Building and closed space high-temperature sterilization and new coronavirus elimination heat pump air conditioning device and application thereof

Abstract

The invention discloses a building and closed space high-temperature sterilization and new coronavirus elimination heat pump air conditioning device and application thereof An air conditioning space is formed in a building or a closed space. The heat pump air conditioning device comprises a compressor, a high-temperature heat exchanger and an expansion machine. The temperature of high-temperatureand high-pressure gas output by the compressor reaches 100 DEG C or above so that bacteria and viruses carried in the high-temperature and high-pressure gas can be instantly killed. Sterile and non-toxic high-temperature and high-pressure gas sequentially passes through the high-temperature heat exchanger and the expansion machine to form sterile and non-toxic normal-pressure and low-temperature gas, and the sterile and non-toxic normal-pressure and low-temperature gas flows into the air conditioning space and exchanges heat with gas in the air conditioning space to form normal-temperature andnormal-pressure gas. The normal-temperature and normal-pressure gas flows into the compressor through an air return opening to be circulated next time, and therefore after multiple times of circulation, the heat pump air conditioning device can completely kill bacteria and viruses, especially new coronavirus COVID-19, in the air conditioning space, and the air conditioning space is purified intoa sterile and non-toxic space.

Description

technical field [0001] The invention relates to the field of air disinfection and purification space, in particular to a heat pump air-conditioning device for high-temperature sterilization of buildings and closed spaces and its application. Background technique [0002] Coronaviruses are a large class of viruses that widely exist in nature. The diameter of their virus particles is 60-120 nanometers, with an average diameter of 100 nanometers, and they are spherical or ellipsoidal. Common signs of patients infected with coronavirus include respiratory symptoms, fever, cough, shortness of breath and dyspnea. In more severe cases, infection can lead to pneumonia, severe acute respiratory syndrome, multi-organ failure, and even death. Health and epidemic prevention experts emphasize that the transmission routes of the new coronavirus that can be determined at present are mainly direct transmission, aerosol transmission and contact transmission, so people generally have demands...

Problems solved by technology

[0003] However, it is difficult to configure an effective air sterilization and disinfection system for existing heat pump air-conditioning devices. It is the concentration of the disinfection substance, or the intensity of the disinfection radiation, and the second is the contact (residence) time of the gas in the space of the sterilization and disinfection device

For example, one of the currently effective chemical disinfection and sterilization methods is the ozone process. In order to provide enough ozone per unit time, the power of the ozone generator must be large enough to achieve effective sterilization and disinfection. Enough contact ( The space volume of the equipment should be large enough, which is difficult to achieve in the dynamic process. At the same time,
