Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, the embodiment of the present invention provides a condenser cooling apparatus, which comprises a boiling heat exchange container 1 and a pressure maintaining system.

The boiling heat exchange container 1 has a receiving chamber 11, the receiving chamber 11 is configured to place a condenser 93 and a cooling liquid 12, the condenser 93 is placed in the receiving chamber 11, and the back shell is immersed in the cooling liquid 12. The boiling heat exchange container 1 is also provided with a steam outlet which can be arranged at the top of the boiling heat exchange container 1. The vapor outlet is communicated with the accommodating cavity 11, so that vapor generated after the cooling liquid 12 is boiled is discharged from the vapor outlet.

The pressure maintenance system comprises a vacuum device 2, the vacuum device 2 having an inlet port communicating with the vapour outlet via an inlet conduit 23.

The vacuum device 2 is configured to evacuate the accommodating cavity 11 to make the pressure of the accommodating cavity 11 reach a set pressure, and a boiling point (boiling temperature) of the cooling liquid 12 under the set pressure is lower than a condensing temperature of a refrigerant in the condenser 93, so as to cool the condenser 93 by using the boiling heat absorption of the cooling liquid 12. Specifically, the vacuum apparatus 2 evacuates the accommodating chamber 11 to reduce the pressure in the accommodating chamber 11, so as to reduce the boiling point of the cooling liquid 12 in the accommodating chamber 11, and after the pressure in the accommodating chamber 11 is reduced to a set pressure (which may be a set pressure range), the boiling point of the cooling liquid 12 at the set pressure can be reduced to be lower than the condensation temperature of the refrigerant in the condenser 93, so that the cooling liquid 12 having a temperature difference with the condenser 93 can absorb the heat discharged from the condenser 93 and boil. The operation of the vacuum device 2 enables the pressure in the accommodating cavity 11 to be maintained at a set pressure, and enables the cooling liquid 12 to continuously boil and absorb heat, so as to achieve the purpose of dissipating heat to the condenser 93 through the boiling and heat absorption of the cooling liquid 12. The vapor generated by the endothermic boiling of the cooling liquid 12 can be removed by the vacuum device 2, for example, to the outside.

The latent heat of vaporization of the cooling liquid 12 is utilized to carry heat in the boiling process of the cooling liquid 12, the carried heat is large, the consumed cooling liquid 12 is small, and the cooling effect of the condenser 93 is good, so that after the condenser 93 of the air conditioner is cooled by the condenser cooling equipment, the air conditioner does not need to be arranged into a split type structure, the condenser 93 does not need to be arranged in an outdoor unit, the requirement on the installation space of the air conditioner can be reduced, and the applicability of the air conditioner is improved.

In some exemplary embodiments, the cooling fluid 12 may be selected from water or an aqueous solution (i.e., formed by adding solutes to water), is low cost, is readily available, and is non-polluting. Other suitable liquids, such as other boiling heat absorbing media, may of course be used.

The condenser 93 may be cooled by three means, air cooling, liquid water cooling and boiling steam cooling: air cooling generally needs to be provided with an outdoor unit or a thicker exhaust pipe because the required condensation area is large; the liquid water cooling takes away the heat of the condenser 93 by using the temperature rise of water, if the liquid water is recycled, a cooling tower is needed, and if the liquid water is directly discharged, the water consumption is overlarge; the boiling steam cooling utilizes the vaporization latent heat gamma of water to carry heat, and the water consumption is low.

If the temperature difference of water before and after heat exchange is delta T degree

Heat Q carried by liquid water ₁ Can be expressed as:

Q ₁ ＝m ₁ c _p ΔT

heat quantity Q carried by boiling and vaporizing water ₂ Can be expressed as:

Q ₂ ＝m ₂ (c _p ΔT+γ)

in the formula, m ₁ 、m ₂ For water consumption, c _p About 4.2 kJ/(kg DEG C.) is the constant pressure specific heat capacity of water, and gamma is the latent heat of vaporization of water.

If the inlet water temperature is 20 ℃, the outlet water temperature and the steam temperature are both 70 ℃, and the vaporization latent heat gamma of the 70 ℃ water is about 2386kJ/kg, the same heat discharge amount (namely Q) ₁ ＝Q ₂ ) In the case, the ratio of water consumption for heat removal of liquid water and steam is:

therefore, compared with the liquid water cooling scheme, when the condenser 93 is cooled by adopting the scheme of the embodiment of the application, the water consumption can be reduced by 12 times, and the cost is favorably reduced; compared with the scheme of air cooling, when the scheme of the embodiment of the application is adopted to cool the condenser 93, the surface area of the condenser 93 can be reduced, the condenser 93 does not need to be arranged outdoors, namely, the air conditioner does not need to be arranged into a split type structure comprising an outdoor unit, but the air conditioner can be arranged into an integrated structure (namely, an all-in-one machine), so that the volume and the required installation space of the air conditioner are reduced, and the applicability of the air conditioner is improved.

The vacuum device 2 needs to compress the vapor (such as water vapor) formed by boiling the cooling liquid 12 from a low-pressure vacuum state to a pressure higher than 1 atmosphere, and then the vapor can be smoothly discharged into the atmosphere, and the temperature of the water vapor exceeds 100 ℃ during compression, so that the vacuum device 2 is overheated, and the service life of the device is influenced. Air is introduced through the gas ballast component in the process of compressing water vapor by the vacuum equipment 2, the partial pressure of the water vapor is reduced, so that the temperature of the water vapor is reduced to a certain extent, but the volume and the flow of the total compressed gas can be increased by the method, so that the heat dissipation of the vacuum equipment 2 is realized by arranging a heat dissipation system, the temperature of the vacuum equipment 2 is reduced, and the over-high temperature of the vacuum equipment 2 in the working process is prevented, so that the working performance and the service life are further influenced.

Therefore, the superheater 8 ensures that the steam entering the vacuum equipment 2 is in a superheated state, and prevents small droplets in the steam from colliding with blades and the like in the vacuum device to influence the operation of the vacuum device.

It will be appreciated that the small droplets in the vapour may not only be heated to a vapour using the superheater 8 to eliminate them, but may also be achieved by other means, such as: in other exemplary embodiments, the cooling apparatus further includes a dryer provided in the intake duct 23.
