Electric energy storage high-precision air conditioning equipment using low-grade heat source heat pump

Abstract

The invention discloses electric energy storage high-precision air conditioning equipment using a low-grade heat source heat pump. A heating structure comprises a shell, an air inlet formed in one side surface of the shell, an impeller arranged in the shell, a motor, a control device, an airflow accelerating duct, an air outlet and a heating device, wherein the motor drives the impeller to rotate,the airflow accelerating duct accelerates airflow brought in by the impeller from the air inlet, the air outlet is formed in the other side surface of the shell and discharges the airflow passing through the airflow accelerating duct out of the shell, and the heating device is arranged at the air inlet in the inner side of the shell in an arc shape in the flowing direction of the airflow sucked in by the impeller and in the shell. According to the electric energy storage high-precision air conditioning equipment, an air curtain rejects the defects that the heating device is limited by the size of the air inlet, air inlet is obstructed, and the heating efficiency is low, and the good heating efficiency and the good air curtain discharging efficiency are achieved.

Description

technical field [0001] The invention relates to a heating and ventilation equipment, in particular to an electric energy storage high-precision air conditioning equipment using a low-grade heat source heat pump with an arc heater installed at an air inlet. Background technique [0002] The air curtain is a kind of HVAC equipment that forms an invisible air curtain through the powerful airflow generated by the centrifugal wind wheel, also known as air curtain machine, air curtain machine, air door, etc. [0003] The air curtain can be installed above or on the left and right sides of the entrance of shopping malls, theaters, hotels, restaurants, conference halls, cold storage, operating rooms and homes that require heat insulation, and separate the indoor and outdoor air by generating airflow curtains. To prevent the exchange of hot and cold air indoors and outdoors, the use of air curtains is not only convenient for access, but also has the effect of dustproof, anti-pollutio...

AI Technical Summary

Problems solved by technology

[0007] 1. Since the heater is set at the air outlet, the air flow from the acceleration air duct or the fan directly collides with the heater, and there is a great contradiction between the heating effect and the arrangement of the radiator fins of the heater: if the radiator fins are arranged relatively Close, the heat exchange effect is better, but the wind speed at the air outlet is low, and the effect of the air curtain cannot be achieved; on the contrary, if the heat sink is arranged sparsely, the wind speed effect is ideal, but the heat exchange effect is poor;

[0008] 2. Since the heater is set at the air outlet, the resistance of the heater to the airflow makes the distribution of the outflow airflow uneven, which greatly affects the efficiency of the heater;

[0009] 3. Moreover, due to the loss of airflow resistance caused by the heater, it is necessary to increase the flow rate and total pressure of the fan, so that the power consumption and noise of the air curtain will increase accordingly, and the volume and weight of the fan will increase accordingly, making installation difficult

[0013] 1. After adding a heater at the front end of the air inlet, the air inlet area is relatively reduced, and the air velocity of the air flow into the air curtain decreases, which affects the air velocity and work efficiency of the air outlet air of the air curtain;
