Detailed description of the invention
It is the free cooled handpiece Water Chilling Units test device implemented according to this utility model as shown in Figure 3, belongs to indirect type and freely cool down test device.Concrete structure is as follows: includes cooling tower, water tank and the free cooling evaporator of free cooled handpiece Water Chilling Units and freely cools down condenser；Cooling tower is connected with water tank, free cooling evaporator and freely cool down condenser and be set up in parallel with water tank；It is characterized in that: at water tank and free cooling evaporator with freely cool down and arrange a chiller unit between condenser, this chiller unit comprises vaporizer and condenser, described vaporizer with freely cool down condenser and connect, described condenser is connected with free cooling evaporator.
Further, temperature point T6 it is set in free cooling evaporator import and freely cools down condenser inlet one temperature point T7 is set.
Further, free cooling evaporator and freely cool down on the pipeline that condenser is in parallel with water tank respectively, at each tank outlet, one three-way control valve is set, set gradually after three-way control valve and be arranged in series water pump and effusion meter (F1, F2), free cooling evaporator and freely cool down condensator outlet and connect water tank and respective three-way control valve respectively；At each effusion meter water outlet side, condenser inlet and the outlet of free cooling evaporator are respectively provided with a temperature point (T1, T3), evaporator with freely cool down condensator outlet and be respectively provided with a temperature point (T2, T4).
Thus, under this structure designs, a discharge (F1 is designed between existing handpiece Water Chilling Units test device and free cooled handpiece Water Chilling Units, F2) consistent with free cooled handpiece Water Chilling Units design water flow, refrigerating capacity is more than the chiller unit of free cooled refrigerating capacity, the water outlet of the condenser of chiller unit and the evaporator series of free cooled handpiece Water Chilling Units, the vaporizer of chiller unit is connected with the condenser of free cooled handpiece Water Chilling Units, increase free cooled handpiece Water Chilling Units vaporizer influent side temperature point T6 and the temperature point T7 of condenser influent side simultaneously；During test run, owing to chiller unit refrigerating capacity is more than free cooled refrigerating capacity, therefore each Relations with Temperature is T6 > T2 > T1 > T5 > T3 > T4 > T7, now, two inflow temperature T6 and T7 of stable free cooled handpiece Water Chilling Units can be obtained by the coordinated signals of three-way control valve and the load of chiller unit, thus obtain the test data of the freest cooled handpiece Water Chilling Units, refrigerating capacity Q=C × F1 × (T6-T2), thermal balance=[F1 × (T6-T2)]/[F2 × (T4-T7)] × 100%.
Compared with prior art, contrast effect is as follows:
It is illustrated in figure 1 existing handpiece Water Chilling Units test device system structure and schematic flow sheet, the condenser of conventional power unit flows to the heat of water tank and vaporizer flows to after the cold of water tank is mutually mixed, and waste heat (compressor horsepower of handpiece Water Chilling Units) is dispelled the heat by cooling tower.Under this flow process, leaving condenser water temperature T2 > condenser inflow temperature T1 > water tank temperature T5 > vaporizer inflow temperature T3 > vaporizer leaving water temperature T4, i.e. water tank temperature is between four temperature, and Water in Water Tank mixes the inflow temperature maintaining two heat exchangers constant respectively with the water outlet of two heat exchangers.Owing to the leaving condenser water of free cooled handpiece Water Chilling Units can heat up because of absorptive condenser heat, vaporizer water outlet can be lowered the temperature to vaporizer because of release heat, and from the angle of heat transfer, Fig. 1 cannot independently realize this function.
It is illustrated in figure 2 direct-type and freely cools down test device system structure and schematic flow sheet, the boiler side distribution heater that the cold water storage cistern side be divided into two by water tank, being connected with condenser is joined refrigeration unit, is connected with vaporizer, now, relatively low cold water storage cistern temperature can be maintained by refrigeration unit, higher boiler temperature can be maintained by electric heater, so can realize vaporizer inflow temperature T3 > vaporizer leaving water temperature T4 > leaving condenser water temperature T2 > condenser inflow temperature T1.If with addition of the refrigerating efficiency of refrigeration unit be 6.0, its power consumption is 1 part, then electric heater need to put into electricity is 6 parts, could realize the steady testing under the method；So, existing handpiece Water Chilling Units test platform will be unable to directly use, and the electric heater (power consumption accounting 85.7%) simultaneously increased extremely expends again electric energy.
Namely, indirect type of the present utility model freely cools down test device and had both taken full advantage of existing handpiece Water Chilling Units test device, only increase a chiller unit, two temperature sensors and supporting water side ducts, it is possible to accurately, reliable obtain the test data of free cooled handpiece Water Chilling Units；Significantly reducing again overall test power consumption, the electric heater capacity for balancing evaporator refrigerating capacity can all save, it is possible to decrease power consumption more than 80% simultaneously.
