Ambient cold energy in cold season is fully used for cooling ice water, so that operating time of the ice water machine is shortened, and energy saving is realized.
Description
Technical field
The utility model relates to the industrial energy saving field, refers in particular to frozen water machine, cooling-water machine etc. are realized energy-conservation Apparatus and system.
Background technology
In the industry and commerce activity, often have the demand that frozen water uses.Such as in food, medicine, rubber, plastic processing machine tool mold cools down, the product surface of producing through overcooled mould is smooth, reduces alligatoring and internal stress, makes product shrink-proof indeformable.Usually also need cooling water to cool off for numerical controlled machinery, grinding machine, machining center etc.For usually realizing with ice making wetting system systems such as frozen water machine, cooling-water machines in the demanding situation of cooling water temperature.The principle of frozen water machine also is the ice water circulation system by heat exchange, will be fed to frozen water through overcooled water and use the zone, and the frozen water with used high-temperature is back to again cooling in the frozen water machine interchanger again.When the frozen water mechanism cold, it need start compressor and refrigeration system work thereof, and power consumption is large.Especially in the very low situation of ambient temperature in winter, the frozen water machine also need freeze, and fails to take full advantage of the cold energy of external environment and realizes energy-conservation.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of when ambient temperature is lower than the temperature of indoor running water a kind of cooling water-cooled reclaim the frozen water exchange system, do not utilize frozen water machine cooling frozen water in cold season, only utilize the environment cold energy to carry out the frozen water cooling, realize energy-conservation purpose.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is that the cooling water-cooled reclaims the frozen water exchange system, it comprises the frozen water machine, and described frozen water machine uses regional connectivity by frozen water feed pipe and frozen water, and described frozen water suitable application region is communicated with described frozen water machine by CHR; Characterized by further comprising a heat exchanger, the input of the hot media channel of described heat exchanger and output are communicated with described CHR by connecting pipe respectively, on the input connecting pipe and output connecting pipe of described hot media channel, and described CHR between described hot media channel input and output be separately installed with valve; The output of the cold medium channel of described heat exchanger is communicated with cooling tower respectively with input.
Cold medium pipeline at described heat exchanger is equipped with water circulating pump with the circulating line that described cooling tower is communicated with.
On the described cooling tower cooling fan is installed.
Input and output one side at the hot media channel of described heat exchanger are separately installed with temperature sensor.
Output at the hot media channel of described heat exchanger is equipped with flowmeter, a calorimeter respectively with the input of described hot media channel be connected with output temperature sensor be connected flowmeter and be connected.
The utility model took full advantage of in cold season, when outdoor environment wet-bulb temperature is lower than 8 degrees centigrade of situations, the frozen water that the water that utilizes outdoor lower temperature uses as cold side medium and hot side carries out heat exchange, thereby reduces the frozen water serviceability temperature and make it reach the setting value of expection.In cold season, can allow the frozen water machine be in standby off position or intermitten by the utility model always, the huge energy consumption that has caused when having reduced frozen water machine compressor operating has realized energy-conservation purpose.
Description of drawings
Fig. 1 system architecture schematic block diagram of the present utility model.
The specific embodiment
For technique scheme, now lift a preferred embodiment and be specifically described in conjunction with graphic.Referring to Fig. 1, frozen water exchange system of the present utility model comprises that frozen water machine 1, frozen water feed pipe 2, frozen water use zone 3, CHR 4, heat exchanger 5, cooling tower 6, calorimeter 7, wherein.
Frozen water machine 1, adopt in the present embodiment water-cooled frozen water machine, it comprises the waterpipe that is cooled, frozen water uses zone 3 to be communicated with by the outlet of the waterpipe that is cooled in frozen water feed pipe 2 and the frozen water machine 1, frozen water uses zone 3 to be communicated with frozen water machine 1 by CHR 4, forms an ice water circulation loop.Near on the frozen water machine one end pipeline water circulating pump 11 and flowmeter 12 are installed successively at CHR 4, provide mobilization dynamic by water circulating pump for the ice water circulation loop, by the frozen water amount in the flowmeter 12 statistics inflow frozen water machines; At the frozen water feed pipe water supply pump is installed, provides the frozen water mobilization dynamic by water supply pump for frozen water uses the zone.
The operation principle of frozen water exchange system of the present utility model is as follows.
When outdoor environment wet-bulb temperature is lower than below 8 degrees centigrade, move this system: close bypass valve 41, open valve (53,54), use regional used high temperature frozen water to enter in the waterpipe that is cooled that flows into after heat exchanger 5 carries out heat exchange with cooling water in the outdoor environment inflow heat exchanger 5 in the frozen water machine through frozen water, when temperature sensor 52 detection water temperatures in heat exchanger place are lower than setting value, frozen water machine standby this moment, the frozen water that carries out heat exchange through heat exchanger 5 flows directly into frozen water use zone use through frozen water machine and frozen water feed pipe; When temperature sensor 52 detection water temperatures were higher than setting value, this moment, the frozen water machine carried out work, used the zone that frozen water is provided to frozen water.Usually, during operational system, the frozen water that cooled off through heat exchanger 5 nearly all can be lower than setting value when being lower than below 8 degrees centigrade when outdoor environment wet-bulb temperature, and therefore, the frozen water machine starts hardly.
When the outdoor environment wet-bulb temperature such as spring, summer, autumn, early winter were higher than 8 degrees centigrade, then valve-off (53,54) was opened valve 41, started the work of frozen water machine, carried out forced refrigeration.
Frozen water exchange system of the present utility model, the environment cold energy that takes full advantage of cold season carry out the frozen water cooling, have reduced frozen water machine running time, have reduced the energy consumption that the operation of frozen water machine brings, and have realized energy-conservationly, and make amount of energy saving.
