3 Product characteristics
The direct heating circulating air to water heat pump water heater uses an advanced waterway automatic-
control system. After entering the unit, cold water is heated to 55°C, and directly enters the heat accumulation
tank to be used by the user. In addition, when the water temperature drops in the tank, cyclic insulation can be
implemented automatically to ensure hot water temperature in it. The unit operates at all weather conditions all
year around in the range from -26°C to 46°C. It is widely applicable for various sites that require domestic water

with three kinds of heating capacity are available: 31kW, 40kW, and 60kW. The modular unit combines 1 to 16
same or different unit modules to form series products with the heating capacity in the range from 31kW to
960kW and meet different engineering requirements.
ƇHigh outlet water temperature
The advanced waterway control system is used, and the outlet water temperature is high. The factory
setting is 55°C, but the maximum outlet water temperature can reach 70°C.
ƇHot water is generated rapidly and supplied upon start-up
The direct heating design ensures that cold water is immediately heated to the usable temperature after
entering the system. Hot water is supplied upon start-up. The hot water output is large and the speed is high.
ƇHigh EER
The EER is high.The average EER is above 4.0 and the maximum value is 5.8. At the same energy
consumption, the hot water output far surpasses that of other water heating devices.
ƇSafe and reliable operating
A heat pump is used to produce hot water for life. Different from the mode that electricity or fuel is used to
directly heat water, this mode eliminates dangers of traditional water heaters such as flammability, explosiveness,
gas poisoning, and electric shock. The cutting-edge microcomputer control system provides complete protection
functions and eradicates the hidden safety hazards such as leakage of electricity, dry burning, and ultra-high
temperature. After repeated researches and tests by experts, the optimized design features a compact and
pleasant structure, simple and convenient control, safe and reliable performance, and leading EER in the world.
All the key parts are supplied by renowned manufacturers in the world. By virtue of elaborate processing of
C&H, every unit has passed a strict performance test before delivery to ensure that it FDQRSHUDWHVWDEO\DQG

ƇSimple and convenient control
The unattended microcomputer system implements automatic control. The user-friendly English man-
machine interface enables the user to know the system status at a glance. With the multi-module and network-
based control, a system can control as many as 16 master units, and implement convenient and fast control.
The user can press the button to get hot water.
ƇFlexible installation
The compact and small size of the unit facilitates transportation. A special equipment room is not required,

pipeline system makes maintenance easy and convenient, applicable to all kinds of projects.
ƇEnvironmental protection
The heat pump technology of reverse Carnot cycle is used to absorb heat in the air to heat water for life. No
gas is discharged during the operation, so the unit is a green environmental-protection product. This heating
mode is different from mineral fuel such as coal, oil, or gas that contaminates the environment in the burning
process.

Heat Pump Water Heater
QSPEVDU
6 Operating principle
Air-source heat pump water heater is based on Inverse Kano circulation principle, driven by a small amount
of electrical power, with refrigerant as carrier, continuously absorbs low grade heat (-26~46°C) in the air, and
transforms them into usable high grade heat, which is then released into water so as to generate and secure
domestic hot water (with default temperature of 55°C, and 70°C at most), and finally transports hot water
through hot water pipes to users.

ƇSystem composition
The air source central hot water system generally comprises the air source heat pump water heater and the
heat insulating water tank, and the auxiliary devices such as the connected pipeline, water pump, and valve as
well.
The air source heat pump water heater consists of main parts such as the compressor, water side heat
exchanger, air side heat exchanger, throttling device, electronic hot water valve, liquid receiver, and gas liquid
separator.
Ƈ 'LUHFWKHDWLQJÀRZ
When the water level switch is at a low level, the unit is powered on to start. The pressure pump starts
and the water makeup valve is turned on. The high temperature and high pressure refrigerant gas discharged
from the compressor enters the tube in tube heat exchanger, and exchanges heat with tap water replenished
from the direct heating water inlet to heat water. After passing the electronic expansion valve for throttling,
the condensate refrigerant enters the evaporator to absorb heat and evaporate. The refrigerant returns to the
compressor from the gas liquid separator to implement the next cycle.
Ƈ &\FOLFLQVXODWLRQÀRZ
When the water level switch is at a high water level or drops from a high water level to a middle water
level and the temperature of the temperature sensor of water tank is lower than the set temperature, the cyclic
insulation function starts. The recycle pump starts and the recycle valve is opened. The high temperature
and high pressure refrigerant gas discharged from the compressor enters the tube in tube heat exchanger,
and exchanges heat with hot water withdrawn by the cyclic loop. After passing the electronic expansion valve
for throttling, the condensate refrigerant enters the evaporator to absorb heat and evaporate. The refrigerant
returns to the compressor from the gas liquid separator to implement the next cycle.

gas discharged from the compressor is reversed, and then directly enters the evaporator for heat exchange and
defrosting. The defrosted and condensate refrigerant passes the electronic expansion valve, and enters the
tube in tube heat exchanger, and exchanges heat with hot water withdrawn by the cyclic loop to evaporate. The
gas is re-taken in the compressor to perform the next cycle.

shuts down.
High/Low pressure switch: It detects high pressure and low pressure of the system. To protect the unit from
operating in an abnormal status, malfunction is displayed when high pressure of the system is higher than the
set value or low pressure is lower than the set value. The unit is not started up or shuts down.
Ambient temperature: It is used to control operating range of water heating. The ambient temperature range
is from -26°C to 46°C during water heating. Beyond this range, the unit cannot operate in the water heating
mode. The function also joins other related control, for example, control on gear shifting of fan.
Water pipeline temperature detection: The inlet water temperature sensor and outlet water temperature
sensor are provided. The corresponding algorithm adjustment is performed for opening of the electronic hot
water valve according to the temperature detected by the outlet water temperature sensor.
Refrigerant pipeline temperature detection: Refrigerant pipeline temperature detection covers the discharge
temperature sensor, outlet pipe temperature sensor, and inlet pipe temperature sensor. The discharge
temperature sensor is used to avoid unit fault or damage arising from over-high discharge temperature when
the system operates abnormally. When the discharge temperature sensor detects that the temperature exceeds
the safety range, the unit cannot operate and sends an alarm. The inlet pipe temperature sensor is one of
bases used by the system to judge frosting. The outlet pipe temperature sensor is one of important parameters
in control of the expansion valve.
Note: The inlet water temperature, outlet water temperature, pressure switch connection/disconnection
information, and wired controller information are transferred to the control mainboard. Based on the information,
the control mainboard controls actions of components such as the compressor, water pump, fan, and 4-way
valve.

(2) Defrosting exit criteria: The defrosting setting time comes or the pipe temperature reaches the
defrosting exit point.
