本发明的高温废水源(15～80℃的废热源)热泵系统是一种为充分利用废高温蒸发源(15～70℃的废热水源)而开发的一种新型热泵工程。主要由高蒸发源(45℃的热源)热泵热水设备、定温废水输送装置、废水利用中间水箱、循环加热水系统、热水储存系统、采暖水换热盘管、采暖风机盘管、采暖水供应系统、废水存放池(15～70℃的废热源)和热水供应系统等组成。The high-temperature waste water source (15-80°C waste heat source) heat pump system of the present invention is a new type of heat pump project developed for making full use of the waste high-temperature evaporation source (15-70°C waste heat source). It mainly consists of high evaporation source (heat source at 45°C) heat pump hot water equipment, constant temperature wastewater delivery device, intermediate water tank for wastewater utilization, circulating heating water system, hot water storage system, heating water heat exchange coil, heating fan coil, heating water It is composed of supply system, waste water storage pool (waste heat source at 15-70°C) and hot water supply system.
主要功能有：自来水的预热：通过废水利用中间水箱中的换热盘管对自来水进行预热，升温后的自来水方补充进储热水箱。通过这种预热方式提高使用能效。恒温控制废水利用中间水箱的水温：采用微电脑温度控制器的温度控制功能，控制定温废水输送装置输送废水的流量，使废水利用中间水箱的水温恒定。制热水：当储热水箱和恒温水箱的水温下降，机组自动启动高蒸发源(45℃的热源)热泵热水设备以及相应的循环加热水系统进行制热水运转。直接供暖：采暖风机盘管上的微电脑控制器输出指令需要进行采暖时，采暖水供应系统启动，通过水箱中的换热盘管与恒温水箱的热水进行热交换，升温后的采暖水通过风机盘管的强排风向房间直接供暖。The main functions are: Preheating of tap water: preheating the tap water by using the heat exchange coil in the intermediate water tank through the waste water, and the tap water after heating is replenished into the hot water storage tank. Improve energy efficiency through this preheating method. Constant temperature control of the water temperature of the intermediate water tank used by waste water: the temperature control function of the microcomputer temperature controller is used to control the flow of waste water transported by the constant temperature waste water conveying device, so that the water temperature of the waste water used in the intermediate water tank is constant. Hot water heating: When the water temperature of the hot water storage tank and the constant temperature water tank drops, the unit automatically starts the high evaporation source (45°C heat source) heat pump hot water equipment and the corresponding circulating heating water system for hot water heating operation. Direct heating: When the microcomputer controller on the heating fan coil unit outputs instructions for heating, the heating water supply system starts, and the heat exchange coil in the water tank exchanges heat with the hot water in the constant temperature water tank, and the heated heating water passes through the fan coil.

Through the use of the microcomputer temperature controller in the middle water tank for waste water, the amount of waste water added is intelligently controlled, effectively preventing damage to the heat pump hot water equipment with high evaporation sources (heat sources of 45°C) when the temperature of the used waste water exceeds 45°C Or report a fault and stop working. Through the high evaporation pressure of the heat pump hot water equipment with high evaporation source (heat source at 45°C), the energy efficiency of the unit exceeds 5.8. Utilize waste water to utilize the effect of the heat exchange coil in the intermediate water tank to increase the temperature of the supplemented tap water by 0-20°C and increase the energy efficiency ratio by 20%. Using the temperature relay heating principle of two-stage water tanks, the water temperature of the hot water storage tank only needs to be heated to 48°C, and the water temperature of the constant temperature water tank only needs to be heated from 48°C to 55°C. Through this relay heating method, the hot water supplied The water temperature is constant, achieving the effect of the direct heating unit. The two overflow outlet structures with different heights can well adapt to various situations of different amounts of wastewater replenishment, and can enable cold water to be discharged to the wastewater storage tank in time, reduce the temperature of wastewater, and be more conducive to production. Use the heating water heat exchange coil and the heating fan coil to realize heating in winter. Utilize waste heat more fully and more thoroughly.
