Description
Technical field:
The utility model relates to refrigeration plant, especially belongs to fall an act formula cooling-water machine refrigeration control device.
Background technology
Traditional chilled water machine control device, the most of plate switching heat-exchanger that adopts of evaporimeter, its refrigeration water system is a closed, both evaporimeter was to be immersed in the cold water storage cistern, when leaving water temperature was low, evaporimeter easily produced bursting by freezing, simultaneously when leaving water temperature is lower than 2 ℃, evaporator surface easily freezes, and has reduced refrigerating efficiency widely.So produce less than 2 ℃ low-temperature cold water difficult.
Summary of the invention
The purpose of this utility model provides a kind of act formula cooling-water machine refrigeration control device that falls, and makes to guarantee that fully evaporator surface does not freeze, refrigeration is fast, reliability is high and refrigerating efficiency is high, and can make low-temperature cold water.
Technical solution adopted in the utility model is: it is made up of refrigeration system, refrigeration water system and condensation water system, it is characterized in that: described refrigeration system by the exhaust outlet of compressor successively with condenser, device for drying and filtering, magnetic valve, expansion valve, knockout, stainless steel evaporimeter, constant pressure valve, gas-liquid separator, return-air filter be connected with air entry form; Described refrigeration water system by go out water pump successively with cold water storage cistern, through hole, reservoir, immersible pump, spread water tank with spread the water hole link to each other the institute form.
The beneficial effects of the utility model are: 1, because the evaporimeter that the utility model adopts is a refrigerant flow path flat, that have blow-up, have feed tube and the escape pipe more than 2 more than 2, heat exchange area is big, be fit to the more cold-producing medium of flowing through, so adopt this evaporimeter can reach the purpose that improves the refrigeration system heat exchanger effectiveness; 2, refrigeration water system of the present utility model is open, and the stainless steel evaporimeter is not installed in the cold water storage cistern, and is mounted in the top of cold water storage cistern.Even therefore the temperature of evaporimeter is moved about-5 ℃, can guarantee that also evaporimeter bursting by freezing danger can not take place, because temperature is low, so refrigerating speed is fast, this simultaneously owing to adopt open installation, the surface of evaporimeter is also cleaned easily, has made things convenient for maintenance; 3, the excessive water circulation technology is adopted in water supply of the present utility model.The water-circulating pump that is installed in the reservoir constantly sprays excessive water on two outer surfaces of evaporimeter owing to be to use excessive water, so make it with evaporimeter in cold-producing medium can carry out heat exchange fully; Improved refrigerating efficiency, the water that turns cold flows directly in the cold water storage cistern of its below.Because water constantly sprays, the device surface that so just avoids evaporating freezes.Also be to have improved refrigerating efficiency; 4, refrigeration system of the present utility model is installed a constant pressure valve on the muffler of evaporimeter, stablized the evaporating pressure of cold-producing medium, has also just stablized evaporating temperature.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Be illustrated in figure 1 as the utility model schematic diagram, it is made up of refrigeration system, refrigeration water system and condensation water system, it is characterized in that: described refrigeration system by the exhaust outlet 121 of compressor 12 be connected with condenser 15, device for drying and filtering 14, magnetic valve 13, expansion valve 5, knockout 6, stainless steel evaporimeter 7, constant pressure valve 9, gas-liquid separator 11, return-air filter 10 and air entry 122 successively form; Described refrigeration water system by go out water pump 1 successively with cold water storage cistern 3, through hole 25, reservoir 24, immersible pump 23, spread water tank 8 with spread water hole 81 link to each other the institute form.
Cold water temperature controller 2, high level switch 4 are housed on the cold water storage cistern 3 described in the utility model.
Condensation water system described in the utility model by the cooling tower 19 that floating ball valve of rehydration 18 is housed by flow switch 17, water pump 16 be connected with condenser 15 institute form.
Stainless steel evaporimeter 7 described in the utility model is refrigerant flow path flat, that have blow-up, and has feed tube and 2 above escape pipes more than 2.
Operation principle of the present utility model is: in refrigeration system, the compressor 12 of operation, the gas refrigerant of low-temp low-pressure is compressed into the gas refrigerant of HTHP, flow in the condenser 15 through exhaust outlet 121, in this process, after carrying out heat exchange with cold water, the liquid of warm high pressure in converting to, after drying filter 14, magnetic valve 13 flow to expansion valve 5 then, the liquid that cold-producing medium becomes low-temp low-pressure enters knockout 6, entered in each stainless steel evaporimeter 7 by uniform distribution, and in this vaporization heat absorption; The refrigeration water system is also worked simultaneously, water in the reservoir 24 is extracted out to flow to by immersible pump 23 and is spread in the water tank 8, and from spread water hole 81, constantly be sprayed onto equably on two outer surfaces of stainless steel double evaporators 7, being the film woman's persona flows down, its simultaneously with evaporimeter 7 inner chambers in the cold-producing medium of vaporizing carry out heat exchange and become cold water and flow down, fall into cold water storage cistern 3; So constantly circulation, the water temperature in the cold water storage cistern 3 reduces gradually, and when reaching the cold water temperature value of regulation, cold water temperature controller 2 sends signal, goes out water pump 1 and starts, and cold water is pumped be transported to the place that needs; Water inlet 20 flows into warm water to reservoir 24 at this moment, and the warm water amount of inflow is controlled by liquid-level switch 22, and repeats above-mentioned refrigeration water supply circulation again.And in the stainless steel evaporimeter 7, the refrigerant gas of the low-temp low-pressure after the vaporization heat absorption enters from the air entry 122 of compressor 12 through constant pressure valve 9, gas-liquid separator 11, is compressed again, finishes the circulation of a refrigeration system.In two above-mentioned system works, the condensation water system is also in synchronous working, water pump 16 squeeze into by cooling tower 19 chilled water in the condenser 15 with finish heat exchange from the gas refrigerant of the HTHP of compressor 12 after be heated, returning cooling tower 19 through flow switch 17 cools off again, so constantly circulation, when quantity of circulating water is not enough, introduce warm water again from the external world to cooling tower 19, the warm water amount of introducing is controlled by floating ball valve of rehydration 18.
