person current capacity many, operation time long, management complex characteristic, causes the movement energy consumption to be quite high, the commercial construction air conditioning energy consumption nearly occupies its total energy consumption 50%. The central air conditioning design capacity is according to the biggest load computation, but in a major part building year only has several dozens days time central air conditioning to be at the biggest load condition. The central air conditioning cold load throughout is in during the dynamic change, like every day sooner or later, each season in turn, every year samsara, the environment and the humanities condition, real-time will be affecting the central air conditioning cold load. General, the cold load undulates in 5 ~ 60% scope, the majority building every year at least 70% is in this kind of situation. But the majority central air conditioning actually opening machine capacity far is smaller than the installed capacity, if take the most greatly cold load as the maximum work rate actuation, creates between the actual need cold load and the maximum work rate output contradiction, actually creates the huge energy waste, the national economy and the society develops for brings the very tremendous influence. This has brought the stern topic for the central air conditioning energy conservation control, also gives the general energy conservation control domain the worker brought enormously has displayed the talent the space. The power load gap increases, the electric power supply tense aspect with difficulty obtains in recent years relaxes. Therefore, energy conservation in particular electricity saving, not only has the significant social significance moreover to have the urgent practical significance. Positively studies the development promotion green environmental protection new air conditioning technology and the equipment, the suppression air conditioning energy consumption increases, has become the building warmly to pass air conditioning domain urgent and the popular research topic. The dependence technology innovation, the system innovation, the energy conservation falls consumes, enhances the energy use efficiency, guaranteed are least in the "energy consumption, in the environmental pollution smallest" foundation, realizes the "energy conservation first, structure many Yuan, environment friendly" energy developmental strategy. In our telecommunication production, air conditioning energy conservation supervisory work weaker, the energy waste phenomenon is serious, therefore strengthens air conditioning the maintenance management and the technological transformations, may achieve the energy conservation the goal. Looked from the air conditioning pressure enthalpy chart that, only has the movement in the best operating mode and the condition, can display air conditioning the biggest refrigeration quantity, achieves the air conditioning energy conservation the goal. If the inflation valve oil stops up seriously, carries on the clean using the absolute ethyl alcohol, again severely newly installs; Loses the adjustment function the expansion valve to be supposed to replace. The air conditioning energy conservation, our maintenance department should from the movement cost, the maintenance maintenance aspect angle carry on the consideration. 2. air conditioning energy conservation system research survey 1) through the load control, achieves the energy conservation goal. (a) The burning hot season new atmosphere load occupies the entire cold load 25-40%, reduces the new atmosphere load, reduces the new atmosphere energy consumption, the choice smallest essential new amount of wind, also can achieve the goal. But the new amount of wind smallest supply on the one hand the country had the standard, moreover the new amount of wind insufficient will affect the air quality, will endanger the human body health. (b) Outside the optimized construction the surrounding protection structure energy conservation design, uses the heat preservation thermal insulation material technology, reduces the air conditioning load, the realization construction energy conservation, but simultaneously also causes the building cost rise, the promotion to receive the certain limit. 2) gathers can the air conditioning. Gathers coldly through the ice, avoids the daytime to use electricity the peak, at night stores up the air conditioning freezing water refrigeration, daytime does not start the air conditioning main engine only to use the aqueous system to circulate. This method itself certainly does not conserve energy the province electricity, but optimized the electrical network power supply, to already implemented the time sharing electrovalence the area, played "to economize does not conserve energy" the role, had the area promotion significance. 3) water source heat pump. Is opposite says to the air and the soil, the water is the most ideal spatial transfer cold heat source, the water source heat pump also therefore has the environmental protection, is highly effective, the energy conservation and so on the multitudinous merit, but our country water source heat pump engineering research is not very mature, compares with some developed countries also has the certain disparity. At the same time, the water source heat pump although has very many merits, but receives the geology, the environment, the policy and so on the limit quite is also big, this caused the water source heat pump to be restricted in an our country more widespread application.
