Description

Air conditioning heat exchange condenser and spray evaporative cooling system

The invention belongs to a cooling device for an air conditioner, and is specifically an air conditioning heat exchange condenser and a spray evaporative cooling system. Background technique

The summer climate is hot and air-conditioning refrigeration equipment is used in large quantities. In winter, the weather is cold and air conditioning equipment is also widely used. Today, when energy is getting tighter, how to save energy, reduce the power consumption of air-conditioning equipment, and effectively improve energy utilization have become the top priority today.

Most of the current air conditioning and refrigeration equipment is a wind cooling system. The liquid refrigerant enters the evaporator to absorb heat and becomes a vapor state. The vaporized refrigerant is compressed into a high-density gas by a compressor, and then condensed by a heat exchanger. The device condenses into a liquid and releases a large amount of heat. At this time, only the fan blows the heat to cool the heat exchanger. Especially in the high temperature season, due to the high air temperature, a large amount of heat released by the gas refrigerant during condensation into a liquid cannot be quickly discharged, so that the temperature of the condenser rises to about 90-120 ° C, thereby preventing the condensation process of the refrigerant. At this time, only the compressor is increased in pressure to force the condensation agent to condense, and the high-load operation of the compressor wastes both electrical energy and shortens the service life of the internal mechanical structure of the compressor. During the entire cooling cycle, the power consumption of the air conditioner mainly comes from the heat exchanger group. If the cooling and cooling efficiency from the compressor to the heat exchanger is improved, and the refrigerant condensation temperature is greatly reduced, the compressor can be used lower. The critical pressure causes the refrigerant to condense. Therefore, the compressor reduces the output power of the motor during the entire cycle due to light load operation, thereby achieving energy saving.

When the refrigerant gas enters the heat exchanger for heat exchange, a large amount of heat is released, and this part of energy is lost regardless of which cooling method is used. If this kind of energy that seems to have to be worn out can be absorbed and reused, it can also achieve the purpose of saving energy and reducing consumption.

In the cold winter, the condenser of the outdoor unit of the heating type air conditioner is converted into an evaporator, and it is difficult to absorb the heat energy from the air of minus ten degrees. Moreover, the heat exchanger fins are also prone to frost and blockage, making heat absorption more difficult, and it is necessary to heat the defrosting before continuing. Continued work, resulting in waste of electrical energy. If the evaporator can absorb the energy of the active constant temperature water, it is relatively easy to heat the air conditioner.

The current air conditioners, because of the installation of indoor units and outdoor units, make the air conditioning lines too long and have many bends. This not only increases the energy consumed by the frictional force when the liquid flows, but also consumes cooling energy. In the process of installation or transfer, the split type air conditioning and refrigeration equipment will inevitably cause leakage of refrigerant and bring pollution to the environment. If the heat exchanger and the air conditioner can be integrated into one, the length of the pipeline can be shortened, and the elbow of the heat exchanger can be reduced, thereby saving energy and reducing consumption.

In addition, since air-conditioning and refrigeration equipment are generally installed in relatively closed rooms, air replacement in the room is relatively difficult, and working in such an air-conditioned room where air does not flow for a long time poses a certain threat to human health. If you can replace the indoor air without opening the doors and windows, it will definitely bring people a more comfortable living environment. Summary of the invention

During heating and hot water production, the constant temperature water source can take ground water, after being absorbed by heat. Returned to the ground, which absorbs energy without damaging the resource environment.

Since all the heat dissipating components of the system use cooling and heat preservation to prevent heat leakage, it is suitable for indoor installation.

When the cooling water is applied to the low water mark, the low water level switch Κ2 is turned on, and the two-way solenoid valve 206 is closed, at which time the hot water in the heat exchanger enters the hot water tank 60 from the one-way check valve 403. This completes the hot water collection process.

When the hot water tank 60 is full and begins to overflow, it is sprayed by the check valve 404 to the shower head 401 to cool. When the water level of the water reservoir reaches the high water level line, the high water level switch K1 is turned on, the electromagnetic valve 209 is closed, the water source stops supplying water, and the water pump 302 is turned on at the same time. The water starts the water circulation cooling operation through the two-way solenoid valve 405, the second four-way two-way switching valve 202, and the outer copper tube lower port 105. The water outlet pipe of the pump is sleeved with a rubber tube to facilitate disassembly and cleaning.

When the water evaporation in the water trap is reduced to the lower water level, the high and low water level switches Kl, Κ2 are disconnected, the water pump 302 is turned off, and the electromagnetic valve 209 is turned on, and the cooling water source continues to supply water. This starts the above cycle again.

When heating:

The first and second four-way bidirectional switching valves 201, 202 are simultaneously electrically switched, and the two-way solenoid valves 204, 209, 208 are electrically opened.

After the refrigerant is compressed by the compressor 303, the output high-pressure refrigerant gas passes through the first four-way two-way switching valve 201, the two-way electromagnetic valve 204, and then heat exchange to the heat exchanger 100 to become a liquid, and simultaneously releases heat, liquid refrigerant After entering the second heat exchanger 102 via the dryer and the capillary 203, the heat is absorbed, and the gas is turned into a gas, and then returned to the compressor through the first four-way two-way switching valve 201.

