In HVAC, the difference between an air conditioning unit and a fresh air unit is almost the same whe

The difference between the fresh air unit and the air conditioning unit is one: the fresh air unit is used to deal with the fresh air, in a large building, the general fresh air unit is used in conjunction with the fan coil unit, and the fan coil unit + fresh fan is actually similar to the air conditioner. Under normal circumstances, the air conditioner itself has a fresh air outlet, which is used to ensure the quality of indoor air and supplement the indoor exhaust air.

Since the fan coil unit does not have a fresh air outlet, it needs to be provided by the fresh air fan, and the treated fresh air provided by the fresh air unit and the return air treated by the fan coil unit are either mixed first and then processed by the fan coil unit, and then sent into the room.

The difference between the fresh air unit and the air conditioning unit is two: the fresh air unit mainly treats the outdoor air, while the air conditioning unit is used to process the air treated by the fresh air fan, but the fresh air fan can have return air, and the return air can also have fresh air, the purpose of which is to better adjust the temperature and humidity and other parameters.

The difference between the fresh air unit and the air conditioning unit is three: the fresh air unit generally does not bear the heat and humidity load of the air conditioning area, and the main function is to send fresh air, of course, the ideal state is that the temperature and humidity of the air supply are constant, so the fresh air unit generally controls the temperature and humidity of the air supply.

The fourth difference between the fresh air unit and the air-conditioning unit: the air-conditioning unit loads the heat and humidity load in the air-conditioning area, which plays a comprehensive role in the air conditioning area and ensures a certain fresh air volume. Air conditioning units are usually mainly used to control the temperature, humidity and air quality of the air-conditioned area, and the air treatment process is generally complex.

The fifth difference between fresh air unit and air conditioning unit: the air conditioning unit is relatively complex in terms of process compared with the fresh air unit, so the air conditioning unit is mostly used in a large public area where the fan coil unit cannot be installed, while the fresh air unit is mostly used in a small area with a fan coil unit installed.

Whether it is an air-conditioning unit or a fresh air unit, the use and installation are more common, the fresh air unit and the air-conditioning unit are different, but they can complement each other, Comfort 100 recommends that you install the fresh air unit at the same time, and then install the fan coil unit separately in each room, so that you can learn from each other's strengths, and at the same time can achieve the purpose of more energy-saving and comfortable.

Yes upstairs and upstairs upstairs is quite right. The fresh air unit only operates under the condition of fresh air and treats 100% of the fresh air.

Compared with the fresh air unit, the air unit has more air treatment capacity under the return air condition. That is, 100% of the fresh air can be processed, and the primary return air or even the secondary return air can be processed.

In the answer on the second floor, the fresh air unit plus the mixed air section becomes the air conditioning unit, and it should be noted that after adding the mixed air section, the selection calculation of the heating and refrigeration equipment inside also needs to be calculated according to the return air condition.

ps: Hope it helps you!!

The difference between the air-conditioning unit and the fresh air unit in HVAC is mainly that the operating conditions of the unit are different, the air-conditioning unit is designed to operate under the return air condition, and the fresh air unit is designed to operate under the fresh air condition.

Hello dear! Glad to answer for you: The differences between air-cooled heat pump units and air conditioning units are as follows.

1. Air-cooled hot pump is a kind of air-conditioning unit in the air-conditioning industry that is different from the air-cooled chiller of the car balance. In addition to the function of producing cold water from the air-cooled chiller, the air-cooled heat pump unit can also switch to the heating condition to produce hot water. The principle of air-cooled heat pump is based on compression refrigeration cycle, using refrigerant as the carrier, through the forced heat exchange of the fan, absorbing heat from the atmosphere or discharging heat to meet the demand of cooling or heating.

2. The conditioning unit can carry out a number of treatments for indoor air, for example, it can mix, filter, cool, heat, humidify and other different functions of air closure and rent, and the combined air conditioning unit can be widely used in comfortable air conditioning, process air treatment and large and medium-sized purified air conditioning systems.

Summary. Hello, the difference between air-cooled heat pump unit and air conditioning unit is that they work differently and application scenarios. An air-cooled heat pump unit is a heat pump system that uses air as a heat or cold source, which can transfer the heat from the outdoor air to the interior for heating or cooling.

Its advantages are energy saving and environmental protection, easy installation, long service life, etc. It is suitable for all kinds of buildings such as residential, commercial office buildings, hotels, etc.

Hello, the difference between air-cooled heat pump unit and air conditioning unit is that they work differently and application scenarios. Air-cooled heat pump unit is a kind of heat imaginary pump system that uses air as a heat source or cold source, which can transfer the heat in the air outside the room to the room to achieve heating or cooling. Its advantages are energy saving and environmental protection, easy installation, long service life, etc.

It is suitable for all kinds of buildings such as residential, commercial office buildings, hotels, etc.

An air conditioning unit is a device dedicated to refrigeration, which compresses the refrigerant to absorb heat from the room and then expel the heat from the outside to achieve cooling. Its advantages are good refrigeration effect and high control accuracy. It is suitable for places where strict temperature control is required, such as laboratories, operating rooms, etc.

