Air source heat pump unit

Product overview

Air source triple heating water unit is the experience of the central air conditioning equipment design and manufacturing, based on the needs of users launched a hot water air conditioner. The unit adopts modular design, each module relatively independent units can be any combination of centralized control by the microcomputer; unit can change according to the load of air conditioning and water demand, through the start and stop the corresponding module unit to adjust its mode of operation, flexible control of cold (hot) and hot water output, to effectively save energy. Unit can be widely used in hotels, institutions, schools, factories, sauna, swimming pools, villas and other places.
Air source triple heating water machine combination is flexible and convenient, stable operation, sensitive, efficient and energy saving, has become the first choice of products in the air conditioning and water heater market.
System principle

Triple air source heating water unit is a kind of high efficiency and energy saving of air source heat pump system, the compressor, air conditioning water side heat exchanger, air side heat exchanger, hot water side heat exchanger, expansion valve, four way valve and other components. Unit has 5 kinds of functions, such as refrigeration, heating, hot water, refrigeration + hot water, hot water and hot water, in which the working principle of refrigeration and heating mode is the same as that of conventional air conditioning unit:
Heating mode: heat exchanger through the air side (evaporator), absorption air inexhaustible low grade heat, while using the compressor work, into high grade heat release to the hot water side heat exchanger (condenser), resulting in high temperature water.
Cooling mode: air conditioning in summer with hot water from the water side heat exchanger (evaporator) of frozen water absorbs heat through the compressor work will be transferred to the condenser heat hot water side heat exchanger in hot water, thereby achieving simultaneous cooling of air conditioning also produce high temperature hot water, the hot water production cost is zero.
Heating + hot water model: in the winter to provide hot water for life as a priority, when the hot water load demand to meet the unit will automatically switch to air conditioning heating mode.
Product features

High efficiency and energy saving
Set the noise of international famous brand, scroll compressor, low vibration and high energy efficiency ratio, the failure rate of less than 5 per thousand in overheating protection bottom of each compressor are installed with a suitable power electric heating.
The evaporator and the condenser adopt efficient threaded pipe, and the refrigerant distribution pipe bundle and optimize the design, has high efficiency of heat transfer of cooling and heating mode, the total heat transfer coefficient than the ordinary heat exchanger increased by 33%.
It can adapt to the relatively poor weather conditions, and can effectively reduce the film thickness and the heat resistance of water film, and increase the heat transfer efficiency of the coil.
Economic operation mode more energy efficient use of air conditioning in summer, can provide free hot water.
Operation of refrigeration + hot water mode optional "economy" mode of operation, the hot water by air conditioning condenser heat when heating, air conditioning compressor start and stop completely by the water temperature control, suitable for summer hot water load is relatively small.
Other seasons are also higher than other similar products of the energy efficiency ratio of hot water.
intelligent control
Due to the adoption of the modular design, the unit can be started in order to reduce the instantaneous impact on the grid, saving energy.
Boot time fast cooling, fast heating, according to the actual load at the start of the need to load the number of compressors to load, fast loading, shorten the waiting time of customers, improve the comfort of air conditioning.
Microcomputer controller can automatically sense the load size, and adjust the output of the corresponding module according to the fuzzy control theory to achieve the optimal matching between the unit output and the load to reduce the operating cost.
The unit is used for real-time monitoring and control of the high and low pressure, exhaust temperature and water temperature, and uses multiple system protection, which can ensure the safe operation of the unit in the best condition.
Each module has its independent structure, cooling system and the control and protection system, each module unit step way to achieve the required air-conditioning load capacity, in which any module failure does not affect the normal operation of other modules.
Condenser heat transfer to the water side heat exchanger in hot water, thereby achieving simultaneous cooling of air conditioning also produce high temperature hot water, the hot water production cost is zero.
Excellent quality
The key components of the refrigeration system are selected internationally renowned brand products, quality and stability.
The water heater adopts a shell and tube heat exchanger, the water side is not easy to scale or plug, and the water system is separated from water and electricity, and has no safety hidden danger.
Zero leakage pipeline connection, all pipes by welding connection, eliminate evase.
Strict air tightness and vacuum test, to ensure that the machine and parts without any leaks.
Strict corrosion resistance, durability and other testing, to ensure that any one unit is a high reliability products.
Multi use of one machine
Air source triple heating water unit is based on the air conditioning unit to increase the function of the water heater to achieve the perfect combination of air conditioning and water heater.
The hot water can completely replace the hot water boiler and save the investment of the hot water boiler, which is provided with the hot water of 50 degrees Celsius to 55 degrees.
A number of functions in one, the equipment is simplified, the project construction is simple, no need special room, occupied the construction area is small, the project investment is low.
Run quiet
The high efficiency and low speed axial fan with the principle of aerodynamic dynamics is adopted, and the noise is low.
More economical operation