The water source used for heating is a constant temperature water source, and the constant temperature water flow process is: the constant temperature water enters the upper port 106 of the second heat exchanger 102 via the two-way solenoid valve 209 and the second four-way two-way switching valve 202, in the second heat The exchanger 102 performs heat exchange, and the temperature of the water after the heat exchange is lowered. The low temperature water flows out from the lower port 105 of the second heat exchanger 102 through the second four-way two-way switching valve 202 and the two-way solenoid valve 208. The water discharged after the heat exchange can be returned to the constant temperature water source for recycle. The constant temperature water source can be groundwater or geothermal water, and the water discharged by heat exchange can be re-injected into the ground without affecting the groundwater volume.

Hot water:

The first and second four-way two-way switching valves 201, 202 are simultaneously electrically switched, and the two-way solenoid valves 205, 209, 208, 210 are electrically opened.

After the refrigerant is compressed by the compressor 303, the output high-pressure refrigerant gas passes through the second four-way two-way switching valve 202 and the two-way electromagnetic valve 205, passes through the upper port 110 of the first heat exchanger 101, and enters the first heat exchanger 101. The heat exchange, the refrigerant becomes a liquid, and a large amount of heat is released, and the liquid refrigerant flows out through the lower port 109 of the first heat exchanger 101, enters the second heat exchanger 102 via the dryer, the capillary 203, and the liquid refrigerant absorbs heat. After being turned into a gas, it is returned to the compressor 303 via the first four-way bidirectional switching valve 201.

When the hot water is used, a constant temperature water source is used, and the constant temperature water flow process is: the constant temperature water drawn by the water pump flows through the two-way electromagnetic valve 209, the second four-way two-way switching valve 202, and a part of the two-way electromagnetic valve 210 and the temperature-controlled flow valve 207, entering the heat exchanger 101 through the lower port 107 of the first heat exchanger 101 for heat exchange; and another portion entering the second heat exchanger 102 via the water shutoff switch K3 for heat exchange. The water heated by the first heat exchanger 101 flows out from the upper port 108 of the first heat exchanger 101, and the hot water enters the hot water tank 60 via the one-way check valve 403. The water temperature of the heat exchanger 102 is lowered by the water of the heat exchanger 102, which flows out of the water outlet 105 of the heat exchanger 102, and flows out through the second four-way switching valve 202 and the two-way solenoid valve 208.

In the system, the temperature-controlled flow valve 207 is used to control the temperature of the water flowing out of the first heat exchanger 101. When the water temperature exceeds the set value, the flow rate of the temperature-controlled flow valve 207 is increased, thereby flowing into the first heat exchanger 101. The amount of water increases, so that the temperature of the water flowing out of the first heat exchanger 101 drops. When the water temperature is lower than the set value, the flow rate of the temperature-controlled flow valve 207 is decreased, so that the amount of water flowing into the first heat exchanger 101 is decreased, so that the temperature of the water flowing out of the first heat exchanger 101 rises. Thereby, it is ensured that the temperature of the water flowing out through the first heat exchanger 101 is substantially maintained stable. The water shutoff switch K3 is used to monitor the flow of no water, and when the water flows, the water cut switch K3 is turned on, so that the compressor 303 and the draft fan 50 start to work; when the waterless flow passes, the water cut switch K3 is turned off, the compressor 303 And the induced draft fan 50 stops working. Referring to FIG. 5, in the two embodiments, the housing 40 is disposed at an upper portion of the water reservoir 301. In the opposite part of the casing 40 and the compressor 303, a water spray net 402 is disposed, and the shower head 401 is disposed on the upper part of the water spray net 402; a draft fan 50 is disposed on the upper part of the shower head 401, and the induced draft fan 50 is installed at On the casing 40, the induced draft fan 50 is provided with an air outlet 501 which is connected to the outdoor and directly extracts the induced draft fan 50 to exhaust the gas. Thereby, the function of extracting water vapor out of the room can be realized, and the indoor air can be evoked to keep the indoor air fresh. The water trap 301 is made of a double-layer rustproof material and is filled with a foam material between the interlayers.

The first four-way two-way switching valve 201 and the second four-way two-way switching valve 202 have mechanical linkage control, and when the air conditioner is switched to the heating and hot water heating function, the first and second four-way two-way switching valves 201, 202 The power is turned on at the same time.

6 is a cross-sectional view of the hot water tank 60 in a front view. The hot water tank 60 is a special construction and must be filled with a double layer of material to fill the insulation material. It has two water pipes, one inlet pipe 601, and also serves as a drain pipe when hot water is used. It is connected to the outlet pipe 603 through a valve at the lower part of the hot water tank, and can be used as a hot water source for washing. Since there is a one-way check valve 403, it is not possible to reflow as long as the water flows in. An overflow pipe 602, which is above the inlet pipe 601, due to cold, The specific gravity of hot water is different, hot water is on top, and cold water is below. Therefore, the water inlet of the overflow pipe 602 is at the bottom of the water tank. When the water level reaches the overflow level, the water flows out of the overflow pipe. In order to prevent the siphon phenomenon, the water is sucked dry, and two small holes A are drilled above the overflow pipe in the tank to prevent the siphon phenomenon.

To reduce environmental pollution, prevent refrigerant leakage during installation, disassembly, and transfer. The present invention can be integrated with the indoor unit heat exchanger 100 (i.e., the refrigerating and air conditioning evaporator) as an indoor unit. Since all the heat dissipating components of the system are cooled and insulated, the heat leakage is eliminated, so it is suitable for indoor installation.

Water is also a valuable resource. During cooling, when the hot water tank is full, the excess hot water is used for evaporative cooling and recycling, which avoids waste of water resources. During heating and hot water production, the constant temperature water source can take ground water, after being absorbed by heat. Returned to the ground, which absorbs energy without damaging the resource environment. Industrial applicability
