In the past, the common problem in

In the past, the common problem in hvac design is that the air conditioning design scheme of the building project mainly copied the previous building model, making the Gross leasable area and heat load not match, therefore, the HVAC heating equipment does not meet the specific requirements of the building, resulting in higher investment, operating costs, energy consumption more serious phenomenon. The comfort effect of HVAC should be based on different building environment and building parameters to get accurate parameters. It is necessary to control the parameters of heat and cold and Dry and wet so as to match the comfortable degree of the building reasonably. At present, the air-conditioning system on the market has been adhering to the principle of energy conservation and environmental protection and low energy consumption, and its system configuration should be based on the actual power supply of the building's power system. Therefore, in the choice of air-conditioning, take into account the amount of pollutants it emits and the amount of electricity it consumes. In addition, the optimal design of water supply and drainage system can also realize electric energy saving, among which, the non-negative pressure water supply system can provide a larger reference for the design of water supply and drainage energy saving, and this type of water supply system can achieve the rational use of water resources, improve the utilization rate of water resources, thus effectively reduce the waste of water resources. To make full use of currently available clean energy, such as solar energy, wind energy, and so on, by designing solar energy systems that utilize solar energy as an alternative to the burning of fuels, in order to provide heating and heating services, can effectively reduce the consumption of fuel and pollutant emissions, truly achieve the goal of energy conservation and environmental protection. At the same time use wind energy in the building set vent, let the natural wind into the building to ensure the natural ventilation.
