A volt-free boiler thermostat, also known as voltage-free boiler thermostat or dry contact boiler thermostat, offers a flexible and safe solution for smart home heating systems.  This fundamental difference brings several advantages.

1. No voltage supplied by thermostat. One of the key benefits of no voltage output. Since the thermostat output terminals do not pass voltage, the risk of damage to the boiler control board due to voltage incompatibility is reduced. And since gas boilers are often installed in humid environments such as basements, the thermostat's voltage-free output design also provides additional safety.

2. Compatibility and flexibility. Because the thermostat contacts are dry contact, they can be used with a wide range of heating control systems and smart home integration and retrofitting heating thermostat.

3. Electrical isolation. Volt free contacts electrically isolate thermostat from boiler’s power supply, which can improve safe heating control and reduce electrical interference or noise affecting the thermostat operation.

4. Simplified wiring and installation. Volt free thermostats typically require fewer wiring considerations related voltage matching. Unlike conventional thermostats that send voltage to operate the boiler, volt-free digital thermostats function purely as a switch—opening or closing the circuit without supplying -any voltage. This design helps simplify both installation and fault diagnosis.

In some projects, customers may ask, "Why are there drops from the air conditioner?" Are there any problems? Actually, it's not a problem but a good sign of air conditioner operation.

This article will explain this phenomenon thoroughly from the perspectives of mechanism, structure design, and the engineering applications.

 

I. The essence of condensation: the water "squeezed" from the air

 

There always exists steam (humidity) in the air. When the air conditioner is cooling, the surface temperature of the evaporator is lower than the dew point of air. As a result, the steam converts from an air state into a liquid state when it meets coolness, attaches to the fins of the evaporator, and finally unites to form drops. That's what we see: the condensation drops.

 

This is the same as the water on the surface of a glass of cold Coca-Cola in the summer.

 

II. Key mechanism: Dew point

 

The key for air conditioners to produce condensation is a physical concept: dew point.

When the ambient temperature is 30℃ with a humidity of 70%, the dew point at this time may lie at 24℃. The evaporator surface temperature is normally 5 to 12℃, which is further lower than the dew point, and the condensation is a must.

 

III. How does the air conditioning system deal with condensation water?

 

In the air conditioners, condensation does not come out freely; instead, it is connected, led, and expelled through a complete design.

 

1. Drainage tray

The drainage tray, located directly below the evaporator and made with corrosion-proof materials, features a sliding angle design that ensures water flows to the outlet. For some high-end models, the tray will be sprayed with antibacterial painting to avoid mildew and with a double-layer structure to avoid secondary condensation.

 

2. Drainage pipe

It is the natural method for drainage. Relying on gravity and a slope (≥1°), the condensation flows to the outlet naturally. It is economic and stable

 

3. Condensate pump

For the occasions in which the natural drainage pipe can not work, a built-in condensate pump is necessary. It is commonly used in ceiling cassette air conditioners, ducted air conditioners, and some commercial spaces. It helps to absorb the water in the corner or at a low level, pump it up to a higher level or through a distance, and exhaust it finally.

 

 

IV. When is "dripping" normal?

 

The following occasions are normal in our daily life:

High-humidity areas (Southeast Asia, Coastal regions, rainy season, etc.);

The first start-up of the air conditioner.

Crowded spaces (hotels, conference rooms, shopping malls, etc.).

Frequent opening of doors and windows.

 

The more the condensate, the better the dehumidification ability of the air conditioner.

 

V. When is "dripping" abnormal?

 

Be aware of those occasions:

Direct drops from the indoor unit;

Water seepage in the wall;

Water leakage of the ceiling cassette air conditioner.

 

Common reasons:

Clogged drain pipe,

Insufficient drain slope,

Improper installation,

Drain pump malfunction,

Evaporator thawing after freezing.

 

Returning to the initial question: Why do air conditioners produce condensation? The answer is actually quite simple—it's because they're working effectively. Condensation is essentially the air conditioner performing two core tasks: cooling and dehumidifying. In high-humidity environments, condensation can even serve as a "visual indicator": more water indicates stronger dehumidification capabilities.

However, for engineering projects and B2B clients, another crucial aspect is condensation management. Condensation itself isn't the problem; uncontrolled condensation is. A good air conditioner not only needs to cool but also needs to "manage water."

