Split air conditioning unit is a kind of air conditioning system that installs the indoor unit and outdoor unit of the air conditioning system separately. The indoor unit is generally installed on the indoor wall or ceiling to blow cold (or hot) air into the indoor space. The outdoor unit is installed outdoors and is used for heat dissipation and cooling (or heating) cycles.
The split air conditioning unit is composed of an indoor unit, an outdoor unit, and copper pipes and cables connecting the two. The indoor unit transmits the refrigerant to the outdoor unit through a copper pipe, and the outdoor unit compresses the refrigerant and discharges the heat through the compressor, and then sends the refrigerant back to the indoor unit for circulation.
2. Air-cooled air circulation air conditioning units (large buildings, shopping malls, hotels, etc.).
The outdoor unit of the air-cooled air circulation** air conditioner cools or heats up the refrigerant in the refrigeration pipeline with the help of air flow, and sends the cooled or heated refrigerant to the indoor unit (air duct machine) through the pipeline, and the indoor unit sends the refrigerated (or heating) air into the air duct, and sends the refrigerated or heated air into each room or area through the air supply outlet (diffuser) in the air duct, so as to change the indoor temperature and achieve the effect of cooling or heating.
3. Multi-online air-conditioning units (apartment buildings, office buildings, hotels, etc.).
A multi-unit air conditioning unit is an air conditioning system that connects multiple indoor units with one outdoor unit. It can provide independent temperature control for multiple rooms or zones at the same time, and each indoor unit can set the temperature and wind speed individually.
The multi-connected air conditioning unit is composed of an indoor unit, an outdoor unit, copper pipes and electronic control parts connecting the two. The indoor unit transmits the refrigerant to the outdoor unit through copper pipes, and the outdoor unit compresses the refrigerant and discharges heat through the compressor, and then distributes the refrigerant to each indoor unit for circulation.
4. Air-cooled module unit
The air-cooled modular unit is based on modular technology, with air as the cold (heat) medium, as a cold (heat) source and integrated air conditioning equipment, it can be freely combined with air-cooled and hot water units, it can both refrigerate and heat, common 65kw, 130kw, 150kw, 210kw specifications of the unit.
5. Air-cooled water-cooled screw chillers (medium and large buildings, commercial centers, and factories).
An air-cooled screw chiller is a screw chiller that uses air cooling to dissipate heat. It does not require an additional cooling water system as compared to a water-cooled screw chiller, but rather dissipates heat into the surrounding air through a built-in fan, whereas a water-cooled screw unit requires an additional cooling water system that dissipates heat into the cooling water by water cooling.
Whether it is air-cooled or water-cooled, the working principle is the same, the refrigerant is compressed into a high-temperature and high-pressure gas through a screw compressor, then dissipated into liquid through the condenser, and finally depressurized into the evaporator through the expansion valve to absorb heat. The difference is that the condenser of an air-cooled screw chiller is air-cooled, dissipating heat into the surrounding air through a built-in fan instead of water cooling.
6. Centrifugal water-cooled chillers (large buildings, commercial centers).
Centrifugal chillers belong to steam compression refrigeration, which is mainly composed of:Centrifugal refrigeration compressor, evaporator, condenser, main motor, air extraction device, lubrication system, control cabinet and starting cabinet.
The principle of refrigeration is to apply energy to the refrigerant vapor through the compressor to increase the pressure and temperature, and then through the condensation and throttling process, it becomes low pressure, and the low-temperature refrigerant liquid evaporates into steam in the evaporator, and at the same time obtains heat from the surrounding environment (refrigerant, such as cold water) to reduce the temperature of the refrigerant, so as to achieve the purpose of refrigeration.
7. Ground source heat pump units (residential, commercial buildings, etc.).
A ground source heat pump unit is a kind of equipment that uses underground geothermal energy for air conditioning and heating. It provides heat and cold energy through underground geothermal energy, so as to achieve indoor temperature regulation.
In winter, when the underground temperature is higher than the indoor temperature, the ground source heat pump unit absorbs the heat energy through the groundwater or groundwater, and then transfers the heat energy to the room for heating. In summer, when the underground temperature is lower than the indoor temperature, the ground source heat pump unit releases heat energy through underground hot water or groundwater, so as to achieve indoor air conditioning.
8. Water source heat pump unit (especially suitable for buildings close to rivers and water).
A water source heat pump unit is a kind of equipment that uses the heat energy in the water body for air conditioning and heating. It provides heat and cold energy through the heat energy in the water body, so as to achieve the regulation of indoor temperature.
In winter, when the temperature of the water body is higher than the indoor temperature, the water source heat pump unit absorbs the heat energy through the water body, and then transfers the heat energy to the indoor heating. In summer, when the temperature of the water body is lower than the indoor temperature, the water source heat pump unit releases heat energy through the water body, so as to achieve indoor air conditioning.
9. Steam libr absorption chiller (industrial refrigeration, aerospace, etc.).
A steam LIBR absorption chiller is a device that uses steam and lithium bromide (Libr) solution for absorption refrigeration.
It vapor is exchanged with cold water through an evaporator to cool down the cold water, and at the same time the steam is cooled and condensed into water. The condensate is then heat exchanged with the lithium bromide solution through a condenser, so that the lithium bromide solution absorbs water to form a concentrated solution. The concentrated solution is heat exchanged with the steam again through the evaporator, so that the water in the lithium bromide solution evaporates out to form a dilute solution. The dilute solution is heat exchanged with cold water through a condenser to re-concentrate it and form a cycle.
10. Direct-fired LIBR absorption chiller
A direct-fired LIBR absorption chiller is a type of chiller that utilizes a direct-fired fuel such as:Natural gas, liquefied petroleum gasThermal energy, which absorbs water by lithium bromide (Libr) solution to achieve refrigeration equipment.
The working principle of direct-fired LIBR absorption chillers is similar to that of traditional LIBR absorption chillers, which is refrigerated by heat energy to drive lithium bromide solution to absorb water. However, direct-fired libr absorption chillers are usedDirect-fired fuel is used as a heat source, instead of traditional steam or electricity.
11. a hot water boiler
A hot water boiler is usually composed of a burner, a furnace, a heat exchanger, a water circulation system and a control system, etc., which produces high-temperature flue gas by burning fuel (such as natural gas, diesel, coal, etc.) through the burner, and then exchanges the flue gas with water through the furnace and heat exchanger. Once the water in the heat exchanger is heated, it is delivered through the water circulation system to the place where it needs to be heated, such as a heating system or hot water system** system.
12. a steam boiler
A steam boiler is a device that heats and converts water into steam, which is to produce high-temperature flue gas by burning fuel (such as natural gas, diesel, coal, etc.) through a burner, and then exchange the flue gas with water through the furnace and steam generator. After the water in the heat exchanger is heated, it is converted into steam, and it is transported to the place where steam is needed through the steam pipeline, such as heating equipment in industrial production processes, generator sets, etc.
