacuation in case of emergency. With the development of science and technology and the maturity of enterprise management mode, highly scientific enterprise management has become a powerful guarantee for the survival of enterprises. Carelessness in any link of public security, personnel management and enterprise secrecy may cause losses to enterprises. On a series of issues such as economic benefits, scientific and technological achievements and internal affairs management, Linger's access control attendance system provides a strong guarantee for this.

Perfecting safety precautions and strengthening personnel management in enterprises.

Security alarm system is the "brain" of enterprise security system, which consists of various sensors, function keys, detectors and actuators. Alarm functions include fire prevention, theft prevention, gas leakage alarm and emergency help. The alarm system adopts advanced intelligent control network technology, which is managed and controlled by microcomputer to realize automatic alarm of accidents such as robbery, theft, fire, gas and emergency help.

Solar energy heating system refers to the system that uses solar energy as the heat source of heating system and solar energy collector to convert solar energy into heat energy, which is used for building heating in winter and other heat consumption throughout the year. The solar floor heating system consists of a heat collector, a heat storage water tank, a domestic hot water system, a heating system (floor heating and radiator), auxiliary energy heating equipment and a control system.

Working principle of solar energy heating system

The working principle of solar heating system is to heat the medium (usually water) through vacuum tube collector, and then store the heat in the heat storage tank through circulation system. After the temperature of the water tank reaches a certain temperature, the heat is transferred to the geothermal coil or radiator through the heat exchanger, and then the ground/radiator evenly dissipates heat indoors, saving energy, and the service life can be up to 50 years.
