Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
The air conditioner 1 in the present application performs a refrigeration cycle of the air conditioner 1 by using a compressor 100, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 100. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner 1 can adjust the temperature of the indoor space throughout the cycle.
The indoor heat exchanger 300 and the outdoor heat exchanger 200 function as a condenser or an evaporator. When the indoor heat exchanger 300 is used as a condenser, the air conditioner 1 is used as a heater in a heating mode, and when the indoor heat exchanger 300 is used as an evaporator, the air conditioner 1 is used as a cooler in a cooling mode.
An air conditioner 1 according to an embodiment of the present invention is described below with reference to fig. 1 to 6, including: a compressor 100, an outdoor heat exchanger 200, an indoor heat exchanger 300, a first throttling element 400, a four-way valve 500, a water tank 600, and an in-tank heat exchanger 700.
Specifically, the first throttling element 400 is connected between one end of the outdoor heat exchanger 200 and one end of the indoor heat exchanger 300; the four-way valve 500 has a first port 510, a second port 520, a third port 530, and a fourth port 540, the first port 510 being connected to the outlet of the compressor 100, the second port 520 being connected to the other end of the outdoor heat exchanger 200, the third port 530 being connected to the inlet of the compressor 100, and the fourth port 540 being connected to the other end of the indoor heat exchanger 300; and, the in-tank heat exchanger 700 is disposed in the water tank 600, one end of the in-tank heat exchanger 700 is connected to an outlet of the compressor 100 and the other end is connected between one end of the indoor heat exchanger 300 and one end of the outdoor heat exchanger 200.
It is understood that, as shown in fig. 2, during the heating mode of the air conditioner 1, the refrigerant is discharged from the outlet of the compressor 100, and enters the four-way valve 500 through the first port 510, and then passes through the fourth port 540, such that the refrigerant can flow through the sequence from the indoor heat exchanger 300 to the outdoor heat exchanger 200, and returns to the four-way valve 500 through the second port 520, and then returns to the compressor 100 through the third port 530 to complete the cycle. The first throttling element 400 is adapted to throttling and depressurizing so as to facilitate the circulation of the refrigerant.
In this way, the refrigerant radiates heat in the indoor heat exchanger 300 so that the indoor heat exchanger 300 can radiate heat, thereby achieving the heating performance of the air conditioner 1. And before the refrigerant enters the four-way valve 500 from the compressor 100, the refrigerant can enter the in-tank heat exchanger 700, so that the heat of the refrigerant acts on the water tank 600 through the in-tank heat exchanger 700, the water tank 600 is heated, and the refrigerant after the heat exchange is introduced into the outdoor heat exchanger 200 and returns to the compressor 100 for subsequent circulation.
Therefore, the refrigerant driven to circulate in the compressor 100 can not only release heat and warm on the indoor heat exchanger 300, but also can be introduced into the tank heat exchanger 700 to heat the water tank 600, so that the efficiency of heating the moisture in the water tank 600 is improved.
Furthermore, as shown in fig. 3, during the cooling mode operation of the air conditioner 1, the refrigerant is discharged from the outlet of the compressor 100 and circulates through the outdoor heat exchanger 200 and the indoor heat exchanger 300 in this order, and the refrigerant absorbs heat during operation in the indoor heat exchanger 300, and this heat is generally dissipated in the outdoor heat exchanger 200 during the circulation process, resulting in waste of heat. Therefore, the in-box heat exchanger 700 is connected between the four-way valve 500 and the indoor heat exchanger 300, heat can be fused into the in-box heat exchanger 700 through the circulation of the refrigerant to heat moisture, the heating performance of the in-box heat exchanger 700 can be improved, and heat absorbed by the indoor heat exchanger 300 can be recycled, so that the influence of the use of the air conditioner 1 on the environment is reduced, and the use and operation of the air conditioner 1 are more energy-saving and environment-friendly.
Of course, as shown in fig. 1, the in-tank heat exchanger 700 alone can exchange heat with the water tank 600 so that the in-tank heat exchanger 700 alone can heat the water tank 600 so that the air conditioner 1 can provide hot water when not yet started.
