Description

Technical Field

[0001] The invention relates to the field of evaporative cooling heat pump equipment, in particular to an evaporative cooling intensive module chilled water heat pump unit. Background Art

[0002] The evaporative cooling intensive module chilled water heat pump unit is a highly efficient, energy-saving and environmentally friendly temperature control device. It cleverly combines evaporative cooling technology with heat pump technology, and realizes cooling and heating functions through evaporative cooling and heat pump cycles. The unit uses evaporative cooling technology to reduce the temperature of water through heat exchange between air and water. At the same time, it combines the heat pump cycle to achieve heat transfer and utilization through the circulation of refrigerant. In cooling mode, the unit absorbs heat from indoors and discharges it to the outdoors; in heating mode, the unit absorbs heat from the outdoors and transfers it to the indoors. The principle of traditional evaporative temperature control devices is that the compressor is responsible for compressing the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure gas, and then the high-temperature and high-pressure gas is cooled by the condenser to turn it into a high-pressure liquid, and then it enters the evaporator to achieve cooling.

[0003] Among them, condensation is a link that converts high-temperature and high-pressure gas into high-pressure liquid. It is extremely important. No matter it is cooling or heating, it is necessary to convert gas into liquid for transportation. Traditional cooling and heat exchange basically uses a fan to drive the external air to flow through the condenser, so that the gas in it is cooled and condensed into liquid, and then the expansion valve is used to limit the expansion of the liquid, so that the liquid is changed into low-temperature gas and flows in the evaporation pipe, and then the cold air is blown out by the fan. However, in some scenes with high ambient temperature, when the fan drives the air through the condenser, the temperature difference between the inside and the outside is small, and the internal gas is converted into liquid inefficiently, resulting in unsatisfactory cooling and heating effects. However, with the development of industry, some manufacturers combine wet film humidification cooling technology with condenser cooling technology to enhance the cooling effect of the condenser.

[0004] Existing wet film cooling technologies generally use a fan to drive the gas through the wet film. When the gas passes through the wet film, it exchanges heat with the water film on the wet film, making the temperature of the passing gas low, thereby achieving the purpose of cooling the space. The cooling principle of the condenser is the same. The leaves have a good condensation effect in an environment with high ambient temperature.

[0005] However, because a wet film is used for cooling operations, when air passes through the wet film, it will drive the movement of water molecules, thereby increasing the humidity in the space. After long-term use, a large amount of water droplets will condense on the surface of the condenser. If not cleaned in time, the condenser may be corroded over time, causing leakage in the condenser and causing the refrigeration system to fail to operate normally. Summary of the invention

[0006] Based on this, the purpose of the present invention is to provide an evaporative cooling intensive modular chilled water heat pump unit to solve the technical problem of using a wet film for cooling operation. When air passes through the wet film, it will drive the movement of water molecules, thereby increasing the humidity in the space. After long-term use, a large amount of water droplets will condense on the surface of the condenser. If they are not cleaned in time, the condenser may be corroded over time, causing the condenser to leak and thus causing the refrigeration system to fail to operate normally.

[0008] By adopting the above technical scheme, the refrigeration liquid required for refrigeration is stored in the provided liquid storage device. In actual use, the coolant is compressed and pressurized by the compressor to become a high-temperature and high-pressure gas. Then, it is passed through the wet film condensation device through the four-way valve to condense the high-temperature and high-pressure gas into a high-pressure liquid. Then, the liquid is filtered through the filter and then passed through the expansion valve to instantly vaporize the high-pressure liquid into a low-temperature gas. Then, the low-temperature gas is continuously transported into the evaporation pipe and blown out by the fan. The first fan drives the air to pass through the wet film body, so that the wet film body cools the passing air and enters the device casing, so that the cooled gas contacts the condenser tube, thereby achieving a cooling effect. At the same time, the arc-shaped placement plate allows the condensed water to flow down along the arc surface to the water storage tank for collection, thereby preventing liquid accumulation from corroding the pipe.

[0014] By adopting the above technical solution, the power module is set to drive the transmission gear to rotate, and the upper gear block is cooperated to move the power module, thereby driving the scraper to scrape the bottom of the device shell to clean and collect the water accumulated on the surface.

The condenser 15 is fixedly arranged between the device housing 27 and the placement plate 11. The air is driven by the first fan 5 to pass through the wet film body, so that the wet film body cools the passing air and enters the device housing 27.

The power module 21 drives the transmission gear 39 to rotate. The power module 21 is fixed and does not rotate under the action of the scraper 19. Therefore, the transmission gear 39 cooperates with the tooth block 22 to rotate and move, which can drive the scraper 19 to move together. The guide groove 20 is arranged in an arc shape to cooperate with the bottom surface of the device housing 27 set in an arc shape, so that the scraper 19 can clean the inner bottom surface of the device housing 27 and collect the condensed water on its surface into the water storage tank 12 at one end.

In actual use, when passing through the guide plate 36, the air enters the device housing 27 through the guide grooves 38, and then the gas is guided by the provided guide blocks 37. At the same time, the gas collides with the guide blocks 37 first, so that the water vapor condenses on its surface, thereby reducing the amount of condensation on the inner bottom surface of the device housing 27 later.
