Furthermore, the adverse current high water temperature heat exchanger of the utility model develops wide prospect for the wide application for the high-temperature cold accumulation, and the use of the natural cold source such as well water, lake water, seawater, etc.
Description
Technical field
The utility model relates to refrigeration plant, especially a kind of heat-exchange device of refrigeration system.
Background technology
Along with the high speed development of China's construction, increasing air-conditioning equipment is used to improve people's work and living environment.Yet being extensive use of of air-conditioning equipment caused the huge consumption of the energy again, and people look forward to designing and produce energy-efficient product, to adapt to the sustainable development of China's economic construction.The flow direction of the end-equipment of existing central air conditioner system---surface cooler for fan coil chilled water all be take to advance under the chilled water (intake 7 ℃, water outlet 12 ℃), on the working forms that goes out, the flow direction of water and wind direction vertical, promptly adopt the distributary heat exchange, as shown in Figure 1.This for many years structure is being dominated the design philosophy of industry, and people habitually produce, use this constructed products, no longer considers to adopt new structural design to improve the combination property of heat-exchanger rig.But, to pay attention to cutting down the consumption of energy, protecting environment, carry out in the spring tide of sustainable development in the current whole world, traditional heat-exchanger rig is the development of incompatibility form.The fan coil of traditional central air conditioner system is because structure is limited to, and the reasonable value of its leaving air temp must be higher than the temperature of chilled water water outlet, makes that the heat exchange efficiency of refrigeration system is lower, thereby causes energy consumption higher, is difficult to have breakthrough.Particularly along with the raising (as 12 ℃ of water inlets, 17 ℃ of water outlets) of chilled water temperature, traditional heat-exchanger rig heat exchange efficiency is lower, even is difficult to satisfy requirements of one's work.
The utility model content
The purpose of this utility model is lower, the energy consumption technical problems of high of heat-exchange device heat exchange efficiency that will solve existing central refrigerating system, proposes the high water temperature heat exchanger of a kind of energy-efficient adverse current.
The technical solution that the utility model proposes is to adopt the high water temperature heat exchanger of a kind of adverse current, it comprises heat exchange fin cohort that multi-disc is spaced apart, be set in heat exchange pipeline bundle in the described fin cohort, be located at chilled water import and chilled water outlet described fin cohort two ends and that be communicated with described heat exchange pipeline bundle two ends respectively, also comprises being located at away from described chilled water import, near the blower fan of described chilled water outlet.
Wherein, described chilled water import can be located at the top of described fin cohort, and described chilled water outlet also can be located at the top of described fin cohort.
Described chilled water import can be located at the top of described fin cohort, and described chilled water outlet is located at the bottom of described fin cohort.
Described chilled water import can be located at the bottom of described fin cohort, and described chilled water outlet is located at the top of described fin cohort.
The utility model employing air supply direction and chilled water flow are to the version of countercurrent flow, improved heat exchange efficiency widely, under the situation that guarantees indoor temperature constant (relative humidity increases to some extent), make refrigeration machine chilled water outlet temperature improve 5 ℃-6 ℃, the corresponding efficient 15%-20% that improves refrigeration machine.Be used widely as this heat exchanger, electric power can be saved in 10,000,000,000 kwh every year in the whole nation.In addition, the high water temperature heat exchanger of the adverse current that the utility model proposes has also been opened up wide prospect for the utilization of the extensive use of high-temperature and cold-storage, natural cold source such as well water, lake water, seawater etc., thereby obtains very huge economic benefit and social benefit.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, wherein:
Fig. 1 is the structural representation of existing heat exchanger;
Fig. 2 is the structural representation of the utility model preferred embodiment.
The specific embodiment
Fig. 1 shows the basic structure of existing a kind of fan coil, and wherein, blower fan 5 is located at an end of heat exchange fin cohort 1, and the import 3 of simultaneously close chilled water and outlet 4, chilled water enters from the bottom, flows out from top, and air supply direction is vertical with the turnover flow direction of chilled water, i.e. distributary heat exchange.The reasonable value of the leaving air temp of this structure must be higher than the temperature of chilled water water outlet, makes that the heat exchange efficiency of this product is lower, thereby causes energy consumption higher, is difficult to have breakthrough.
Fig. 2 shows the structure of the utility model preferred embodiment, the high water temperature fan coil of described a kind of adverse current, it comprises heat exchange fin cohort 1 that multi-disc is spaced apart, be set in heat exchange pipeline bundle 2 in the described fin cohort 1, be located at chilled water import 3 and chilled water outlet 4 described fin cohort 1 two ends and that be communicated with described heat exchange pipeline bundle 2 two ends respectively, the top of described fin cohort 1 is located in described chilled water import 3, and described chilled water outlet 4 also is located at the top of described fin cohort 1.Also comprise the blower fan of being located at away from described chilled water import 3, close described chilled water outlet 45.The flow direction of chilled water is that the right side is entered a left side and gone out, and flowing to of the air supply direction of blower fan and chilled water is reverse, i.e. countercurrent flow.Calculate and actual test shows by theory, the logarithmic mean temperature difference (LMTD) of the high water temperature fan coil of adverse current is greater than the logarithmic mean temperature difference (LMTD) of conventional fan coil pipe, and along with the raising (being that heat transfer temperature difference descends) of chilled water temperature, above-mentioned effect is more obvious.For example, when environment temperature is 24 ℃, if chilled water temperature is brought up to uniform temperature (12 ℃ of water inlets, 17 ℃ of water outlets), the temperature difference of the high water temperature fan coil of adverse current improves more than 20% than the temperature difference of conventional fan coil pipe under the similarity condition, and the leaving air temp of the high water temperature fan coil of adverse current can also be lower than the leaving water temperature of chilled water, obviously, when the fan coil of this structure was used for high water temperature operating mode, heat exchange efficiency was much improved, and energy-saving effect is just obvious especially.In order to guarantee original heat exchange effect down at higher chilled water temperature (as 12 ℃ of water inlets, 17 ℃ of water outlets), can just only need suitably increase the heat exchange area of surface cooler.
The position of import of corresponding change chilled water and chilled water outlet can obtain other embodiment of the utility model.As the top of fin cohort 1 as described in described chilled water import 3 is located at, described chilled water outlet 4 is located at the bottom of described fin cohort 1; Perhaps described chilled water import 3 is located at the bottom of described fin cohort 1, chilled water outlet 4 is located at the top of described fin cohort 1.
