New Energy Air Source Heat Pump For Air Conditioning System
Purpose
The low-ambient-temperature air-source heat pump (cold water) unit is the integrated central air-conditioning equipment with air as the cold (heat) source and water as the cooling (thermal) medium to serve as dual-purpose (cold and heat sources) equipment. With the advantages of high efficiency, low noise, reasonable structure, simple operation, safe operation, and convenient installation and maintenance, the unit is widely used in comfortable central air-conditioning systems of public facilities such as hotels, shopping malls, office buildings, exhibition halls, airports and gyms, and can meet different requirements of process air-conditioning systems in electronics, pharmacy, biology, light textile, chemical industry, metallurgy, power, machinery and other industries.
Principles
When the unit operates in the cooling (heating) mode, the compressor absorbs the refrigerant on the low-pressure side, compresses the refrigerant into high-temperature and high-pressure refrigerant, and discharges it to the condenser. The heat released in the condenser enables the refrigerant to become high-pressure liquid refrigerant, this kind of liquid refrigerant becomes low-pressure mist after throttling, enters the evaporator for heat exchange, and then it becomes gaseous and enters the compressor. Meanwhile, the refrigerant exchanges heat with the water on the utilization side so as to lower (raise) the water temperature, thus achieving the purpose of cooling (heating).
The low-ambient-temperature air-source heat pump (cold water) units are divided into single-heat type and heat pump type. The heat pump unit integrates the functions of cooling and heating, and can realize cooling in summer and heating in winter, hence one unit with multiple functions.
The low-ambient-temperature air-source heat pump (cold water) unit features intelligent defrosting, and realizes timely and thorough defrosting, thus avoiding heat loss. In the meantime, it can perform many other automatic control functions in addition to intelligent defrosting, such as energy management, anti-freezing monitoring and operation mode, to ensure the efficient operation of the unit.
Product features
★ The modular unit can be composed of several unit modules. The unit module equipped with the hand controller is the main module, and the sign of small hand is attached on the board of the electric control box. Other unit modules are sub-modules, and are not interchangeable with the main module, but interchangeable with each other.
★ Adaptability of wide climatic zone
The normal temperature unit can operate safely in the ambient temperature range of -15℃ ~ +43℃ with the highest effluent temperature up to 60℃, and the ultra-low temperature unit can operate safely in the ambient temperature range of -30℃ ~ +43℃ with the highest effluent temperature up to 60℃.
Product featuresHigh efficiency and energy saving
Kinflare low-ambient-temperature air-source heat pump series units have reached and surpassed the national energy-saving standard according to the testing by the national authoritative testing organization.
In addition, the whole unit is configured with air cooling mode without large external equipment such as boilers and cooling towers, thus reducing the initial investment and operating cost of users. It has the advantages of safety and environmental protection in addition to energy saving and high efficiency.
Environmental protection
R410A environment-friendly refrigerant is used in the unit and does not contain the chlorine element that damages the ozone layer. This kind of refrigerant is stable and non-toxic, and causes cold destruction to the ozone layer (ODP is 0). In addition to the advantages of environmental protection and no substitution risk, the refrigerant is also characterized by high heat transfer coefficient, and this can facilitate the improvement of the low-temperature heating capacity of the unit and reduction of the operation energy consumption. Kinflare low-ambient-temperature air-source heat pump series units comply with the national policies of energy conservation and emission reduction, reducing the emission of waste gas and dust, and the haze days.
