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.
4) in the central air-conditioning system inpidually consumes energy the equipment energy conservation transformation. (a) Air blower and water pump general frequency changer velocity modulation energy conservation, this is at present uses more technologies. This method simple practical, electricity saving effect obvious, but product and so on water pump, air blower is the system auxiliary engine partially, occupies the overall system energy consumption approximately is 40%, therefore the excavation space is limited. (b) The refrigeration main engine, the refrigeration unit's power consumption holds the very big share in the air-conditioning system, saves this part of consuming energy is the entire air-conditioning system economy movement key. At present generally all uses reduces the indoor temperature standard, enhances the cold water temperature and so on the measure realization refrigeration main engine energy conservation.