The compatibility of cosmetic packaging and its contents broadly refers to the interaction between plastic packaging and cosmetics, including chemical compatibility, physical compatibility, and biological compatibility.

The following briefly describes the specific situations of various types of incompatibilities:

Chemical incompatibility: The chemical components of the packaging materials, chemical reactions between the decomposed products and cosmetic ingredients during processing, have an adverse effect on the cosmetics or packaging materials; chemical incompatibility manifests as changes in the appearance and smell of the packaging materials or cosmetics For example: yellowing of material, yellowing of pink packaging material

Biological incompatibility: certain substances in packaging materials migrate to cosmetics, which has an adverse effect on users; manifested in the amount of harmful substances dissolving exceeds the amount specified in the relevant cosmetic hygiene standards or specifications in the country where the cosmetics are sold; generally, Harmful substances include various plastic additives, residual solvents, volatile organic compounds, and harmful metal elements. Of course, not all dissolved plastic additives will have a serious impact on the properties of cosmetics. When the dissolved component is one of the cosmetic components, the amount of the dissolved component is small, and the dissolved component is not harmful to the user. This dissolution phenomenon is normal. Compatible. For example: The colorant in the plastic is precipitated into the content. The content is originally off-white.

Physical incompatibility: The physical changes of the packaging material and the contents due to the influence of each other; physical incompatibility manifested as penetration, adsorption, cracking, cracking, dissolution, etc. In the test and judgment, physical incompatibility is often misjudged as chemical incompatibility. This is because the phenomenon of physical incompatibility is more obvious and the reaction is more violent. For example: surface crack, stress crack

In view of the fact that the plastics used in cosmetic packaging materials have certain solvent resistance properties, and the cosmetics are relatively mild, the incompatibility between cosmetics and packaging materials is more manifested as physical incompatibility.

In addition, quantitative chemical analysis experiments have proved that the incompatibility between cosmetic packaging materials and their contents is usually not a single manifestation.

One hundred years ago, the American chemist Baekeland inadvertently manufactured plastic during the experiment. This waterproof and heat-resistant material quickly became the fastest-growing material in the industrial field, replacing metal in many aspects. , Wood, cement and glass and other traditional materials. It can even be said that plastic has constructed a modern society.

However, the rapid growth of plastic production also brings a series of problems. This non-degradable material is thrown into the natural environment. Animals eat it as food, and starve to death because they cannot digest a large amount of plastic. At the same time, a large amount of plastic has caused great pollution to the environment, and eventually returned to people's dining tables along the food chain, harming humans themselves.

In 1972, the United Nations convened the United Nations Conference on the Human Environment in Sweden. The conference passed the "Declaration of the Human Environment" and put forward the slogan "Protecting and improving the environment for this and future generations", and set June 5th each year as " World Environment Day". This is the first conference in human history to study the protection of the human environment worldwide. Since then, the term "environmental protection" has attracted the attention of all countries and people around the world. After entering the 21st century, environmental protection has become a trend and trend. All walks of life are constantly developing new products in the direction of environmental protection to promote their own sustainable development.

In the cosmetics industry, brand manufacturers should avoid complicated packaging as much as possible and choose some sustainable and recyclable materials as packaging materials. As a company specializing in the production of cosmetic packaging, Guangzhou LISSON Plastic Co., Ltd. has been following the trend of the times, keeping up with the world's environmental protection trend, and adhering to the concept of environmental protection. It has launched a series of environmentally friendly green packaging, such as paper-plastic tubes, sugarcane tubes, Aluminum tubes and PCR tubes, etc.

The paper-plastic tube is a sheet tube made of composite materials. The sheet tube usually has three or five layers, each layer in order to better realize the isolation and protection of the product itself. The production of paper-plastic tubes is actually in the production process, replacing one layer of plastic with more environmentally friendly cardboard. This method can reduce the plastic content of the tube by 30%-45%, which in turn reduces the packaging of cosmetics. The carbon footprint has further promoted the sustainability of cosmetic packaging.

Guangzhou LISSON Plastic Co., Ltd. has been working in the cosmetic packaging industry for many years. So far, it has more than 1,000 cosmetic tubes and more than 40 patents. It has accumulated a wealth of cosmetic tube tube types, specifications, capacities, designs, etc. Experience, can provide one-stop service from design, proofing, filling, production to packaging, to maximize the convenience of customers.
