Central air-conditioning energy-saving scheme
Release time：2019-09-06 | Source：HUA LI JI DIAN.Central air-conditioning system operating energy consumption is the most important energy consumption link in most public buildings, building energy consumption in the central air-conditioning system energy consumption of about 50%-70%, the recent national energy-saving targets and people's awareness of energy conservation gradually enhanced, reduce energy consumption enterprises not only increase disprofitability, but also advocate the national policy of energy conservation and emission reduction.
Central air conditioning system main power-consuming equipment:
Central air-conditioning air-conditioning main equipment, fan coils, refrigeration cooling pumps, cooling water towers, hot and cold pressurized pumps, heat pump hot water units.
Central air-conditioning equipment energy-saving solutions:
2.1、Host energy-saving transformation
Central air conditioning host recommended the use of heat recovery or environmental refrigerant models, for the installed central air conditioning system of the old system, if the host is screw or piston model, and is R22, R407C, R134a refrigerant host can implement waste heat recovery technology transformation, so that not only get free living hot water, But also reduce the host unit energy consumption, R134A environmental refrigerant now does not have manufacturers bring their own heat recovery, can carry out heat recovery transformation, but the heat production is not R22 refrigerant more, there is a heat recovery function needs to add additional heat exchange equipment to achieve.
2.2、Water pump energy-saving transformation
Refrigeration, cooling water pump recommended variable flow of variable-frequency energy-saving technology transformation, so that the entire central air-conditioning water system on-demand supply, so that the water pump energy consumption can be saved by more than 40%.
2.3、Energy-saving transformation of cooling tower
Cooling tower fans are not recommended for conversion technology after the conversion of cooling water, unless the capacity of the cooling tower exceeds the host configuration. Coil fan has automatic temperature control function, no need for technical reform, if the concentrated cooling of the wind cabinet is another matter, but the wind turbine pipe must be installed proportional control valve, when no one uses the case does not waste the flow of frozen water, that is, reduce the loss of cold, but also save the frozen water pump electricity.
Cold water, hot water pressurized water pump must take variable frequency constant pressure control, so that the system water flow on demand supply. Cold water pressurized pump if the situation allows, can also use no negative pressure variable frequency constant pressure water supply, this technology than the traditional variable frequency constant pressure water supply also save more than 60% of electricity.Huali electrical and mechanical has always adhered to the principle of science and technology energy conservation, with the most applicable programs and the lowest cost to achieve the best results of energy conservation.
