Problems solved by technology

Generally, during freezing operation in summer, due to the unsatisfactory heat dissipation effect of the water tower, the cooling water temperature is too high (30-38°C) which will cause the freezing pressure to be too high (15-20 kg / cm 2 ), leading to poor cooling effect of the cooling equipment, affecting the cooling effect of the unit, and increasing energy consumption
[0003] In addition, due to the water tower heat dissipation method, the loss of cooling water is huge, and new cooling water needs to be added continuously. However, since tap water is used as cooling water now, after long-term operation, it will be in the heat exchange pipeline of the cooling equipment. The formation of scale will reduce the heat exchange efficiency and affect the cooling effect of the air conditioning unit

Embodiment 1

[0023] Different from the traditional water tower heat dissipation air conditioning unit, this scheme adopts a closed cooling equipment heat dissipation circuit, according to figure 1 As shown, this scheme includes organic unit body and cooling equipment; unit body includes air inlet, filter, chilled water surface cooler, water tray, cold recovery heat exchanger, fan, electric heater, air outlet; external air After entering the unit body from the air inlet, it passes through the filter, chilled water surface cooler, water receiving tray, cold recovery heat exchanger, fan, and electric heater, and then blows out from the air outlet; the cooling equipment includes a refrigerator, a heat dissipation circuit and a refrigeration unit. circuit; the chilled water surface cooler communicates with the refrigeration circuit of the cooling equipment through a cooling pipeline; the cold recovery heat exchanger is provided with a heat dissipation pipeline; the heat dissipation pipeline comm...

Embodiment 2

[0029] The difference from Embodiment 1 is that the water storage device is provided with a water spray pipe, and the water spray port of the water spray pipe extends to the air inlet; the water spray pipe is provided with a water spray pump. When there is a lot of cooling water stored in the water storage device, turn on the water spray pump to spray the cooling water at the air inlet to form water mist, reduce the air temperature at the air inlet, reduce the cooling load of the unit, and save energy.

Embodiment 3

[0031] Compared with Embodiment 1, the difference is that a second drain pipe is provided on the water receiving tray; a second water storage device is provided outside the unit body; the second drain pipe communicates with the second water storage device; the second water storage device A second water supply pipe communicating with the water supply pipe is arranged on the top; a second on-off valve is arranged on the second water supply pipe.

[0032] This setting can store excess condensed water separately in the second water storage device. The inside is condensed water, and the water hardness is zero. Cooperating with the spray cooling method in Example 2, after the original cooling water is sprayed out, concentrated Supplementing the condensed water with 0 hardness can quickly replace the original cooling water. With the help of electronic descaler, it can quickly realize the complete removal of hardness of the cooling water, fundamentally eliminate the generation of scale...

Abstract

The invention provides a water-cooled air-conditioning unit with a closed condenser heat dissipation circuit. The solution includes an organic unit body and cooling equipment; the unit body includes an air inlet, a filter, a chilled water surface cooler, a water tray, and a cooling recovery Heat exchanger, fan, electric heater, air outlet; the chilled water surface cooler communicates with the refrigeration circuit of the cooling equipment through the cooling pipeline; the cold recovery heat exchanger is provided with a heat dissipation pipeline; the heat dissipation of the heat dissipation pipeline and the cooling equipment The loop is connected. This solution adopts the addition of a cold recovery heat exchanger in the air conditioning unit and connects it with the heat dissipation circuit of the cooling equipment, changing the traditional water tower heat dissipation method, and using the cold air refrigerated by the air conditioner to cool the cooling water. Synchronization can also increase the temperature of the cold air and reduce the subsequent electricity The energy consumption of the heater is reduced, and compared with the traditional water tower cooling method, the cooling water cooling effect is better, which can effectively improve the heat dissipation efficiency of the cooling equipment and save energy.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a water-cooled air-conditioning unit with a closed condenser cooling circuit. Background technique [0002] In the prior art, water-cooled air conditioners use chilled water as the refrigerant in the air-conditioning unit, and the cooling equipment that cools the chilled water also uses water-cooled methods. Generally, a honeycomb heat dissipation water tower is built, and the cooling is discharged through the water tower. device heat. Generally, during freezing operation in summer, due to the unsatisfactory heat dissipation effect of the water tower, the cooling water temperature is too high (30-38°C) which will cause the freezing pressure to be too high (15-20 kg / cm 2 ), leading to poor cooling effect of the cooling equipment, affecting the cooling effect of the unit, and increasing energy consumption. [0003] In addition, due to the water tower heat dissipation method, the l...
