Technical Field
[0001] This utility model relates to the field of circulating water utilization technology, and in particular to an integrated circulating water cooling and heating system. Background Technology
[0002] In numerous pharmaceutical plants, circulating water systems have become indispensable core facilities, widely used in all stages of pharmaceutical production. Circulating water systems play a crucial role in key functions such as reaction temperature control, equipment cleaning, environmental maintenance, and energy optimization. However, most circulating water systems currently used in biopharmaceutical processing can only provide circulating water at a single temperature. Because different stages of the production process have diverse requirements for circulating water temperature, existing single-temperature circulating water systems can no longer meet production requirements and urgently need improvement and optimization. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an integrated circulating water cooling and heating system to solve the problem of single circulating water temperature in existing systems.
[0004] To solve the above-mentioned technical problems, this utility model provides an integrated circulating water cooling and heating system, including a first branch, on which a hot water tank, a condenser, a circulating pump, and water-using equipment are connected in sequence. The hot water tank, condenser, circulating pump, and water-using equipment constitute a circulating water circuit. The system also includes a second branch, one end of which is connected to the inlet of the circulating pump and the other end of which is connected to the inlet of the condenser. A first flow valve is provided on the second branch, and the water temperature in the water-using equipment can be adjusted by adjusting the opening size of the first flow valve.
[0005] In the preferred embodiment, a heating coil is installed inside the hot water tank, and the heating coil is connected to a solar energy device.
[0006] In the preferred embodiment, a third branch is also included, on which a cold water tank and a second flow valve are provided. The cold water tank and the second flow valve are connected to the circulating pump and the water-using equipment, forming a circulation loop. A first valve is also provided on the first branch connected in parallel with the second branch.
[0007] In the preferred embodiment, the third branch line shares a pipeline with the first branch line, a fourth valve is installed between the water-using equipment and the hot water tank, and a fifth valve is installed between the water-using equipment and the cold water tank.
[0008] In a preferred embodiment, a second valve is provided on the first branch, a fourth branch is provided in parallel with the second valve, and a third valve and a filter are provided on the fourth branch.

[0010] In the preferred embodiment, a water supply pipe is also provided above the cold water tank, and a sixth valve is provided on the water supply pipe.
[0011] The beneficial effects of this utility model are as follows: when the water-using equipment needs hot water, the first flow valve is opened and the first valve is closed; when the water-using equipment needs cold water, the first flow valve is closed and the first valve is opened; when warm water is needed, the first valve is opened and the flow rate is adjusted. By adjusting the ratio of cold water from the condenser to hot water from the first flow valve, the water temperature can be adjusted. This achieves the adjustment of multiple water temperatures and solves the problem of the original single water temperature. Attached Figure Description

Detailed Implementation
[0015] Please see Figure 1 As shown, this application provides a technical solution: an integrated circulating water cooling and heating system includes a first branch 11, on which a hot water tank 12, a condenser 13, a circulating pump 14, and a water-using device 15 are connected in sequence. The hot water tank 12, condenser 13, circulating pump 14, and water-using device 15 constitute a circulating water circuit. The system also includes a second branch 16, one end of which is connected to the inlet of the circulating pump 14, and the other end is connected to the inlet of the condenser 13. A first flow valve 17 is provided on the second branch 16, and the water temperature in the water-using device 15 is adjusted by adjusting the opening size of the first flow valve 17.
[0016] In this way, when the water-using equipment needs hot water, the first flow valve is opened and the first valve is closed; when the water-using equipment needs cold water, the first flow valve is closed and the first valve is opened; when warm water is needed, the first valve is opened and the flow rate is adjusted. By adjusting the ratio of cold water from the condenser to hot water from the first flow valve, the water temperature can be regulated.
[0017] In a preferred embodiment, a heating coil 18 is provided inside the hot water tank 12, and the heating coil 18 is connected to the solar energy device 19.
[0018] This method uses a solar energy device to heat the heating coil, thereby heating the water in the hot water tank.
[0019] In the preferred embodiment, a third branch 21 is also included, on which a cold water tank 22 and a second flow valve 23 are provided. The cold water tank 22 and the second flow valve 23 are connected to the circulating pump 14 and the water-using equipment 15, forming a circulation loop. A first valve 24 is also provided on the first branch 11, which is connected in parallel with the second branch 16.
[0020] This is equivalent to adding a cold water branch. By adjusting the ratio of the flow rate of the second flow valve on the third branch to the hot water flow rate of the first flow valve, the water temperature in the water-using equipment can be regulated.
[0021] In the preferred embodiment, the third branch 21 shares a pipeline with the first branch 11, a fourth valve 25 is provided between the water-using equipment 15 and the hot water tank 12, and a fifth valve 26 is provided between the water-using equipment 15 and the cold water tank 22.
[0022] In this way, when the water in the hot water tank is insufficient, water can be replenished by opening the fourth valve and closing the fifth valve through the third branch, which shares a pipe with the first branch.
[0023] In a preferred embodiment, a second valve 27 is provided on the first branch 11, a fourth branch 28 is provided in parallel with the second valve 27, and a third valve 29 and a filter 31 are provided on the fourth branch 28.
[0024] The purpose of this design is to address the issue that scale buildup occurs during long-term heating in the hot water tank. When scale needs to be removed, the second valve is closed and the third valve is opened, allowing hot water to flow through the filter and remove the scale.
[0025] In a preferred embodiment, temperature sensors are provided in the hot water tank 12, the cold water tank 22, and the water-using equipment 15.
[0026] Setting a temperature sensor allows for better adjustment of the opening size of the second and first flow valves, thereby achieving the preset water temperature.
[0027] In a preferred embodiment, a water supply pipe 32 is provided above the cold water tank 22, and a sixth valve 33 is provided on the water supply pipe 32.
[0028] By opening the sixth valve, water can be replenished to the cold water tank.
[0029] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
