Description

Technical Field

[0002] At present, the market usually uses refrigeration and dehumidification devices to cool and dehumidify energy storage batteries. Refrigeration and dehumidification machines can cool water vapor in the air to form water droplets, reduce the water content in the air, and achieve dehumidification effects. However, the surface temperature of the cooling coil of the refrigeration and dehumidification machine is difficult to control and is easily lower than 0°C. At this time, condensed water will freeze on the surface of the coil, reducing the cooling efficiency and dehumidification effect, so stable humidity cannot be obtained. In addition, the dehumidification effect of refrigeration and dehumidification is greatly affected by the ambient temperature. The dehumidification capacity will be significantly reduced after exceeding the reliable use temperature range. Utility Model Content

DETAILED DESCRIPTION

[0014] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0015] Please refer to Figure 1 The heat pump and rotary dehumidification system includes a first air flow path, a second air flow path, a first fluid flow path and a second fluid flow path. The second surface cooler, the rotary dehumidifier and the first surface cooler are arranged in sequence on the first air flow path; the condenser, the regeneration heater and the rotary dehumidifier are arranged in sequence on the second air flow path; the condenser, the throttle valve, the plate heat exchanger and the compressor are circulated and connected in sequence on the first fluid flow path; the plate heat exchanger, the liquid supply port and the liquid return port are circulated and connected in sequence on the second fluid flow path.

[0016] From the above description, it can be seen that the beneficial effect of the utility model is that when the temperature inside the energy storage container is too high and accompanied by high humidity, the first air flow path, the second air flow path, the first fluid flow path and the second fluid flow path start to operate. After the refrigerant is throttled by the throttle valve, it forms a first fluid with a lower temperature and enters the plate heat exchanger. In the plate heat exchanger, it completes heat exchange with the second fluid, that is, the battery coolant. The low-temperature second fluid enters the energy storage battery container to cool the battery and then enters the plate heat exchanger to cool it. This cycle is repeated to achieve a stable cooling effect of the energy storage battery container. At the same time, the high-humidity air in the energy storage container enters the second surface cooler to complete preliminary cooling, and then enters the rotary dehumidifier for dehumidification, which can improve the dehumidification efficiency of the dehumidifier, and then the dehumidified air is sent into the energy storage container. The regeneration wind enters the condenser to absorb the heat of the first fluid to form a preliminary temperature rise, and then enters the regeneration module of the rotary dehumidifier for regeneration after being heated by the regeneration heater, which can make full use of the waste heat of the condenser and reduce energy consumption. The utility model applies a rotary dehumidifier to humidity control of an energy storage container. The rotary dehumidifier has a wider applicable temperature range, more stable humidity control, and a more precise range, and can more reliably control the environment in the energy storage container within an appropriate humidity range.

[0017] Furthermore, the first air flow path also includes a first filter, a first fan and a second fan, and the first filter, the first fan, the second surface cooler, the rotary dehumidifier, the second fan and the first surface cooler are arranged in sequence along the transmission direction of the first air.

[0018] Furthermore, it also includes a temperature and humidity sensor, which is arranged at the air outlet end of the first surface cooler.

[0019] Furthermore, it also includes a regulating valve, a plate heat exchanger and a second surface cooler are cyclically connected, and the plate heat exchanger, the regulating valve and the first surface cooler are cyclically connected in sequence.

[0020] From the above description, it can be seen that the high-humidity air in the energy storage container enters the second cooler, exchanges heat with the second fluid with a lower temperature to complete preliminary cooling, and then enters the rotary dehumidifier for dehumidification, which can improve the dehumidification efficiency of the dehumidifier. The temperature and humidity sensor is used to accurately control the internal environment of the container. If the air temperature after dehumidification by the rotary dehumidifier is high, the second fluid can enter the cooler through the control of the regulating valve to cool the air, so as to achieve the purpose of temperature and humidity control, with higher efficiency and reliability.

[0021] Furthermore, it also includes a water pump, the water outlet of the water pump is connected to the plate heat exchanger, and the water inlet of the water pump is connected to the liquid return port, the first surface cooler and the second surface cooler.

[0022] Furthermore, the second air flow path also includes a second filter, a blower and a regeneration blower. The second filter, condenser, blower, regeneration heater, regeneration blower and rotary dehumidifier are arranged in sequence along the second air transmission method.

[0023] Please refer to Figure 1 Embodiment 1 of the utility model is: a heat pump and rotary dehumidification system, including a first filter 1, a first fan 2, a second surface cooler 3, a rotary dehumidifier 4, a second fan 5, a first surface cooler 6, a temperature and humidity sensor 7, a second filter 8, a condenser 9, a blower 10, a regeneration heater 11, a regeneration fan 12, a throttle valve 13, a plate heat exchanger 14, a compressor 15, a liquid supply port 16, a liquid return port 17, a regulating valve 18 and a water pump 19.

[0024] The first filter 1, the first fan 2, the second cooler 3, the rotary dehumidifier 4, the second fan 5, the first cooler 6 and the temperature and humidity sensor 7 are sequentially arranged along the transmission direction of the high humidity air in the energy storage container to form a first air flow path. The second filter 8, the condenser 9, the blower 10, the regeneration heater 11, the regeneration fan 12 and the rotary dehumidifier 4 are sequentially arranged along the transmission direction of the regeneration wind to form a second air flow path.

[0025] The condenser 9, the throttle valve 13, the plate heat exchanger 14 and the compressor 15 are connected in a circular manner to form a first fluid flow path. The plate heat exchanger 14, the liquid supply port 16, the liquid return port 17 and the water pump 19 are connected in a circular manner to form a second fluid flow path; the plate heat exchanger 14, the second surface cooler 3 and the water pump 19 are connected in a circular manner, and the plate heat exchanger 14, the regulating valve 18, the first surface cooler 6 and the water pump 19 are connected in a circular manner.

[0026] The operation process of the utility model is:

[0027] When the temperature inside the energy storage container is too high and accompanied by high humidity, the first air flow path, the second air flow path, the first fluid flow path and the second fluid flow path start to operate.

The low-temperature second fluid enters the energy storage battery container to cool the battery, and then enters the plate heat exchanger 14 to cool it down. This cycle is repeated to achieve a stable cooling effect of the energy storage battery container.

[0028] At the same time, the first fan 2 in the first air flow path extracts high-humidity air in the energy storage container, enters the second surface cooler 3 through the first filter 1 to complete preliminary cooling, and then enters the rotary dehumidifier 4 for dehumidification; the dehumidified air passes through the first surface cooler 6 and the temperature and humidity sensor 7 in sequence under the action of the second fan 5. If the temperature and humidity sensor 7 senses that the temperature of the dehumidified air is high, the regulating valve 18 is opened, and the second fluid enters the first surface cooler 6 under the action of the water pump 19 and the regulating valve 18 to cool the dehumidified air.

[0029] In the second air flow path, the blower 10 directly draws regeneration air from the outside. After passing through the second filter 8, the regeneration air enters the condenser 9 to absorb the heat of the first fluid to form a preliminary temperature rise, and then is heated by the regeneration heater 11 and enters the regeneration module of the rotary dehumidifier 4 for regeneration under the action of the regeneration fan 12.
