Description
Technical field
The utility model relates to a kind of energy saving water cooling handpiece Water Chilling Units, belongs to field of mechanical technique.
Background technology
Existing water cooled chiller, that the refrigerant gas of the HTHP of compressor discharge is entered shell and tube condenser by pipeline, by lowering the temperature with the heat exchange of cooling water, condensation of refrigerant is become liquid, cooling water after heat absorption heats up flows in cooling tower again and photographed in the middle of air by heat, and then flow back to again in shell and tube condenser after the temperature of reduction cooling water, complete a cool cycles.And the cold-producing medium of liquid state again by pipeline flow to choke valve carry out step-down cooling throttling after enter evaporimeter, heat exchange is carried out with the chilled water entering evaporimeter in evaporimeter, compressor is got back to by pipeline again after the cold-producing medium draw heat evaporation of low temperature, complete a kind of refrigeration cycle, and enter the water of evaporimeter because cooled dose of heat siphons away, temperature is reduced to user's serviceability temperature, user is supplied again by delivery port, chilled water after user uses is (because absorbing the heat of user side, this water temperature rises) be re-circulated to evaporimeter and lower the temperature, complete a chilled water circulation.In use procedure, before not reaching the use water temperature of user's requirement, compressor needs continuous service, and namely compressor operating will consume electric energy, and cause the power consumption of user huge, use cost is high.
Utility model content
Utility model object: the purpose of this utility model is to solve above the deficiencies in the prior art, provides a kind of energy saving water cooling handpiece Water Chilling Units.
Technical scheme: energy saving water cooling handpiece Water Chilling Units described in the utility model, its objective is and like this to realize, a kind of energy saving water cooling handpiece Water Chilling Units, comprise refrigeration compressor, shell and tube condenser, choke valve, evaporimeter, described refrigeration compressor, shell and tube condenser, choke valve, evaporimeter connects and composes coolant circuit successively, described shell and tube condenser is provided with condenser water inlet and the leaving condenser water mouth of recirculated water, described evaporimeter is provided with evaporimeter water inlet and evaporimeter delivery port, described condenser water inlet is connected cooling tower with leaving condenser water mouth, described evaporimeter water inlet is connected subscriber equipment with evaporimeter delivery port.
As optimization, be provided with triple valve between described leaving condenser water mouth and cooling tower, the 3rd interface of described triple valve connects the water inlet of evaporimeter, and the delivery port of described evaporimeter connects water inlet and the cooling tower of condenser.
As optimization, the water outlet of described evaporimeter is provided with cooling-water temperature sensor, and cooling-water temperature sensor connects PLC, and described PLC is also provided with environment temperature sensor, and described triple valve is electronic three-way valve, and described PLC connects electronic three-way valve.
Operation principle: this handpiece Water Chilling Units provides the mode of chilled water to be coordinated by two kinds of Combination of Methods for user, the first circulation temperature lowering mode with chiller unit is substantially identical, but be the increase in the function that cooling tower lowers the temperature to chilled water, namely in the freezing temperature situation of environment temperature higher than user's request, adopt the first kind of refrigeration cycle to reduce freezing temperature, it is made to reach user's serviceability temperature, when environment temperature is equal to or less than the freezing temperature of user's request, adopt the second down cycles, namely triple valve is adjusted, the chilled water of user is directly led in cooling tower, it is made to reach the chilled water temperature of user's request by the cooling carrying out heat exchange (environment temperature) in cooling tower with wind, outlet pipe is flow back into again by pipeline, supply client uses.
Beneficial effect: the PLC that the utility model is carried by handpiece Water Chilling Units controls, the built-in sub-acquisition module of PLC carrys out collecting temperature by the cooling-water temperature sensor being placed in outdoor environment temperature sensor and being placed in evaporimeter water outlet, through the internal arithmetic of PLC analyze and judge to use first or the second way lower the temperature, and outputed signal by built-in sub-output module, drive triple valve select by valve after water (flow) direction (environment temperature is higher than user's request water temperature.Current direction evaporimeter, if environment temperature is equal to or less than user's request water temperature, then current direction cooling tower).
When excessive season and cooling needs in winter, particularly industry, commercial cooling needs throughout the year, the load of first kind of way can be reduced, reduce the time of compressor operating, and then reduce power consumption, for user is cost-saving, the second way only needs for the blower fan of cooling tower is can run for a small amount of electricity, compare the operation power consumption of compressor, the power consumption of blower fan only has the 5-8% of compressor, so energy-saving effect clearly.
Illustrate:
1. when using excessive season, the environment temperature on daytime is higher, the first kind of refrigeration cycle can be used, when entering night environment temperature lower (being equal to or less than user's request freezing temperature), the second way can be adopted to provide chilled water, thus cut off the first kind of refrigeration cycle, the refrigeration compressor that now power consumption is larger stopped work, has namely saved electric energy, serves energy-conservation effect, through measuring and calculating, excessive season uses the electric energy can saving 25-30%.
2. when using in the winter time, the environment temperature of whole day is all very low, and the second down cycles now can be adopted for a long time to meet the demand of user, and now compare the electric energy that common cooling-water machine can save more than 90%, energy-saving effect is more obvious.
