The air-cooled heat pump is a component of a home central air-conditioning unit. In simple terms, the air-cooled heat pump works on the basis of a compression-type refrigeration cycle, which draws or discharges heat energy from the atmosphere through fans. Let's take a closer look at the working principle of the air-cooled heat pump. Hot Melt Adhesive For Protective Suit Hot melt adhesive can be used as a seam adhesive of protective clothing, while absorbing water vapor, blocking pollution sources, and overcoming the above existing problems of protective clothing.

The principle of air-cooled heat pump: air-cooled heat pump unit is the host of the air-conditioning system, because the use of air-cooled condenser does not require a cooling tower, while the evaporator is water-cooled, in the summer to provide cold water cooling, winter heating, provide hot water, fan The coil is the end device of the air-conditioning system. It is installed in the room as if the water is raised from a low position to a high position and a water pump is used. A heat pump can pump heat from a low temperature to a high temperature. So the heat pump is essentially a kind of heat lifting device. The function of the heat pump is to extract heat from the surrounding environment and pass it on to the heated object (the object with higher temperature). Its working principle is the same as that of the chiller. The air-cooled heat pump working against the Carnot cycle has a lower capacity than the air source heat pump. Its inlet and outlet water temperature is about 5 degrees Celsius (most of the company's setting parameters), and the temperature difference between the inlet and outlet water of the air source It reaches 40 degrees Celsius.
The air-cooled heat pump unit is used in conjunction with a fan coil. The former provides cold water or hot water, while the latter uses cold or hot water to exchange cool air or hot air. We can visualize the air-cooled heat pump unit as the brain of a central air-conditioner. If the brain is not working, the central air-conditioning system will lose all its functions and the system will stop operating.
With the gradual development of science and technology, we will be exposed to more and more new high-tech products. If we can understand the working principle of them, it will help us to use them better.
Hot melt pressure sensitive adhesive is a kind of pressure sensitive adhesive, the main components are rubber, resin and rubber oil, etc., need to be mixed and heated into a mushy object. This object is then applied to cotton cloth, tissue, and cotton paper and a kind of adhesive tape appears. The disadvantage of hot-melt pressure-sensitive adhesive is that the viscosity needs to be affected by temperature, and if the temperature is low, the bonding performance can not be achieved.
Advantages of medical protective clothing
1, medical protective clothing is an important part of medical protective Equipment, its basic requirements are to block viruses, bacteria and other harmful substances, so as to protect medical personnel in the diagnosis and treatment, care process is not infected.
2, medical protective clothing should also meet the normal use of functional requirements, with better wearing comfort and safety, such as good moisture permeability, flame retardant performance and alcohol corrosion resistance.
3, medical protective clothing with anti-penetration function, good air permeability, high strength and high hydrostatic water pressure characteristics, mainly used in industrial, electronic, medical, chemical and anti-bacterial infection and other environments.
High-performance protective clothing sealing hot melt adhesive has good air permeability and water absorption, can instantly absorb water beads, not only can bond non-woven fabrics, breathable film and other materials, seal the joint of the protective clothing, and when the protective clothing is damaged or pinhole cracks, it can quickly absorb water vapor, block the entry of external pollution sources, isolation, protection and adhesion. Such protective clothing effectively blocks the spread of the virus and ensures the health of medical staff!
