Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology, and in particular to a portable air conditioner with a condenser. Background Technology
[0002] The portable air conditioners we use today all have an evaporator placed on a drip tray, which in turn sits on top of the condenser. When the portable air conditioner is in cooling mode, the refrigerant condenses in the condenser and then flows into the expansion valve. After being throttled by the expansion valve, the refrigerant flows into the evaporator. The refrigerant flow path is as follows: Figure 1 The arrows indicate the direction of refrigerant flow. During refrigeration operation, the condensate produced on the evaporator is collected in the drip tray and then flows through the small holes or water trough on the drip tray to the condenser. From there, it flows to the bottom of the condenser and is drained through the drain hole, or it is pumped onto the condenser by a water jet.
[0003] However, during the implementation of the above technical solution, at least the following technical problems were found: During cooling, the temperature of the condensate on the evaporator is around 15°C. Such low-temperature water is not fully utilized; it is either directly drained or pumped up by a water-pumping impeller, which is somewhat wasteful. The temperature of the refrigerant at the condenser outlet is around 35°C, and this low-temperature condensate can be used to further cool the refrigerant flowing out of the condenser. Therefore, to solve the above problems, we propose a portable air conditioner with a built-in condenser. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a portable air conditioner with a condenser, which solves the technical problem that during cooling, the condensate on the evaporator has a low temperature but is not fully utilized, and is either directly drained or blown up by a water pump, resulting in waste.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A portable air conditioner with a condenser includes an evaporator, a drip tray, a first condenser, and a throttling device. The drip tray contains at least one second condenser. The inlet of the second condenser is connected to the water collection area of the drip tray, and the outlet of the second condenser is discharged to the outside or recycled through a drainage structure. After the refrigerant is initially condensed by the first condenser, it enters the second condenser and is further cooled by the low-temperature condensate in the drip tray. Then, it is throttled by the throttling device and enters the evaporator for circulation.
[0009] Preferably, the second condenser is a tube-fin or plate heat exchanger, and a water level monitoring device is installed in the water receiving pan.
[0010] Preferably, the drip tray includes a condensate recovery system, and a temperature regulating valve is provided between condenser one and condenser two. The installation position and size of condenser two are optimized to ensure that it can fully contact the condensate for heat exchange without affecting the overall structure and operational stability of the portable air conditioner.
[0011] (III) Beneficial Effects
[0012] First, the portable air conditioner with a super-condenser, by adding a second condenser, successfully utilizes the low-temperature condensate produced by the evaporator to further cool the refrigerant. This improvement allows the refrigerant to receive additional cooling in the super-condenser after flowing through the condenser, thus significantly reducing its temperature. The lower-temperature refrigerant, upon entering the evaporator, can more efficiently absorb indoor heat, achieving a faster cooling effect. Simultaneously, due to the improved cooling efficiency, the overall energy efficiency ratio of the air conditioning system also increases, reducing energy consumption and achieving the goal of energy conservation and emission reduction.