In addition to the above differences, air-cooled heat pump units can also be used for heating, while air conditioning units can only be used for cooling. In addition, the cost of installation and maintenance of air-cooled heat pump units is relatively low, while the maintenance cost of air-conditioning units is higher.

In short, the difference between air-cooled heat pump units and air-conditioning units is that their working principles and application scenarios are different.

The air conditioning unit can be used to heat the bar.

It seems like you're wrong.

This kind of unit is not possible.

Not your average air conditioner.

Combined air conditioning units.

It can be connected to hot and cold water pipes.

It can be cooled or heated.

The home version is the same.

The one you're talking about now can be cooled and heated.

Hello dear, there are the following differences between air-cooled heat pump unit and air-conditioned unit: First of all, air-cooled heat pump unit and air-conditioning unit are the main application equipment of energy-saving technology, and their main difference lies in the power reproduction technology. The air-cooled heat pump unit reuses the heat from the outside air temperature to the room at a lower temperature, so as to maximize energy saving.

It uses a pump heat pump to feed the outdoor low-temperature heat evaporation separator to the condenser, focusing the outdoor heat into the room, so as to achieve heat reuse. The air conditioning unit is different from the air-cooled heat pump unit, which is a traditional heating system equipment, and its main function is to reuse the outside temperature to the room at a lower temperature. The air conditioning unit can evaporate the outdoor heat into the room through the condenser, thereby lowering the indoor temperature and maintaining the indoor temperature within the expected temperature range.

In short, the main difference between the liquid transportation of air-cooled heat pump units and air-conditioning units is the reproduction technology and the temperature of re-employment of buried land. Air-cooled heat pump units can maximize energy savings, while air conditioning units can adjust the room temperature to maintain a specific temperature range.

These terms are not all accurate equipment terms, and some are colloquial.

The air-conditioning box and air-conditioning unit cover a wide range: the air-conditioning unit is often said to be a larger equipment, and the air-conditioning box includes both large and small.

Air handling units and air conditioning units are often a concept.

The air-conditioning unit is divided into a combination of various functional sections and an integrated one from the equipment form. Usually the large ones are combined, and the one-piece ones are mainly small. Modular air conditioning units are also flexible and can be combined into a variety of air handling segments.

The air conditioning unit is divided into fresh air units that only deal with fresh air, air conditioning units that deal with the mixture of fresh air and return air, and air conditioning units can also only deal with return air.

The working principle is to use cold water to cool down and dehumidify. The difference is that the fresh air unit deals with fresh air, and the temperature and humidity are higher, while the air conditioning unit deals with the mixed air, and the temperature and humidity are closer to the air supply state, so the area and number of coils of the two units are different.

From the perspective of application occasions, combined, air-conditioning units and air-conditioning boxes are selected according to the size of the air volume; According to the air processed, fresh air units are used to treat fresh air and air conditioning units used to mix air.

The air conditioning unit mainly considers the cooling load of the room, while the fresh air unit mainly considers the air supply volume, which is completely different. The design of the air conditioning unit mainly considers the heat of the heating equipment in the room, how much heat is dissipated by the human body, how much heat is transferred from the exterior wall and other heat sources, while the design of the fresh air unit considers how many people are inside, what is the place to do, and what is the amount of fresh air that each person needs.

An air conditioning unit is a unit that can process cold and hot air, and then send cold and hot air to the room as needed. The fresh air unit is sent indoors, and the natural air introduced from the outside is filtered, and the equipment that is sent into the room is called a fresh air unit. Of course, there must be an indoor exhaust mechanism so that the air can circulate and circulate.

Different working conditions, different uses, different costs, etc.

The fresh air unit is a device that directly introduces the outdoor air into the room after filtration, temperature and humidity, and the use of the fresh air unit can keep the indoor air pressure higher than that of the outdoors, and it is always in a positive pressure state, which is mainly used in some special places or places with high requirements for fresh air volume; Since the fresh air unit directly treats the outdoor high-temperature air, the selection of key components of the air conditioner such as evaporator, condenser, and compressor will be relatively large, and the relative product cost is higher, and the price is more expensive.

The ordinary comfort air conditioning unit is to cycle the indoor air for many times, relatively speaking, the requirements for air filtration and temperature regulation will be much lower, because the air quality of the closed indoor air with multiple cycles will be much better, the temperature of the indoor air will gradually decrease, and the heat exchange load of the air conditioner will gradually decrease.

When using ordinary comfort air conditioners, it is required to close the doors and windows, and open the doors and windows regularly for ventilation.

Fresh air unit refers to the unit where the circulating air is all outdoor fresh air; The fresh air conditioning unit usually refers to the unit that can achieve a partial proportion of fresh air return air.

The functions that can be achieved by these two types of units are quite different, which also determines the different design and selection of key components of the refrigeration system, different control logics, different working ranges, and different application places.
