Lemon heat pumps enjoy over 20 years experience, leader for
editting heat pumps standard,
A variety of hot water control systems of composite energy pressure
bearing modules are disclosed, including air source heat pump water
heater, solar energy collector, electric heating pipe, pressure
module heating water tank, first pressure module heat storage tank
and second pressure module heat storage tank. The air source heat
pump water heater and pressure module heating water tank are
connected with circulating pipe and return pipe, and the middle
part of the circulating pipe Air source circulating water pump is
installed. By installing the air source heat pump water heater,
electric heating pipe and solar collector in the system, the air
energy, solar energy and electric energy can be combined into a
heating system. If there is more hot water demand, a large amount
of hot water can be produced by using air energy, solar energy and
electric energy together through the control system. Through this
system, not only can a large amount of hot water be produced, but
also has a good energy saving effect. It has a high intelligence
degree, and can adapt to different use demands and various rings
Also intent a valve patent.The invention discloses a check valve
and a compressor system with a check valve, belonging to the
technical field of compressors. A one-way valve comprises a valve
hole I (131), an oil stop steel ball (132), an oil stop spring
(133) and a valve hole II (134). One end of the oil stop spring
(133) fixes the inner side of the valve hole II (134), and the
other end pushes the oil stop steel ball (132) against the inner
side of the valve hole I (131). A compressor system of the check
valve comprises an evaporator (2), a condenser (3), a throttle
valve (4) and a pipe (5), which is characterized in that it also
comprises a compressor module (1), and the compressor module (1)
comprises a compressor (11), an exhaust port (12), an exhaust oil
check valve (13), an intake port (14) and an intake oil check valve
(15). It can prevent the compressor oil flow to the unit pipeline,
so that the compressor system can work safely and stably.
