Technical Field

The utility model belongs to the energy supply system, concretely relates to regional energy station of energy supply is realized to usable central heating pipeline.

Background

Conventional building air conditioning system sets up the refrigeration station to an energy consumption unit for building, prepares air conditioner refrigerated water, rethread circulating water pipe system provides the refrigerated water to the terminal system of air conditioner of this energy consumption unit for building, to a building crowd, has included a plurality of energy consumption units for building, needs each energy consumption unit for building self configuration refrigeration station promptly to satisfy the air conditioner demand of each energy consumption unit for building. And regional cooling is to set up concentrated energy source station to a large area scope's building crowd, prepares air conditioner refrigerated water, and rethread circulating water pipe system provides the refrigerated water to each building energy consumption unit air conditioner end system. The peak value of the air conditioning load of each building energy consumption unit generally does not occur at the same time.

Wherein, contained a plurality of monomer buildings in the building crowd, a monomer building probably is a building energy unit, also probably because the function is different, divides into a plurality of building energy units, and when several monomer buildings's function is the same and adjacent, also probably is a building energy unit, in a word, has contained a plurality of building energy units in certain regional building crowd.

According to technical measures of civil architectural engineering design across the country-heating ventilation air conditioning power (2009), (1) regarding cold source equipment selection of conventional air conditioning systems, clause 6.1.5: when the installed capacity of the water chilling unit is determined, the probability that the peak load of air conditioners in rooms with different orientations and different purposes simultaneously appears and the difference of the working conditions of the air conditioners of various buildings are fully considered, and the air conditioner load is multiplied by a correction coefficient smaller than 1, wherein the correction coefficient can be 0.70-0.90 generally; the lower limit is preferably taken when the building is large in scale, and the upper limit is preferably taken when the building is small in scale; (2) regarding zone cooling, item 6.3.4: when the capacity is calculated, the simultaneous use coefficient and the non-guarantee rate are determined according to the function and the cold use characteristic of each subarea. In general, the coefficient of co-usage is preferably 0.5 to 0.8.

It can be known that the cold source equipment model selection correction coefficient of the conventional air conditioning system can be generally 0.70-0.90, the cold source equipment model selection correction coefficient (the use coefficient) of the regional cold supply can be 0.5-0.8, and in general, the installed capacity of the cold source for the regional cold supply is smaller than the total installed capacity of energy consumption units of each building when cold sources are dispersedly arranged, so that the initial investment of a water chilling unit and supporting facilities thereof is reduced, the water chilling unit can be kept to work under a high load rate, and high energy efficiency is kept.

For the scheme selection of building group cooling, theoretically, compared with the method that water chilling units are dispersedly arranged in each building energy consumption unit, the regional cooling mode has obvious investment and operation advantages, but still has more problems in practice, and mainly comprises the following steps: (1) the energy-saving system has the advantages that the energy-saving system is characterized in that the energy-saving energy station is used for conveying air-conditioning chilled water to each energy-consuming building unit, and a water supply and return pipe for conveying and distributing the air-conditioning chilled water needs to be newly built, so that the system investment is increased; (2) the building groups with a large area range are often not built and put into use at the same time, and the corresponding scale can be achieved after years of development, but the corresponding construction scale and equipment investment need to be planned at the initial stage of the regional cooling mode, so that the operation economy at the initial stage of regional construction is poor, and the investment recovery is not facilitated.
