Abstract

The utility model relates to a spraying-type air-cooled refrigerator, comprising a condenser with a heat radiating discharge pipe. A plurality of spray pipes are arranged on the outer wall of the heat radiating discharge pipe which is adjacent to the condenser. The spray pipes are provided with multiple atomization spray holes which is aligned to the heat radiating discharge pipe of the condenser for water spray. Thus, atomization water can be vaporized. The spray pipes are connected to a water outlet pipe of a water pump. A water inlet of the water pump is communicated with a water box arranged below the condenser. The utility model utilizes that the atomization water can be easily vaporized; a great amount of vaporized latent heat is taken away. Thereby, a high pressure steam state refrigerant can be rapidly condensed. The goal of condensing the refrigerant with high efficient can be achieved.

Description

The atomizing air cooling chiller

The utility model relates to refrigeration plant, and concrete is a kind of atomizing air cooling chiller.

Usually the working medium type of cooling of refrigeration machine is divided into water-cooled and air-cooled.The water-cooled unit can be done very greatly, this is because the heat capacity ratio of water is bigger, approximately big four times than dry air, because the heat capacity ratio less (0.24kcal/kg dry air) of air, summer, air themperature was high again, and this is very unfavorable to condensation working medium, arrived to a certain degree greatly at refrigeration machine refrigeration power, come with cold type mode or even impossible, this is the too big and bad realization of area because air quantity that it needs and heat are loose again.

But the air cooling chiller group is without cooling tower, and save the cover water circuit system that water cooling uses, therefore install more convenient, in middle-size and small-size refrigeration machine, has certain superiority, and on this basis, it is a great task on refrigeration circle that its existing type of cooling is carried out essence, the effective improvement.

The purpose of this utility model mainly is an innovation air cooling refrigeration agent condensation technology, be to be the major technique feature to carry out water spray at condenser surface, utilize the easy vaporization of atomized water and take away a large amount of latent heats of vaporization, thereby, reach the purpose of condensating refrigerant expeditiously promptly with the condensation of high pressure vaporized refrigerant.

The purpose of this utility model is achieved in that

A kind of atomizing air cooling chiller, comprise that one has the condenser of heat radiation comb, it is characterized in that: the outer wall of the heat radiation comb of close this condenser is provided with some sparge pipes, this sparge pipe has the atomizing spray hole of trooping to align the heat radiation comb water spray of condenser and makes the atomized water vaporization, described sparge pipe is connected in the outlet pipe of a water pump, the water inlet of this water pump is communicated with a water tank, and this water tank is arranged at the below of condenser.

The utility model has following actively useful effect:

This patent mainly is the cold-producing medium (working medium) that utilizes the latent heat of vaporization condensation refrigeration unit efficiently of water, the major technology problem is to carry out water spray at existing condenser surface, condenser surface is contacted with water smoke, and the water of vaporization will be taken away the heat of condenser surface in a large number with the form of heat of vaporization easily.

The air-cooled type of cooling of atomizing mainly is to utilize big especially this physical characteristic of the latent heat of vaporization of water, the latent heat of vaporization of water is 597.3kca1/kg, self-evident, if the high temperature of condenser surface is with the water vapor of 1kg, the heat of being taken away is 597.3kcal, the task that this dry air 829.6kg that is equivalent to 3 ℃ of temperature rises just can finish (water that is exactly 3 ℃ of temperature rises yet needs 199.1kg), in other words, if in air-cooled, add water spray, make its vaporization, even be not all to be vaporized, also can make several times of the air quantity of air cooling, tens times, even the minimizing of hundreds of times ground, this will mean air cooling power, the size of blower fan, the surface area of cooler etc. all will reduce widely, thereby material that make to make above-mentioned setting will save in a large number, and realization that the more important thing is this technology also will make the possibility that creates of large-sized wind cooling handpiece Water Chilling Units.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is the structural representation of the utility model one embodiment;

Accompanying drawing number:

1. condenser

2. sparge pipe

3. water pump

4. water tank

Atomizing air cooling chiller of the present utility model, comprise that one has the condenser 1 of heat radiation comb, the outer wall of the heat radiation comb of close this condenser 1 is provided with some sparge pipes 2, the heat radiation comb that this sparge pipe 2 has the atomizing spray hole of trooping to align condenser 1 sprays atomized water, the atomized water contact is dispelled the heat comb and is made the atomized water vaporization, described sparge pipe is connected in the outlet pipe of a water pump 3, the water inlet of this water pump 3 is communicated with a water tank 4, this water tank 4 is arranged at the below of condenser 1, not Qi Hua surplus current recovery tank 4.

Fig. 1 shows a V-type condenser embodiment, and the condenser of other shape for example enforcement principle of C shape condenser is identical therewith, and this specification is not given unnecessary details.

The enforcement of this patent is not difficult, the existing mature technique of Pen Wu realization at first, and it is very easy making water atomization with the method for high-pressure fog, and power consumption is very little, and the water that has atomized is easy to be vaporized.Air intake surface at existing air-cooled condenser installs high pressure sprays fog equipment additional, just can realize above-mentioned purpose, for continuous operation and formation product, can make a water tank in the bottom of existing condenser, a fluid level control valve is installed again, to carry out automatic water supplement, a simple water treatment facilities is installed on filling pipe again, just can become the complete atomizing air cooling chiller group of a cover.

Claims

1. atomizing air cooling chiller, comprise that one has the condenser of heat radiation comb, it is characterized in that: the outer wall of the heat radiation comb of close this condenser is provided with some sparge pipes, this sparge pipe has the atomizing spray hole of trooping to align the heat radiation comb water spray of condenser and makes the atomized water vaporization, described sparge pipe is connected in the outlet pipe of a water pump, the water inlet of this water pump is communicated with a water tank, and this water tank is arranged at the below of condenser.
