A wide temperature zone multi-mode water supply device

Abstract

The invention provides a multi-mode circulating water supply device. The device comprises an expansion heat exchanger, a first water pump, a second water pump, a first adjusting valve, a second adjusting valve, a first temperature sensor, a second temperature sensor, a first flow sensor, a second flow sensor, a first proportional distribution valve, a second proportional distribution valve and a heat pump; and the device uses a heat pump technology for realizing the energy compensation, saves water to achieve recycling to prevent wastes of water resources, adopts the expansion heat exchanger to reduce environmental heat exchange loads, and synchronously realizes water supply, pressure fixation and exhausting of system gas or excessive water. The device is flexible, convenient, compact in structure, water-saved, environment-friendly and energy-saved, can realize constant-temperature and constant-flow water supply in different temperature areas under different heat loads, and is widely suitable for the water supply demands of different laboratories with different temperature areas and loads and other water use places.

Description

technical field [0001] The invention relates to a wide temperature zone multi-mode water supply device, in particular to a heat pump-based wide temperature zone multi-mode circulating water supply device for laboratories. Background technique [0002] When performing water-requiring operations in the laboratory, upper and lower water configurations are required. At present, tap water is often used as a cooling medium, and tap water is directly discharged into the sewer through pipelines after use. If heat source water is required, a separate heating device is often required. This method of operation has at least the following disadvantages: it is necessary to configure the upper and lower water in the laboratory, which increases costs and potential safety hazards; it is necessary to install the experimental device near a place with upper and lower water channels, which is inconvenient to operate; Great waste of water resources; direct discharge of cold and heat sources cau...

This method of operation has at least the following disadvantages: it is necessary to configure the upper and lower water in the laboratory, which increases costs and hidden safety hazards; it is necessary to install the experimental device near a place with upper and lower water channels, which is inconvenient to operate; Great waste of water resources; direct discharge of cold and heat sources causes great energy waste and environmental heat pollution

[0003] At present, the shortage of laboratory space and the aging of equipment are common phenomena in colleges and universities. Even if the laboratory is recycled and public arrangements are becoming very crowded, the relevant water and sewage facilities are unsustainable, which has become a luxury.
