In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
high-temperature CO2Isolation ward exhaust system of air source heat pump, include air intake and the air outlet that is linked together with isolation ward, with supply fan, filter, gas cooler and intermediate heat exchanger have set gradually in the intake stack of air intake intercommunication, with fan, ultraviolet fluorescent lamp, evaporimeter and exhaust fan have set gradually in the air-out pipeline of air outlet intercommunication, intermediate heat exchanger is located the intake stack with the intersection of air-out pipeline the evaporimeter with position between the exhaust fan, the working medium exit linkage CO of evaporimeter2Compressor, said CO2The working medium outlet of the compressor is connected with the working medium inlet of the gas cooler, the working medium outlet of the gas cooler is connected with a throttle valve, and the working medium outlet of the throttle valve is connected with the working medium inlet of the evaporator.
A water outlet is arranged below the evaporator.
The intermediate heat exchanger is a total heat exchanger.
The filter is an activated carbon filter.
Compared with the prior art, the utility model beneficial effect be: high temperature CO2The air heat pump device is attached to the exhaust system of the negative pressure isolation ward, and the polluted gas is effectively treated while the exhaust system of the ward is perfected, so that the energy is saved, and the safety of medical personnel is better protected; compare traditional heating methods with the disinfection through heat pump heated air and can effectively the energy saving, utilize sensor and controller to realize the closed loop, can reach automatic control's purpose, when heat pump heating disinfection effect is not enough, open electric heater heated air automatically and effectively improve the disinfectionThe effect is achieved; CO22The air source heat pump has the same working principle as other air source heat pumps, and is a vapor compression heat pump, but the difference is that CO2The heat pump belongs to the supercritical cycle, namely CO at the condenser end2The heat pump system can not be condensed into liquid state, and the COP of the heat pump system is improved.
Drawings
Fig. 1 is a system diagram of the present invention.
Reference numerals: 1-supply fan, 2-filter, 3-throttle, 4-gas cooler, 5-CO2The system comprises a compressor, 6-an evaporator, 7-an intermediate heat exchanger, 8-an exhaust fan, 9-a water outlet, 10-an ultraviolet fluorescent lamp, 11-a fan, 12-an air inlet, 13-an air outlet and 14-an isolation ward.
Detailed Description
The invention will be further elucidated below on the basis of a specific embodiment.
High temperature CO as shown in FIG. 12An isolation ward exhaust system of an air source heat pump comprises an air inlet 12 and an air outlet 13 which are communicated with an isolation ward 14, wherein a fan 1, a filter 2, a gas cooler 4 and an intermediate heat exchanger 7 are sequentially arranged in an air inlet pipeline communicated with the air inlet 12, the intermediate heat exchanger 7 is a total heat exchanger, and the filter 2 is an activated carbon filter. A fan 11, an ultraviolet fluorescent lamp 10, an evaporator 6 and an exhaust fan 8 are sequentially arranged in an air outlet pipeline communicated with an air outlet 13, an intermediate heat exchanger 7 is positioned at the intersection of the air inlet pipeline and the air outlet pipeline and between the evaporator 6 and the exhaust fan 8, and a working medium outlet of the evaporator 6 is connected with CO2Compressor 5, CO2The working medium outlet of the compressor 5 is connected with the working medium inlet of the gas cooler 4, the working medium outlet of the gas cooler 4 is connected with the throttle valve 3, and the working medium outlet of the throttle valve 3 is connected with the working medium inlet of the evaporator 6. CO22Working medium in evaporator 6, CO2Circulating in the compressor 5, the gas cooler 4 and the throttle 3, constitutes CO2An air source heat pump. In order to discharge the condensed water of the heat pump system out of the air outlet pipeline, a water outlet 9 is arranged below the evaporator 6, and the condensed water flows out of the pipeline through the water outlet 9 and is collected and discharged by a water collecting tray and the like.
The working process of the utility model is as follows: fresh outdoor cold air enters an air inlet pipeline under the action of a fan 1, is filtered by a filter 2, passes through a total heat exchanger 7 and enters an isolation ward 14 through an air inlet 12.
