Latest Technology Air to Water Air Source Heat Pump Water Heater
heating and cooling for Hotel and Restaurant
ir source heat pump technology has been widely used all over the
world due to its high efficiency and energy saving benefits and
excellent working performance. The ultra-low temperature air source
heat pump unit adopts the international advanced jet enthalpy
increase technology to achieve the effect of "quasi-two-stage
compression", which is highly efficient and energy-saving.
High-efficiency heating and stable operation at ultra-low
temperature, the highest outlet water temperature can reach 60 ℃,
it is the model of coal-to-electricity projects in the northern
region. The ultra-low temperature air source heat pump unit for
coal-to-electricity conversion is efficient and stable. It is
widely used in the comfortable central air-conditioning system of
public facilities such as hotels, shopping malls, office buildings,
exhibition halls, airports, gymnasiums, etc., and can meet the
needs of electronics, pharmaceuticals, biological, light Different
use requirements of technological air-conditioning systems in
textile, chemical, metallurgical, pharmaceutical, electric power,
machinery and other industries.
2. Product features
1. Strong heating. The ultra-low temperature air source heat pump
unit can easily heat at -25°C. In severe cold conditions, the
heating capacity is increased by more than 20%, and the COP is
increased by more than 10%. The outlet water temperature of the
unit under heating conditions can reach 60℃, which can fully meet
the various heating methods at the load end. The traditional
heating method has been completely innovated, and the heating
problem in North China and East China has been effectively
improved.
The unit adopts the air supplement and enthalpy compressor, which
can realize quasi-two-stage compression, which not only ensures the
ultra-low temperature operation of the unit, but also greatly
improves the heating capacity of the unit and reaches the
energy-saving standard.
2. Intelligent defrosting. The unit adopts intelligent defrosting
technology, according to the temperature change rate of the surface
cooler, and at the same time considering the change of the external
environment temperature, it automatically corrects the conditions
for entering the defrost. It truly realizes "rapid defrost and
thorough defrost" to ensure normal heating operation.
3. Centralized building control
(1) The controller and electrical components adopt the
international advanced well-known brand wide temperature
configuration;
(2) The microcomputer controller can operate stably and reliably at
an ambient temperature of -25°C to 65°C;
(3) The microcomputer control system dynamically monitors the
operation of each unit, and can optionally be equipped with
RS485/RS-232 standard connection communication interface, built-in
Modbus communication protocol, realize network group control, and
ensure that the unit is in a better state of operation.
4. The system structure is stable and reliable Latest Technology
Air to Water Air Source Heat Pump Water Heater heating and cooling
for Hotel and Restaurant
(1) Adopting the international advanced EVI high-efficiency scroll
compressor, ultra-wide operating range, ultra-long operating life,
to ensure long-term stable operation of the unit. The
high-efficiency finned heat exchanger adopts high-efficiency
internally threaded copper tubes and sine wave-shaped aluminum
fins. The air distribution is evenly distributed, the air
resistance is small, and the heat exchange efficiency is high.
(2) The uniquely designed shell and tube heat exchanger has high
heat exchange efficiency, low water quality requirements, and is
easy to clean.
(3) The ultra-optimized pipeline structure adopts a "V" surface
cooler layout designed according to a better grace gradient, and a
heat pipe loop is preset at the bottom of the heat exchanger to
suppress ice by supercooling to ensure more thorough defrosting.
(4) High-strength frame structure with good stability. The panel is
made of high-quality galvanized steel plate, sprayed with epoxy
resin to prevent rust, beautiful appearance, and strong
anti-corrosion performance.
(5) The heating of the unit is more diversified, and the load end
can be radiators, fan coils, floor heating, etc.
5. Diversified heating methods
The diversified heating modes of the unit meet the requirements of
different users:
(1) Applicable to renovation projects in old urban areas. Such as:
teacher radiator renovation project that needs high temperature
water.
(2) Applicable to the new city heating project. Such as: household
floor heating (floor heating).
(3) Suitable for modern central air-conditioning system
engineering. Such as: water + fan-coil central air-conditioning
system, all-air central air-conditioning system
