Problems solved by technology

[0003] In order to overcome the disadvantage that the existing central air conditioner is used for air conditioning to discharge the heat energy instead of using it, a hot water system using the waste heat of the central air conditioner is designed to use the heat energy discharged from the cooling medium to heat the sanitary hot water. The condensing pipe and the sanitary hot water heat exchange pipe are placed in one body for heat exchange, which saves steel and reduces the volume of the unit

Embodiment Construction

[0009] The high-temperature working medium gas discharged from the refrigeration main engine is condensed by the condensing tube in the heat exchanger, and the sanitary hot water is heated at the same time. In a condenser body, the cooling water and the sanitary hot water are separated and sealed, and different circulating water systems are used respectively to achieve While condensing the high-temperature working fluid gas, the sanitary hot water is heated at the same time.

[0010] According to the cooling power of the central air conditioner and the sanitary hot water flow required by the design, determine the ratio of the heat transfer area of ​​the sanitary hot water heat exchange tube to the working fluid gas condensation tube, and finally determine the total heat transfer area of ​​the shell and tube condenser.

Abstract

The invention relates to a water heating system using the waste heat from a central air conditioner. The technical background is that: the known central air conditioner is mainly used for air conditioning. The technical proposal of the invention is that: (1) a condenser with a condensing tube and a clean hot water exchange tube are arranged in a main body to realize the heat exchange, and the condensing tube, the clean hot water and the heat exchange tube are simultaneously arranged inside the mutually-hermetic main body; (2) a clean hot water circulating pump employs a frequency convertor to regulate the rotational speed and the rotational speed can be automatically switched among three preset modes; (3) a closed circulation system has two hot water tanks with different working pressures and automatically control the transfer and storage of hot water; and (4) in a flooded evaporator assembly, the current of cooling water is limited to solve the problem of oil accumulation in the evaporator.

Description

[0001] Belonging technical field; The present invention relates to a kind of hot water system utilizing central air-conditioning waste heat. Background technique; [0002] The main effect of present known central air conditioner is to be used for air conditioning. content of the invention; [0003] In order to overcome the disadvantage that the existing central air conditioner is used for air conditioning to discharge heat energy instead of using it, a hot water system using the waste heat of the central air conditioner is designed to use the heat energy discharged from the cooling medium to heat sanitary hot water, and the The condensing pipe and the sanitary hot water heat exchange pipe are placed in one body for heat exchange, which saves steel and reduces the volume of the unit. [0004] The sanitary hot water circulation pump adopts the frequency converter to regulate the speed, and the rotation speed automatically operates in the three preset modes. In the closed syst...
