Description

Carry Cooling and Heat Source and without auxiliary heat exchanging device and the Fresh air handling units of outer defeated hot and cold water

Technical field

The present invention relates to technical field that the is civilian and air-conditioner set in industrial project, particularly relate to and a kind ofly carry Cooling and Heat Source and without auxiliary heat exchanging device and the Fresh air handling units of outer defeated hot and cold water.

Background technology

The traditional energy that we use now is moving towards exhausted gradually, and economize energy and decreasing pollution are the matters of utmost importance that the whole world faces.Nowadays the energy of our country uses policy to be that exploitation develops simultaneously with saving, and saving is put in the first place.What the fast development along with national economy came is then the raising of living standards of the people, the application of central authorities' environment-friendly air conditioner is day by day universal especially, and then substantially improve the productive life environment of people, adjoint and raw energy consumption problem is also highlighting gradually, therefore no matter for the developer of central air-conditioning, or for vast social consumption person, all also should must pay close attention to the degree that it accomplishes in power saving, and then while constantly improving air conditioning function, focus on the transformation innovation of power-saving technology, constantly to reduce investment, operating cost and resource loss, this is of great significance for raising China central air-conditioning energy technological self-innovation.

One, traditional air conditioner Situation of Heat Consumption

Because the awareness of saving energy of technical merit finite sum is not strong, the energy consumption of air-conditioning in each application is caused constantly to increase, wherein serious with building field.Interrelated data shows, and China's building energy consumption accounts for 38% of global energy consumption, and in the building having central air-conditioning, the energy consumption of central air-conditioning accounts for 70% of total energy consumption.Wherein, air-conditioner set power consumption accounts for about 50% of the total power consumption of air-conditioning, and the power consumption of fan coil end-equipment accounts for the 10-20% of the total power consumption of central air-conditioning.Because the actual heat load of central air-conditioning of major part building is low more than design (calculated) load within the overwhelming majority time, and main frame, subsidiary engine and end comfort level three fail to realize reasonable dynamic adjustments, cause system effectiveness low, waste of energy is serious, therefore fills air-conditioned building energy consumption and also can increase year by year.

Two, the disadvantage of traditional air-conditioning system