According to the air conditioner 1 of the embodiment of the present invention, the in-box heat exchanger 700 is connected between the outlet of the compressor 100 and the outdoor heat exchanger 200, and the in-box heat exchanger 700 can participate in the refrigerant circulation of the air conditioner 1 in the heating mode to heat the water tank 600, so that the usability of the in-box heat exchanger 700 is improved; and the heat exchanger 700 in the lower box in the cooling mode can absorb the surplus heat to improve the usability of the heat exchanger 700 in the box. Meanwhile, the in-tank heat exchanger 700 can perform circulation heating independently, so that the water tank 600 can be made into hot water well under various conditions for use. In addition, because the in-box heat exchanger 700 can be used by absorbing the redundant heat during working, the heat can be recycled, and the in-box heat exchanger 700 is more energy-saving and environment-friendly.
In some embodiments, as shown in fig. 1 to 3, the air conditioner 1 further includes: and a first control valve 810, wherein the first control valve 810 is connected between one end of the tank heat exchanger 700 and the outlet of the compressor 100, and the first control valve 810 is used for controlling the on-off and the flow between the tank heat exchanger 700 and the compressor 100.
It is understood that the first control valve 810 is adapted to control the on/off and flow rate of the refrigerant introduced into the in-tank heat exchanger 700, and the first control valve 810 may be selectively closed to block the flow of the refrigerant through the in-tank heat exchanger 700 when the in-tank heat exchanger 700 is not required to be used. Or, when the performance of the in-tank heat exchanger 700 does not need to be significantly improved, the first control valve 810 may be controlled to maintain a smaller opening degree of the first control valve 810, so that the flow rate of the refrigerant flowing through the first control valve 810 is reduced, thereby completing the control and adjustment of the heat exchange performance of the indoor heat exchanger 300. In this way, the first control valve 810 is provided to control and adjust the flow rate of the refrigerant passing through the first control valve, so that the adjustment and control process of the in-box heat exchanger 700 can be simplified, and the in-box heat exchanger 700 can be used more simply and conveniently.
In some embodiments, as shown in fig. 1 to 3, the air conditioner 1 further includes: and a second control valve 820 having one end connected to the other end of the in-box heat exchanger 700 and the other end connected between one end of the indoor heat exchanger 300 and one end of the outdoor heat exchanger 200, the second control valve 820 being used to control the on/off and flow rate between the in-box heat exchanger 700 and the outdoor heat exchanger 200.
It is understood that the second control valve 820 is disposed at both ends of the in-tank heat exchanger 700 opposite to the first control valve 810 and functions similarly, when the performance of the in-tank heat exchanger 700 is switched or adjusted, the first control valve 810 may be selectively switched or adjusted, and the second control valve 820 may be selectively switched or adjusted, and the adjustment and control effects of the second control valve 820 are the same as those of the first control valve 810. Therefore, providing the second control valve 820 in the air conditioner 1 can further simplify the control process of the in-box heat exchanger 700, thereby facilitating the controlled use of the in-box heat exchanger 700.
In some embodiments, as shown in fig. 1 to 3, the air conditioner 1 further includes: and a second throttling member 830, one end of the second throttling member 830 being connected to the other end of the in-tank heat exchanger 700 and the other end being connected between one end of the indoor heat exchanger 300 and one end of the outdoor heat exchanger 200.
It can be understood that, similar to the first throttling element 400, the second throttling element 830 may be an electronic expansion valve, and the electronic expansion valve has the functions of throttling and reducing pressure, so that the refrigerant can better participate in subsequent circulation, and the circulation of the air conditioner 1 is more stable and reliable, and the refrigerant circulating in the air conditioner 1 can circulate according to the design, so as to form the service performance of the air conditioner 1. In this way, by providing the second throttling element 830 in the air conditioner 1, the refrigerant circulating in the air conditioner 1 is further throttled and depressurized, so that the air conditioner 1 is more stably and reliably used. Meanwhile, the second throttling element 830 is arranged to enable the flow rate of the refrigerant flowing in the air conditioner 1 to be lower, so that the control valve can better control the flow of the refrigerant.

In this way, the third control valve 840 is disposed between the indoor heat exchanger 300 and the four-way valve 500, so that the flow rate of the refrigerant entering the indoor heat exchanger 300 can be controlled and adjusted, and the flow rate of the refrigerant circulating in the indoor heat exchanger 300 can be better controlled, so that the performance adjustment and use of the indoor heat exchanger 300 are simpler and more reliable, and the control and adjustment process of the air conditioner 1 is simplified.
