Abstract
The utility model relates to an energy-conserving heat transfer system in winter based on outdoor water storage tank, including PCW unit, water tank, heat exchanger, freezer and water storage tank, the cooling water return water of PCW unit connects the water tank, and the water tank is through the one-level pipeline and the freezer of a three-way valve connection heat exchanger, and heat exchanger and freezer are intake through the cooling water of No. two three-way valve connection PCW units, and the water storage tank is connected to the second grade pipeline return water of heat exchanger, and the water storage tank is intake through the dipolar pipeline that the heat exchanger was connected to the water pump, and the water storage tank is located outdoors. The utility model has the advantages that: when the temperature is lower in winter, the first three-way valve and the second three-way valve are both communicated with the heat exchanger, and when the temperature is higher, the first three-way valve and the second three-way valve are both communicated with the freezer. When the heat exchanger is communicated, the cooling water return water and the low-temperature water in the water storage tank finish heat exchange in the heat exchanger, so that the temperature of the cooling water is reduced. Thereby effectively utilizing the low-temperature water in the outdoor water storage tank in winter to cool the cooling water.
Description
Technical Field
The utility model relates to a, especially, relate to an energy-conserving heat transfer system in winter based on outdoor water storage tank.
Background
Process cooling water systems (PCW), also known as process cooling water systems. The air conditioning system is mainly used for cooling process equipment, namely simply the air conditioning system of the process equipment. The PCW system includes two relatively independent systems, i.e., chilled water supplied from a refrigerator and cooling water, and the chilled water exchanges heat with the cooling water to lower the temperature of the equipment by lowering the temperature of the cooling water. Water is pumped from production equipment to the plate heat exchanger through the water pump, the water temperature of the PCW is guaranteed by controlling the amount of chilled water, the water passes through the filter and is sent to the production line equipment, and then the water returns to the water pump. Forming a PCW closed cycle. The chilled water side is returned directly to the freezer. The PCW water tank is used as a water replenishing system of the PCW system.
In northern areas of China, the outdoor temperature is low, and a large amount of low-temperature water is stored in the outdoor water storage tank. In the prior art, the natural cold source cannot be effectively utilized.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide an energy-conserving heat transfer system in winter based on outdoor water storage tank, effectively utilize the low temperature water in the outdoor water storage tank in winter.
The utility model discloses a realize through following technical scheme:
the utility model provides an energy-conserving heat transfer system in winter based on outdoor water storage tank, including the PCW unit, the water tank, a heat exchanger, freezer and water storage tank, the water tank is connected to the cooling water return water of PCW unit, the water tank is through one-level pipeline and the freezer of a three-way valve connection heat exchanger, heat exchanger and freezer are intake through the cooling water of No. two three-way valve connection PCW units, the water storage tank is connected to the second grade pipeline return water of heat exchanger, the water storage tank is intake through the dipolar pipeline that the water pump connects the heat exchanger, the water storage tank is located outdoors.
The utility model has the advantages that: when the temperature is lower in winter, the first three-way valve and the second three-way valve are both communicated with the heat exchanger, and when the temperature is higher, the first three-way valve and the second three-way valve are both communicated with the freezer. When the heat exchanger is communicated, the cooling water return water and the low-temperature water in the water storage tank finish heat exchange in the heat exchanger, so that the temperature of the cooling water is reduced. Thereby effectively utilizing the low-temperature water in the outdoor water storage tank in winter to cool the cooling water.
Drawings
Fig. 1 shows a schematic front view structure diagram of an embodiment of the present invention.
In the figure: the system comprises a PCW unit, a water tank, a heat exchanger, a freezer, a water storage tank, a cooling water return water tank, a three-way valve I, a three-way valve II, a cooling water inlet water tank, a water storage tank and a water storage tank, wherein the PCW unit, the water storage tank.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model relates to an energy-conserving heat transfer system in winter based on outdoor water storage tank, including PCW unit 1, water tank 2, heat exchanger 3, freezer 4 and water storage tank 5, the cooling water return water 6 of PCW unit connects the water tank, the water tank is through one-level pipeline and the freezer that three-way valve 7 connects the heat exchanger, the cooling water 9 of intaking that heat exchanger and freezer pass through No. two three-way valve 8 connection PCW units, the water storage tank is connected to the second grade pipeline return water of heat exchanger, the water storage tank is intake through the dipolar pipeline that water pump 10 connects the heat exchanger, the water storage tank is located outdoors.
In this embodiment, when temperature was lower winter, No. one three-way valve and No. two three-way valves all communicate the heat exchanger, and when temperature was higher, No. one three-way valve and No. two three-way valves all communicate the freezer. When the heat exchanger is communicated, the cooling water return water and the low-temperature water in the water storage tank finish heat exchange in the heat exchanger, so that the temperature of the cooling water is reduced. Thereby effectively utilizing the low-temperature water in the outdoor water storage tank in winter to cool the cooling water.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
