[0002] Currently, existing technology, specifically Chinese patent 201710997351.8, describes a condensate circulation system and its air conditioner. The condensate circulation system includes an indoor unit, an outdoor unit, and a condensate outlet pipe. The indoor unit includes an evaporator; the outdoor unit includes a condenser; the indoor end of the condensate outlet pipe is connected to the indoor unit to collect condensate from the evaporator; the outdoor end of the condensate outlet pipe is connected to the outdoor unit to allow condensate to seep onto the condenser. However, issues with drainage still exist. Utility Model Content

[0003] The purpose of this invention is to provide a water heat exchanger that eliminates the need for condensate discharge, which features condensate collection and input into the circulating water circuit, eliminating the need for discharge.

[0004] This utility model is implemented as follows: a water heat exchanger that eliminates condensate discharge, characterized in that it includes a casing, a water heat exchanger, an inlet pipe and a return pipe connected to the water heat exchanger, a water receiving tray, a water pump, and a control device.

[0005] The inlet and return water pipes are connected to the inlet and outlet ends of the water heat exchanger, respectively. The water receiving tray is located at the bottom of the water heat exchanger. The water pump is connected to the water receiving tray and the return or supply water pipe. The control device is connected to the water pump. The water pump's drainage pressure is greater than the pressure in the inlet and return water pipe system.

[0006] The water heat exchanger that eliminates condensate discharge is characterized by the following: it also includes a water level sensor, which is located inside the water receiving pan; the water level sensor is connected to the control device.

[0007] The aforementioned condensate-free water heat exchanger is characterized by the fact that it also includes a one-way valve or an electrically operated shut-off valve.

[0008] A check valve or electric shut-off valve is installed between the outlet of the water pump and the return or supply pipe.

[0009] The water heat exchanger that eliminates condensate discharge is characterized by the fact that it also includes a water filtration device, which is located between the water receiving pan and the water pump.

[0010] This utility model relates to a water heat exchanger that eliminates the need for condensate discharge. With this design, there is no need to install a drainage device or a condensate collection device, thus reducing the need for subsequent maintenance. Attached Figure Description

[0012] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] like Figure 1 As shown, a condensate-free water heat exchanger includes a casing 1, a water heat exchanger 2, an inlet pipe 31 and a return pipe 32 connected to the water heat exchanger, a water receiving tray 4, a water pump 5, and a control device 6. The inlet pipe 31 is also called the water supply pipe.

[0015] The inlet pipe 31 and the return pipe 32 are connected to the inlet and outlet ends of the water heat exchanger 2, respectively. Condensate generated on the surface of the water heat exchanger during heat exchange with the air is collected in a drip tray 4, which is located at the bottom of the water heat exchanger 2. A water pump 5 is connected to the drip tray 4 and either the return pipe 32 or the inlet pipe 31. A control device 6 is connected to the water pump 5. The drainage pressure of the water pump 5 is greater than the pressure in the system connected to the inlet pipe 31 and the return pipe 32. With this structure, condensate is input into the water circulation system, achieving zero condensate discharge and eliminating the need for drainage pipes and condensate collection devices.

[0016] As a further improvement of this utility model, it also includes a water level sensor 7, which is installed inside the water receiving pan 4; the water level sensor 7 is connected to the control device 6. When the condensate in the water receiving pan reaches the set water level, the water level sensor 7 transmits a signal to the control device 6, and the water pump 5 starts working.

[0017] As a further improvement of this utility model, it also includes a one-way valve or an electric shut-off valve 8.

[0018] A one-way valve or an electric shut-off valve 8 is located between the outlet of the water pump 5 and the return pipe 32 or the inlet pipe 31. When an electric shut-off valve is used, the electric shut-off valve 8 is connected to the control device 6.

[0019] As a further improvement of this utility model, it also includes a water filtration device 9, which is disposed between the water receiving tray 4 and the water pump 5. This structure prevents contaminants from entering the water circulation system.

[0020] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
