Abstract
The utility model belongs to the field of energy-saving equipment, and particularly relates to a variable frequency energy-saving control device for a pump and a blower of an air conditioner. A compressor is connected with a cooling water heat exchanger and a chilled water heat exchanger respectively; a cooling water circulation system and a chilled water circulation system are connected to form a central air conditioner system; and the blower and a water pump are controlled by a frequency converter. By developing a reasonable variable frequency control operation scheme of the blower and the circulation pump of the air conditioner, electricity can be saved by more than 60 percent; and by realizing centralized acquisition and management of the operating datum of a heating system, the air-conditioning unit can be unattended, and a large quantity of human resource is saved.
Description
Technical field
The utility model belongs to the energy-saving equipment field, the energy-saving and frequency-variable control device of particularly a kind of air conditioning pump, blower fan.
Background technology
According to relevant departments climatic data statistical analysis is in recent years learnt, because global climate " warms ", climate change is bigger, this has been caused the great attention of each big city heating refrigeration trade management department, renewal of the equipment and management in more should strengthening producing for northern city heat supply enterprise are to reduce unnecessary energy waste.
We know that the spring and autumn in every year exists the seasonal temperature difference, existence in winter in summer difference warm in nature in the daytime changes.Blower fan in the air-conditioning system, the long-term constant speed running of water pump will cause a large amount of energy wastes and equipment loss.If do not take conservation measures, energy waste and equipment loss just will continue to enlarge.
Pass through to adopt air-conditioning integrated monitoring dispatching patcher for the building air-conditioner system, can control and regulate the operational factor of building air-conditioner system in time, exactly, in satisfying heat supply network under the prerequisite in indoor temperature winter/summer 18 ± 2/26 ℃ ± 2 of each user, reach energy-saving effect to greatest extent, so not only improve the supply capacity of air-conditioning system, and reduce the discharging of pollutant.Make air-conditioning system by season variations in temperature, daytime temperature change the energy-saving and frequency-variable operation, thereby can obtain 15% expansion energy supply power, can eliminate most of family uneven in temperature; By realizing that the temperature Compensation Regulation can save energy more than 13%; By formulating the VFC operating scheme of rational air-conditioning draught fan, circulating pump, can economize on electricity reaches 60%.
The utility model content
The purpose of this utility model is can not exist the seasonal temperature difference, existence in winter in summer poor variation the warm in nature in the daytime with spring and autumn at the blower fan in the existing air-conditioning system, water pump, long-term constant speed running, the deficiency of a large amount of energy wastes and equipment loss will be caused, the energy-saving and frequency-variable control device of a kind of air conditioning pump, blower fan is provided, it is characterized in that the compressor of the energy-saving and frequency-variable control device of described air conditioning pump, blower fan is connected with cooling water heat exchanger and chilled water heat exchanger respectively; Cooling water heat exchanger connects cooling water pump, and cooling water pump connects spray equipment by pipeline, places cooling tower below spray equipment, and the cooling tower bottom connects cooling water heat exchanger by pipeline; Chilled water heat exchanger connects chilled water circulating pump, and chilled water circulating pump joins by the water inlet pipe of pipeline and air-conditioned room, and the water return outlet of air-conditioned room is connected to chilled water heat exchanger by pipeline.
Described spray equipment and cooling tower upper fixed blower fan.
Described blower fan, cooling water pump, chilled water circulating pump and compressor connect frequency converter respectively.
The beneficial effects of the utility model are that air-conditioning system blower fan, cooling water pump, chilled water circulating pump and compressor connect frequency converter respectively, by its operation of Frequency Converter Control, satisfy each user's 18 ± 2 ℃ of indoor temperature winters, summer 26 ± 2 ℃ prerequisite standard, economize on electricity nearly 60%; Each air-conditioning unit and circulating pump control bin have perfect defencive function.The automatic gauging fault, automatic fault protection has overcurrent, over-and under-voltage, overload, short circuit, overheated self-protection etc., can realize the unmanned of air-conditioning unit, save the great amount of manpower resource.