[0013] Second, in traditional portable air conditioners, the condensate produced by the evaporator is often directly discharged or treated by a water pump, resulting in a waste of water resources. Portable air conditioners with a super-condenser cleverly utilize this low-temperature condensate by introducing it into the super-condenser to exchange heat with the refrigerant, thus achieving effective use of water resources. In addition, some designs also include a condensate recovery system, which collects the condensate after heat exchange, filters and cools it, and then reuses it in the drip tray, forming a water recycling system. This design not only reduces water waste but also lowers the operating costs of the air conditioning system. Attached Figure Description

[0018] This application provides a portable air conditioner with a condenser, which effectively solves the technical problem that during cooling, the condensate on the evaporator has a low temperature but is not fully utilized and is either directly drained or blown up by a water pump, resulting in waste. Example
[0019] according to Figure 1 and Figure 2 As shown, the technical solution in this application embodiment effectively solves the technical problem that during refrigeration, the condensate on the evaporator has a low temperature but is not fully utilized, and is either directly drained or blown up by a water pump, resulting in waste. The overall idea is as follows:
[0020] To address the problems existing in the prior art, this utility model provides a portable air conditioner with a condenser, including an evaporator 1, a water tray 2, a first condenser 3, and a throttling device 4. The water tray 2 contains at least one second condenser 5. The inlet of the second condenser 5 is connected to the water collection area of the water tray 2, and the outlet of the second condenser 5 is discharged to the outside or recycled through a drainage structure. After the refrigerant undergoes initial condensation in the first condenser 3, it enters the second condenser 5 and is further cooled by the low-temperature condensate in the water tray 2. Subsequently, it is throttled by the throttling device 4 and then enters the evaporator 1 for recycling. In a portable air conditioner with a condenser, the condensate on the evaporator 1 is collected in the drip tray 2. Once the water level is higher than the condenser 5 in the drip tray 2, it flows through the small hole or water tank in the drip tray 2 onto the condenser 3. During cooling operation, the refrigerant is condensed in the condenser 3 and flows out, then into the condenser 5. In the condenser 5, it is further cooled by the low-temperature condensate and flows into the expansion valve 4. The refrigerant is throttled in the expansion valve 4 and then flows into the evaporator 1. The temperature of the refrigerant is further reduced in the condenser 5.
[0021] Condenser 2 5 is a tube-fin or plate heat exchanger. Its structural design maximizes the heat exchange efficiency between the refrigerant and condensate. The water tray 2 is equipped with a water level monitoring device to monitor the condensate water level. When the water level reaches the preset height, the flow control device for condensate water to condenser 2 5 is activated or adjusted to ensure that the condensate water effectively cools the refrigerant. The water tray 2 includes a condensate water recovery system. This system collects the condensate water from the outlet of condenser 2 5, filters and cools it, and then partially or completely reuses it in the water tray 2, forming a cycle and reducing water waste. A temperature regulating valve is installed between condenser 1 3 and condenser 2 5 to automatically adjust the refrigerant flow rate into condenser 2 5 according to the refrigerant temperature or condensate water temperature to achieve the best cooling effect. The installation position and size of condenser 2 5 have been optimized to ensure that it can fully contact the condensate water for heat exchange without affecting the overall structure and operational stability of the portable air conditioner.
[0022] Working principle:
[0023] The first step involves the condensate on the evaporator 1 of the portable air conditioner with a condenser. After the condensate is collected in the drip tray 2, it flows through the small hole or water trough of the drip tray 2 onto the condenser 3. During cooling operation, the refrigerant is condensed in the condenser 3 and flows out, then into the condenser 5. In the condenser 5, it is further cooled by the low-temperature condensate and flows into the expansion valve 4. The refrigerant is throttled in the expansion valve 4 and then flows into the evaporator 1. The temperature of the refrigerant is further reduced in the condenser 5, resulting in a lower temperature of the refrigerant entering the evaporator. This allows the entire unit to achieve a larger cooling capacity and higher energy efficiency.
[0024] In the second step, the refrigerant, after initial cooling in the condenser, flows through the condenser 2 (5) in the water collection pan 2. In the subcondenser, the refrigerant exchanges heat again with the low-temperature condensate. Since the condensate produced by the evaporator 1 is at a low temperature, it can effectively absorb the residual heat in the refrigerant, further cooling the refrigerant and significantly reducing its temperature, thus improving its cooling capacity. As the refrigerant is further cooled in the subcondenser, its temperature and pressure decrease further, transforming it into a low-temperature, low-pressure gaseous state. Subsequently, this low-temperature, low-pressure refrigerant enters the expansion valve 4. After being throttled and depressurized, it enters the evaporator 1 for evaporation. In the evaporator, the refrigerant rapidly evaporates and absorbs heat from the indoor air, thereby achieving a cooling effect.
[0025] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
