Protective clothing air conditioning unit

Abstract

The protective clothing air conditioning unit comprises a ventilation waistband, an air conveying hose and an air conditioner body, and the air conditioner body is worn on the back waist of a user through the ventilation waistband; the air conditioner body provides cold air or warm air meeting the biological safety requirement for the interior of the protective suit through the air conveying hose. The air conditioner body adopts the design of the cross-flow fan and the semiconductor chilling plate, and efficient supply of cold air or warm air meeting the biological safety requirement is achieved through reasonable air opening design and internal flow guide layout. The ventilation waistband enables cold air or warm air to penetrate through the waistband and enter the lower half body of the protective suit. The air conditioning unit designed by the invention can provide a comfortable internal environment meeting the biological safety requirement for the protective clothing; the air conditioner body is compact in structure and reasonable in layout design, the air conditioner body is of the design structure that air enters from the outer side and / or the bottom and exhausts from the upper portion, air suction and air exhaust are independent of each other and do not affect each other, and the unit size is effectively reduced while the refrigerating or heating efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, in particular to an air conditioner unit for protective clothing. Background technique [0002] In the fields of medical and health care, animal husbandry and veterinary medicine, when dealing with major infectious disease outbreaks, it is often necessary to wear a full set of conjoined protective equipment to protect the staff from contamination or infection by pathogens. Due to the poor air permeability and thermal conductivity of the protective clothing, the wearer feels hot and uncomfortable; especially at a higher ambient temperature, the wearer will sweat profusely and suffer. In the prior art, there is also a technical solution of using semiconductor refrigeration chips to provide cold air for protective clothing, but there are still the following disadvantages: 1. The air flow in the protective clothing is not smooth, resulting in poor cooling effect on the lower waist of the bod...

Due to the poor air permeability and thermal conductivity of protective clothing, the wearer feels hot and uncomfortable; especially at a higher ambient temperature, the wearer will sweat profusely and suffer

In the prior art, there is also a technical solution of using semiconductor refrigeration chips to provide cold air for protective clothing, but there are still the following disadvantages: 1. The air flow in the protective clothing is not smooth, resulting in poor cooling effect at the lower waist of the body, and the air flow above the waist is blocked 2. The preparation and diversion design of the cold air and hot air of the refrigeration main engine is not reasonable enough, resulting in large volume and low refrigeration efficiency; 3. The emergency of power failure or machine failure of the refrigeration air supply system is not considered Protection, the battery pack does not achieve continuous one use and one standby to adapt to long-term work
