3 Definition
For the purpose of this Standard, the following definitions given in JB/T 7249-1994 shall
apply.
3.1
Ducted air-conditioning (heat pump) units
Equipment that provides centralized processed air to confined space, room or area through
ducts. It mainly includes refrigeration system, air circulation and purification device and
also including heating equipment, humidification equipment and ventilation equipment. it
is hereinafter referred to as air conditioner.
3.2
Auxiliary electric heater for heating
Electric heater that is used for heating with heat pump (including post-installation electric
heaters).
3.3
Heat water coil
Equipment of which the air, guided by fan, flows through and gets heated by the coil-pipe
in which the external heat-water flows through.
3.4
Heating equipment with electric beater
5.1.7 The action of magnetic exchange valves of heat pump air conditioner shall be
sensitive and reliable, and be able to ensure the normal operation of air conditioners.
5.1.8 The thermal-protective coating of air conditioners shall have good heat insulation
performance, and shall be non-toxic, odor-free and has self-extinguishing function. It shall
have no condensation phenomena on the surface in normal operation.
5.1.9 The parts of air conditioner refrigerating system shall be able to ensure the normal
operation of the whole unit without degradation under the affection of refrigerants,
lubricants and their mixture.
5.1.10 The compressor of air conditioners shall be equipped with measures against
vibration or be equipped with anti-vibration spring washers when being fixed.
5.1.11 Salt-frog resistance of electroplated parts
After the test to electroplated parts is done according to the method in 7.3.22, each rust
spot in the electroplated layer shall not exceed 1 mm2; the electroplated layer of each 100
cm2 shall have at most 2 rust spot and rust stain; when the area is less than 100 cm2, there
shall not be rust spot and rust stain.
5.1.12 Coating adhesion of painted parts
After the test is done according to the method in 7.3.23, the number of shedding of paint
film shall not exceed 15% of the total number.
5.1.13 All parts and materials of air conditioners shall comply with relevant provisions of
their standards respectively, meet the requirements of use performance and ensure safety.
5.1.14 The electrical systems of air conditioners shall be equipped with overload protection,
vacant phase protection (three-phase power) to their motors. When the nominal
refrigerating capacity of air conditioners is larger than 4500 W, the refrigerating system
shall be equipped with necessary protection functions or devices for high voltage, low
voltage and others. If necessary, it shall also has reverse phase protection function or
devices.
5.1.15 The selection of electrical components of air conditioners and installation and wiring
of electric appliances shall comply with requirements of GB 4706.32 -1996 and GB/T
5226.1-1996.
5.2 Performance requirements
5.2.1 Sealing performance of refrigerating system
There shall not be refrigerant leak in each part of the refrigerating system in the test
conducted according to the method in 7.3.1.
In the test conducted according to the method in 7.3.10, the water resistance of heat water
coil shall not be more than 110% of its nominal water resistance.
5.2.11 Maximum load refrigeration operation
a) In the test conducted according to the method in 7.3.11, each part of air conditioners
shall not be damaged and shall be able to operate normally;
b) Air conditioners shall be able to operate normally during the first hour of continuous
operation;
c) Continue to operate air conditioners for 1 hour after 3 minutes of halt; however, it
allows the overload protector to trip off within the first 5 minutes of operation and do
not allow it to trip off after that; when the overload protector does not reset within the
first 5 minutes of operation AND it resets within the period not exceeding 30 minutes
after halt, then it shall continue to operate the air conditioner for 1 h.
d) For manual reset overload protectors, if they trip off within the first 5 minutes, then it
shall be reset forcibly after 10 times when they trip off, they shall be able to operate
for further 1 hour continuously.
