Embodiment 1

[0043] Embodiment 1: This embodiment provides an energy-saving water-cooled air conditioner, which uses medium water as a medium to input cold and heat into the room. Compared with traditional air-cooled heat pump air conditioners, it can save energy by more than 30%. Its structure is as follows: figure 1 shown; its operating principle is as follows figure 2 , image 3 , Figure 4 Shown; the block diagram of its control system is shown in Figure 10 shown.

[0044] The energy-saving water-cooled air conditioner provided in this embodiment is mainly composed of a cooling tower part and an equipment room part, and has four major systems of cooling water circulation, medium water circulation, control and refrigerant circuit. Use the medium water as the medium to input cold and heat into the room. In summer, the refrigerant is cooled by water cooling method, and in winter, the working principle of heat pump is used for heating. The equipment room part is in the lower part o...

Embodiment 2

[0091] Embodiment 2: An energy-saving water-cooled air conditioner that uses refrigerant as a medium to input cold and heat into the room.

[0092] The air conditioner provided by this embodiment can save energy by more than 30% than the traditional air-cooled heat pump air conditioner, and its structure is as follows: figure 1 As shown, its operation principle is as follows Figure 5 , Figure 6 Figure 7 shown.

[0093] The invention provides an energy-saving water-cooled air conditioner, which adopts a water cooling method to cool the refrigerant in summer, and uses the working principle of a heat pump to heat in winter. It is mainly composed of a cooling tower part and an equipment room part. The equipment room part is at the lower part of the cooling tower part (the equipment room and the cooling tower part can also be placed side by side), and they are connected by multiple pipes and wires. The air conditioner is equipped with three major systems of cooling water, co...

Embodiment 3

[0119] Embodiment 3: An integrated cold-only air conditioner composed of an effective combination of a cooling tower and a refrigeration host.

[0120] The air conditioner provided in this embodiment has a higher comprehensive energy efficiency ratio than the traditional water-cooled central air conditioner, can save about 30% of the initial equipment investment, and can save a large amount of equipment space. Its structure is as Figure 8 As shown, its operation principle is as follows Figure 9 shown.

[0121] This embodiment provides an integrated single-cooling air conditioner composed of an effective combination of a cooling tower and a refrigeration host. This air conditioner is mainly composed of a cooling tower part and an equipment room part, and is equipped with a large system of cooling water circulation, medium water circulation, and refrigerant circuit. Suitable for occasions that do not require air conditioning and heating. The equipment room part is in the lo...

Abstract

The invention provides an energy-saving water-cooled air conditioner which is mainly composed of a cooling tower part and an equipment room part. The cooling tower part and the equipment room part are placed in parallel or the cooling tower part is arranged on the upper portion of the equipment room part. The cooling tower part comprise a cooling tower, a water distribution pipe (22), a water distributor (23), a water-cooled cooling fin set (24), a water receiving plate (25), a heat exchanger (3), a windshield (29) and a pipeline. A water collection groove (26) is formed at one end of the cooling tower. A fan (28) is installed at the top of the cooling tower. The windshield (29) is installed below the heat exchanger (3). A control cabinet (7), a compressor (1), a condenser (2), a restricting element (5), an evaporator (4), a liquid storage tank (6), a medium water pump (20), a cooling water pump (21), a plurality of electrically operated valves, a plurality of check valves and a plurality of pipelines are arranged inside the equipment room part. According to the energy-saving water-cooled air conditioner, an air conditioning equipment machine room is eliminated, an indoor space is saved, and invested cost of purchase, installation and daily maintenance of cooling water pipelines is saved.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air-conditioning, and in particular to an air conditioner which utilizes circulating cooling water to dissipate heat through a water-cooling fin group during cooling, and utilizes a heat pump principle for heating during heating. Background technique [0002] In the existing HVAC technology field, especially the water-cooled central air-conditioning unit that uses cooling tower water circulation to cool down, the energy efficiency ratio (COP value) of the unit during cooling is high, which can be as high as 5.0 or more, but it cannot be heated in winter and requires external power. , gas, coal-fired boilers and other heat sources for heating. Although the air-cooled heat pump unit has a heating function, the energy efficiency ratio (COP value) during cooling is low, only about 3.0, which is not conducive to energy conservation and environmental protection. [0003] At present, most manufac...
