How to Conduct Wotech Heat Pump Leakage Check?

How to Conduct Wotech Heat Pump Leakage Check?

There are three leakage checks during heat pump production in Wotech. 

After the building of refrigeration system, nitrogen is charged into the copper pipes. Soap-suds is brushed on the surface of copper pipes especially the welding point. If leakage exist, there are bubbles popping out.

The second leakage check is conducted after the charging of refrigerant. The welding points are checked with the sniffer. Leakage detector can recognize the leakage of 2g/year. 

The third leakage check is after the performance testing. Refrigeration runs through the whole system. Leakage is easier to be found. 

For more about our strict quality control system pls visit www.wotech.cn.

How to Conduct Heat Pump Components Check?

PCB boards are tested under big range of electricity from 176V to 264V. The poor-quality ones are sent back to our suppliers.

Pressure gauges are charged into nitrogen for 72 hours with note marking status. 

Titanium heat exchangers are charged with 4 bar water pressure. And the titanium coils are kept with nitrogen for 48 hours.

Wotech has strict quality control on each components. For more about us pls visithttp://www.wotech.cn.

Wotech Heat Pump Attended the Israel Union Business Conference

Wotech Heat Pump Attended the Israel Union Business Conference

Miss Stella Yau, the representative of Wotech Heat Pump Group, was invited to attend the Israel Union Business Conference on May 20th, 2014. The bilateral cooperation was fully discussed during the meeting, with the Vice President and other senior managers.

Israel is located in a complicated geothermal situation——most of its territory is covered by desert. Its lack of energy resources is hardly complemented from Arabic countries. Facing this, Israel government ascribe great importance on renewable energy, hoping that some powerful enterprise for renewable energy would bring them development.

Pushed by the trend of low-carbon economy, air-source products are popular with its pollution-free and renewable quality. Wotech, as a new energy enterprise that focuses on heat pump manufacturing since 2005, it pushes its sales volume exceeded 300 million RMB within 10 years. Its power is extended to Europe, North and South America, Middle East, Southeast Asia, etc. and it established R&D institutions in Britain, South Africa, Indonesia, America and Chile.

Mr. ArieZief, the Vice President of Israel Union Business Conference, presented its approval in cooperation with Wotech. He added that both sides would explore the pattern of long-term cooperation, pushing the progress of new energy technology exchange between Israel and Wotech.

Wotech strives to cooperate with potential enterprises and institutes from all over the world. For more please kindly visit www.wotech.cn.

Pool Heat Pump

Pool Heat Pump

Heat pumps make use of free heat from the sun by collecting and absorbing energy from the outside air.

• This device contains a ventilator which draws the outside air in and makes it flow over the surface of

the EVAPORATOR (energy collector). The liquid coolant in the EVAPORATOR pipeline absorbs the heat

from the outside air and the coolant vaporises.

• The warm gas in the pipeline passes through the COMPRESSOR which gathers the heat and increases

the temperature to generate very hot gas which then passes to the CONDENSER (water heat exchanger).

This is where the heat exchange occurs – the hot gas transfers heat to the colder water from the pool which

is circulating through the coil.

• The pool water is heated and the hot gas is cooled when passing through the CONDENSER pipeline

– it regains its liquid form and, after the passage through the CAPILLARY TUBE, the whole process

recommences.

• The current technology used in the heat pump allows efficient use even at an outside air temperature of 7 to 10 ºC.

For tropical and subtropical climates, this means that 26 to 32 ºC may be maintained in the pool under almost any

conditions all year round. In northern countries, the heat pump considerably extends the swimming season.

We Wotech, one of the best heat pump manufacturer in China, we produce high quality heat pumps, especially pool heat pump, domestic heat pump, monobloc heat pump so on. To know more us, please visits our website at www.wotech.cn

An Important Part in Heat Pump

Be regarded as the heart of a compressor refrigeration system , the best
performance characteristics of the compressor terminology as ” vapor pump .”
Compressor actual responsibilities is to enhance the pressure to suction pressure
state referred to the exhaust pressure.
The compression ratio is a technique which means that the differential pressure
method in the sense of absolute pressure divided by the high-pressure side to the
low pressure side of the absolute pressure . Calculating the compression ratio must
be absolute pressure values. In order to avoid a negative value of the compression
ratio , calculated pressure ratio must be used when absolute pressure , not gauge
pressure . Absolute pressure values ​​to calculate the compression ratio is positive ,
this makes sense .
Used in refrigeration and air conditioning industry has five major types of
compressors : reciprocating, screw , rotary , scroll , and centrifugal, reciprocating,
which are small and medium-sized commercial refrigeration systems use up to a
compressor . Screw compressors mainly for large commercial and industrial systems.
Rotary compressors , scroll compressors and reciprocating compressors mainly for
household and small-capacity commercial air conditioning equipment , centrifugal
compressors are widely used in air-conditioning systems of large buildings.

Reciprocating compressors are generally based on various forms of the compressor 

housing and a drive mechanism set way classification. According to the form of the
housing has an open and closed half- hermetic compressors . Enclosed is the entire
compressor are disposed within a housing .
