Background technology
Along with the fast development of society and the raising of people's living standard, the ratio of the energy consumption of air-conditioning system in entire society life is increasing, sometimes even become the major part of enterprise's production cost.Energy consumption cost is huge, and energy-saving potential is also very large simultaneously.Therefore, taking measures to reduce energy consumption and will bring huge economic benefit to applying unit, also is the active response to the call of national energy-saving reduction of discharging.
At present, the connected mode of dual system water-cooling screw rod unit connects by an evaporimeter between two systems as shown in Figure 2.Dual system water-cooling screw rod unit water side and fluorine side do not realize countercurrent flow fully, and the logarithm heat transfer temperature difference is less; Chilled water and cooling water system generally adopt mode in parallel, and evaporating temperature and the condensation temperature of two systems are just the same, and the overall heat exchange effect is not good enough, therefore efficiency is not high, the space has greatly improved.
Summary of the invention
The utility model provides a kind of double-pressing machine dual system water-cooling screw rod unit water fluorine string contracurrent system, has solved the problem that water side and fluorine side have realized complete adverse current, has increased the problem of logarithm heat transfer temperature difference, and series design is carried out in the water system aspect simultaneously.
The utility model is realized with following technical scheme: a kind of double-pressing machine dual system water-cooling screw rod unit water fluorine string contracurrent system comprises the first fluorine side Air Conditioning System that is made of a system compresses machine, a system evaporator, system's throttling arrangement and system condensing device series connection; The the first fluorine side Air Conditioning System that is consisted of by two system compressor, two system evaporimeter, two system throttling arrangement and the series connection of two system condenser; It is characterized in that: a system evaporator and two system evaporimeter all adopt the single process design, and the delivery port of a system evaporator connects the water inlet of two system evaporimeter; The delivery port of one system condensing device connects the water inlet of two system condenser.
The beneficial effects of the utility model are: 1, water side and the complete adverse current of fluorine side, increased heat transfer temperature difference, and strengthened heat transfer effect.
2, a system evaporator water outlet enters the two system evaporimeter again and continues to cool to and require temperature, like this, just improved the evaporating temperature of a system, a simultaneously system condensing device water outlet enters the two system condenser again and continues heat radiation, when guaranteeing the complete machine heat transfer effect, reduced the condensation temperature of a system.
3, from whole structure, adopt the mode of string adverse current, the unit refrigerating capacity further improves, and consumed power further reduces, and reaches the purpose of efficient energy-saving.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is this practical dual system water-cooling screw rod unit water fluorine string contracurrent system structural representation;
Fig. 2 is existing dual system water-cooling screw rod unit water fluorine flow system structural representation.
Among the figure: 1, a system condensing device, 2, the two system condenser, 3, one system's throttling arrangement, 4, one system compresses machine, 5, the two system compressor, 6, one system evaporator, 7, the two system evaporimeter, 8, the two system throttling arrangement.
The specific embodiment
As shown in Figure 1, a kind of double-pressing machine dual system water-cooling screw rod unit water fluorine string contracurrent system comprises the first fluorine side Air Conditioning System that is made of a system compresses machine 4, a system evaporator 6, system's throttling arrangement 3 and a system condensing device 1 series connection; The the first fluorine side Air Conditioning System that is consisted of by two system compressor 5, two system evaporimeter 7, two system throttling arrangement 8 and 2 series connection of two system condenser.Said elements forms respectively independently air-conditioning system of two fluorine sides.
Make water side and fluorine side realize complete adverse current by above-mentioned annexation, increased the logarithm heat transfer temperature difference; Wherein, a system evaporator 6 and two system evaporimeter 7 all adopt the single process design, and the delivery port of a system evaporator 6 connects the water inlet of two system evaporimeter 7; One system condensing device 1 and two system condenser 2 all adopt the single process design, and the delivery port of a system condensing device connects the water inlet of two system condenser.The delivery port water temperature of one system condensing device 1 is 35 ℃, and the water inlet water temperature of two system condenser 2 is 30 ℃.The freezing delivery port water temperature of one system evaporator 6 is 7 ℃, and the freezing water inlet water temperature of two system evaporimeter 7 is 12 ℃.It is for to reduce flow velocity that one system evaporator 6 and two system evaporimeter 7 all adopt the single process design, reduces water resistance, with water side countercurrent flow, increases the logarithm heat transfer temperature difference; The evaporimeter internal baffle must be checked distribution again, avoids water resistance larger.For example: the unit of former 600kW single system, the quantity of evaporimeter internal baffle are designed to 13, and the breach ratio is 35%.Now design evaporimeter internal baffle quantity and be adjusted into 9, the breach ratio is adjusted into 40%.It is in order to reduce water flow velocity, the control water resistance that one system condensing device 1 and two system condenser 2 all adopt the single process design.The form of series connection is adopted in the water route of two air-conditionings, i.e. the evaporimeter that the evaporimeter water outlet of a system enters two system continues to cool to desired temperature.Or since a system evaporator leaving water temperature just reach the temperature that requires half be certain temperature value of centre, so just improved the evaporating temperature of a system; Simultaneously, the water outlet of a system condensing device enters into the two system condenser and continues heat radiation, when guaranteeing the complete machine heat transfer effect, has reduced the condensation temperature of a system.Or since a system condensing device leaving water temperature also just reach the temperature that requires half be certain temperature value of centre, so just reduced the condensation temperature of a system.Like this, from whole structure, the unit refrigerating capacity further improves, and consumed power further reduces, and makes efficiency improve about 8%.
