Therefore, they should not be construed as limitations on this utility model.
[0032] A chiller heat recovery component, such as Figures 1-3As shown, the system includes a heat recovery water tank 10 for chiller heat recovery, a heat exchange coil 70 inside the heat recovery water tank 10, a mixing mechanism 60 installed on the outer wall of the heat recovery water tank 10, a condensate inlet pipe 20 and a condensate outlet pipe 30 connected to both ends of the heat exchange coil 70 installed on the outer wall of the heat recovery water tank 10, and a cold water inlet pipe 40 and a hot water outlet valve 50 connected to the interior of the heat recovery water tank 10 also installed on the outer wall of the heat recovery water tank 10; the mixing mechanism 60 includes a mixer 61, the output shaft of the mixer 61 passes through the outer wall of the heat recovery water tank 10 and extends into its interior, and a stirring blade 63 is installed at the end of the output shaft of the mixer 61; a plurality of uniformly and equidistantly arranged heat exchange fins 71 are installed on the outer wall of the heat exchange coil 70, and the heat recovery is achieved through the set heat recovery... The heat exchange coil 70 inside the heat recovery tank 10 enables the condensation heat generated by the chiller to be effectively recovered and transferred to the water in the tank. Simultaneously, the mixing mechanism 60 installed on the outer wall of the heat recovery tank 10, especially the agitator 61 and its output shaft agitator blades 63, ensures a uniform water temperature distribution within the tank, improving heat recovery efficiency. Furthermore, the uniformly spaced heat exchange fins 71 on the outer wall of the heat exchange coil 70 enhance the heat exchange area, further improving the heat recovery effect. The condensate inlet pipe 20 and condensate outlet pipe 30 are connected to both ends of the heat exchange coil 70, enabling the circulation of condensate. The cold water inlet pipe 40 and hot water outlet valve 50 are respectively connected to the interior of the heat recovery tank 10, facilitating the input of cold water and the output of hot water.
[0033] Furthermore, fixing ears 11 are installed at the four corners of one side of the heat recovery water tank 10, so that the heat recovery water tank 10 can be easily installed and fixed in the designated position, thereby improving the stability and safety of the entire heat recovery assembly.
[0034] Specifically, the outer wall of the heat recovery water tank 10 is provided with an insulated outer shell 12. The insulated outer shell 12 is made of food-grade rubber and plastic cotton insulation sleeve with a thickness of 2-5mm, which effectively reduces heat loss during the heat recovery process, improves heat recovery efficiency, and ensures the safety and hygiene of the water quality.
[0035] The outer walls of the condensate inlet pipe 20, condensate outlet pipe 30, and cold water inlet pipe 40 are all equipped with identification tags 31, which enable operators to clearly identify the function and flow direction of each pipe, avoid misoperation, and improve the safety and convenience of operation.
[0036] In addition, the mixer 61 is provided with an anti-collision shell 62. The anti-collision shell 62 is made of metal and has a thickness of 1-3mm, which effectively protects the mixer 61 from external collisions and damage, extends its service life, and also improves the safety and reliability of the entire heat recovery assembly. The anti-collision shell 62 is connected to the outer wall of the heat recovery water tank 10 through the mounting ring seat 64, which facilitates installation or disassembly and makes the installation more secure and stable.
[0037] Working principle of the heat recovery component of this chiller:
[0038] First, such as Figure 4 As shown, cold water is introduced into the heat recovery water tank 10 through the cold water inlet pipe 40; at this time, the condensate inlet pipe 20 inputs the condensate generated by the chiller into the heat exchange coil 70. When the condensate flows in the heat exchange coil 70, its heat is transferred to the water in the heat recovery water tank 10 through the heat exchange fins 71 to achieve heat recovery.
[0039] Next, start the mixer 61. Its output shaft drives the stirring blade 63 to rotate inside the heat recovery water tank 10, stirring the water in the tank to ensure uniform water temperature distribution and improve heat recovery efficiency.
[0040] During the heat recovery process, operators can clearly identify the function and flow direction of each pipe by using the identification label 31, ensuring that the operation is correct.
[0041] Once heat recovery is complete, open the hot water output valve 50 to output the heated hot water from the heat recovery water tank 10 for user use; at the same time, the condensate output pipe 30 discharges the condensate after heat exchange from the heat exchange coil 70, completing the entire heat recovery process.
[0042] In addition, the heat recovery water tank 10 is insulated by the outer shell 12, which plays a role in heat preservation during the entire use process, reducing heat loss and improving heat recovery efficiency; while the fixing ears 11 ensure that the heat recovery water tank 10 can be stably installed in the designated position, and the anti-collision shell 62 protects the mixer 61 from external collisions and damage.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
