Abstract
The utility model discloses a large temperature difference water cold accumulation device which comprises a refrigerating main machine, a cold accumulation water tank, a water inlet pipe and a water outlet pipe. The water inlet pipe and the water outlet pipe are connected with the cold accumulation water tank. The large temperature difference water cold accumulation device further comprises a bypass part connected between the water inlet pipe and the water outlet pipe on the cold accumulation water tank. Control valves are respectively arranged on the water inlet pipe and the water outlet pipe on one side of the cold accumulation water tank, and a flow control device is arranged on the bypass part. The flow control device comprises an electric adjusting valve and a constant flow valve which are in parallel connection. The large temperature difference water cold accumulation device can accumulate cold on the situation of large temperature difference and prevents original layers of the cold accumulation water tank from being destroyed.
Description
Technical field
The utility model relates to refrigeration plant, relates in particular to a kind of large temperature difference water cold accumulation device.
Background technology
Cold-storage device is the energy saver that applies to air-conditioning system, and it utilizes the use cost that peak load has reduced air-conditioning effectively of filling out of electricity price.In existing water cold accumulation device, main frame is not supported the operation of the large temperature difference, or when the operating mode operation of the large temperature difference (for example △ T＞8 ℃) decrease in efficiency.For addressing this problem, common way is that two main frame series connection are used, to reduce the turnover temperature difference of main frame.But, even adopt the two-stage main frame to carry out large temperature difference operating mode operation, particularly the water at low temperature in water storage pool does not discharge and carries out cold-storage when operation, main frame has a process that progressively loads, and the temperature difference is enlarged to setting value gradually needs 5-10 minute, during this period, high-temperature water has directly entered in the low temperature water layer of basin bottom, produce stronger convection current, the inclined-plane layer is produced destroy, affected the stability of water storage pool.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in prior art, proposes the large temperature difference water cold accumulation device of a kind of improvement.
A kind of large temperature difference water cold accumulation device that the utility model proposes, comprise refrigeration host computer, water storage pool and the water inlet pipe that is connected with water storage pool and outlet pipe, comprise that also one is connected to the bypass between the water storage pool inlet tube and outlet tube, described bypass is provided with volume control device.
Described volume control device comprises electric control valve parallel with one another and constant flow rate valve.Described electric control valve is connected with the temperature sensor that is arranged on the main frame influent side and by the motor-driven valve driver control.
Compared with prior art, the utility model utilizes the bypass that arranges between the water storage pool water inlet pipe and water outlet pipe, and water storage pool outlet pipe and bypass are converged, and has effectively reduced the inflow temperature of main frame, reduced the Inlet and outlet water temperature difference of main frame, made the operational efficiency of main frame obtain certain raising.In addition, kept the layering of water water storage pool temperature stable.
Description of drawings
Fig. 1 is the schematic diagram of prior art;
Fig. 2 is schematic diagram of the present utility model;
Fig. 3 is the schematic diagram of the utility model intermediateness;
Fig. 4 is the schematic diagram of the utility model stable state.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 comprises water inlet pipe 104 and the outlet pipe 105 of first order main frame 101, second level main frame 102, water storage pool 103 and water storage pool for adopting the water cold accumulation device of two main frame series connection, and water inlet pipe and water outlet pipe is respectively equipped with control valve 107 and 108 in water storage pool one side.The leaving water temperature of second level main frame is 4 degree cold water.When main frame just started, leaving water temperature did not reach 4 degree, and directly send in water storage pool 103 this moment, can destroy the stability of water storage pool.And main frame adopts two pole compression, and cost is high.
Fig. 2 is the large temperature difference water cold accumulation device that the utility model proposes, comprise refrigeration host computer 1, water storage pool 3 and the water inlet pipe 4 that is connected with water storage pool and outlet pipe 5, comprise that also one is connected to the bypass 6 between the water storage pool water inlet pipe and water outlet pipe, water inlet pipe and water outlet pipe is respectively equipped with control valve 7 and 8 in water storage pool one side.Bypass 6 is provided with flow regulator.This volume control device comprises electric control valve parallel with one another 9 and constant flow rate valve 10.Electric control valve 9 is connected with the temperature sensor that is arranged on the main frame influent side and is controlled by motor-driven valve driver 11.
During work, minute following three kinds of states:
1, opening, process of cool begins, and starting mode of pump, refrigeration host computer 1 do not start, at this moment, and electric control valve 9 standard-sized sheets, constant flow rate valve 10 is opened.Refrigeration host computer Inlet and outlet water temperature is 15 degree Celsius, as shown in Figure 2.
2, intermediateness, process of cool, water pump is opened, and refrigeration host computer 1 is opened, and outlet pipe 5 parts are opened, and electric control valve 9 parts are opened, and constant flow rate valve 10 is opened.Main frame Inlet and outlet water temperature progressively reduces, as shown in Figure 3.
3, stable state, water pump is opened, and refrigeration host computer 1 is opened, and electric control valve 9 and constant flow rate valve 10 are closed.Main frame Inlet and outlet water temperature is 9 degree Celsius, and leaving water temperature is four degrees celsius, as shown in Figure 4.
The utility model adopts bypass 6, the mode that chilled water in water storage pool outlet pipe 5 and high-temperature water are converged, the temperature that enters refrigeration host computer when cold-storage is started progressively reduces, not only improved the operating efficiency of refrigeration host computer, and guaranteed the stability of water storage pool, in addition, make refrigeration host computer adopt one-level mode of operation, the cost of the operation and maintenance of having demoted.
The utility model has solved the problem of large temperature difference water cold-storage operation effectively, makes the large temperature difference operating condition of separate unit main frame support, and simple in structure, cost is low, good stability.
