Cost-reducing, high-efficiency and energy-saving air source heat pump unit laboratory system

Abstract

The invention discloses a cost-reducing, high-efficiency and energy-saving air source heat pump unit laboratory system, which includes an experimental room, the experimental room includes a working condition machine room and a machine to be tested, a fan coil is installed in the working condition machine room, and the fan coil The pipe is connected to the energy storage water tank and forms a circulation loop with the energy storage water tank. The energy recovery circulation pump and valves are arranged on the circulation loop; the tested machine is connected with the tested machine water tank, and the tested machine water tank is connected with a proportional Type three-way valve, the other end of the proportional three-way valve is connected to the energy storage water tank, and the other end is connected to the energy storage water tank through the energy exchange circulation pump. The present invention recovers energy by adding an energy storage water tank, a fan coil unit, a proportional three-way valve, and a frequency conversion water pump. When energy exchange needs to be increased, the energy exchange can be increased by adjusting the frequency of the water pump and the proportional three-way valve; according to the fan The temperature difference between the coil and the room temperature can more finely control the energy exchange between the laboratory room and the energy storage tank.

Description

technical field [0001] The invention relates to all air source heat pump unit laboratories, in particular to a cost-reduced, high-efficiency and energy-saving air source heat pump unit laboratory system. Background technique [0002] The traditional air source heat pump laboratory uses an outdoor cooling tower to dissipate the heat generated in the laboratory to the air, which leads to high energy consumption, low efficiency, high operating cost and high cost during the test process. Due to the large number of equipment, maintenance is time-consuming And the high cost, coupled with more equipment, leads to loud noise. [0003] The air source heat pump laboratory needs to conduct unit heating test and unit cooling test. During this process, the laboratory will generate a lot of hot water and cold water. In the traditional laboratory, the hot water or cold water generated during the experiment will pass through the cooling tower. Distributed into the air without recycling, th...
