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.

This invention relates to a slot-type gas flow injection device including a high pressure cavity, an injection cavity the low pressure cavity, among which, one end of the injection device is connected with the high pressure cavity via a channel, the other end has an exhaust outlet, the high pressure cavity penetates high pressure gas to the inject cavity via the channel, a channel opening is set on the sidewall of inject cavity which is connected with a low pressure cavity via the channel, absorbs gas in the low cavity via the channel and exhausts gas via the outlet characterizing that the channel is composed of a rectangular slot and its connected wedge channel changing from narrow to wide speeds-up expansion after passing through them. The cross section of the infect cavity is rectangle.

A piezoelectric-electromagnetic combined energy gathering vibration damping device is arranged below a floor or a decking, and aims to gather the kinetic energy in the floor or decking and convert same into electric power for storage; the electric power can be released so as to form a damping effect, thus alleviating the floor or decking vibrations; the piezoelectric-electromagnetic combined energy gathering vibration damping device mainly comprises an inductance coil, a permanent magnet, a lithium ion battery, a particle damping container, a multi-grading electromagnetic particle damping, a piezoelectric ceramics, a loading plate, anchoring bolts, an insulation pad, and an electric quantity identification and control induction member; anchoring bolts are reserved on the loading plate and the piezoelectric ceramics; each member is placed in the loading plate according to required positions; the whole device is fixed below the floor or decking through the anchoring bolts. The piezoelectric-electromagnetic combined energy gathering vibration damping device can gather and utilize the energy of vibrations in the environment, and can effectively alleviate the floor or decking vibrations.

The invention provides a tight coupling ring rectangular hole gas nozzle atomizer capable of improving the atomization efficiency which comprises a liquid guide pipe and a lower body arranged on the outer surface of the liquid guide pipe in a sleeved mode; the atomizer comprises an upper body which is a hollow tube body structure and is sleeved outside the lower body, and a closed gas parking space capable of stabilizing the gas pressure is formed between the upper body and the lower body; the inner surface of the upper body end port is a conical surface or a conical-shape surface which is inclined towards the tail end of the liquid guide pipe; the outer surface of the lower body end port is in sealing contact with the conical surface or the conical-shape surface of the upper body througha corresponding cone shape surface, between the contact of lower body and the upper body; and a plurality of rectangular gas nozzles communicating with the outside and the gas parking space are uniformly arranged along the circumference. The rectangular channel can be a two-dimensional contraction type or two-dimensional contraction-expand (laval) type gas nozzle. According to the atomizer, the efficiency for the kinetic energy of the high-speed airflow on the relatively static liquid and liquid drops is improved, and the liquid and the liquid drops are atomized into finer liquid drops.
