Stainless Steel R410A Hot Water Air Source Heat Pump High Temperature 85 Degree

Principle of Stainless steel high temperature 85 degree R410A hot water air source heat pump

The basic operating principle of the cascaded high temperature air source heat pump unit is based on the reverse

Carnot cycle principle. The working fluid system is divided into a low temperature level circulation system and

a high temperature level circulation system. The low-pressure gas is compressed into a medium-temperature and

medium-pressure gas by the low-temperature stage compressor, and enters the intermediate heat exchanger to

condense into a liquid state to release heat. The liquid working medium is decompressed and expanded by the

expansion valve and then returns to the fin In the heat exchanger, the evaporation heat is absorbed again to

complete a low temperature cycle; at the same time, the liquid working medium of the high temperature machine

absorbs the heat transmitted by the low temperature stage in the intermediate heat exchanger and evaporates

into a medium temperature and low pressure gas, and the low pressure gas is compressed by the low pressure

stage compressor. The medium-temperature and medium-pressure gas is compressed into a high-temperature and

high-pressure gas by a high-temperature compressor, which is condensed into a liquid state in a heat exchanger

to release heat to produce high-temperature hot water. In the intermediate heat exchanger, the evaporation heat

is absorbed again to complete a low temperature cycle; through the reciprocating cycle, the effect of producing

high temperature hot water at a low temperature ambient temperature is achieved.

Strength of Stainless steel high temperature 85 degree R410A hot water air source heat pump

High outlet water tem

No need for electric heating in winter, saving energy and electricity. When the outdoor ambient temperature is as low as -30°C, the

outlet water temperature of 85°C can still be maintained.

M o d u l a r d e s i g n , m e e t v a r i o u s n e e d s

With modular design, each system can realize the free combination of multiple units, which can easily meet various building needs. If one unit in the module combination fails,

the other units can operate normally, the backup operation performance is superior, and the use is more assured

S t r o n g a d a p t a b i l i t y t o e n v i r o n m e n t a n d h e a t l o a d

The unit can run stably at an ambient temperature of -35~50, and the temperature of hot water can reach 90, which is

suitable for various heating demand applications.

I n t e l l i g e n t n o n - s e n s i n g d e f r o s t c o n t i n u o u s h e a t i ng

Intelligent rapid non-sensing defrosting technology, greatly reducing the number of defrosting and defrosting time. The

defrosting interval is extended to 7 hours at the longest, and the heating continues without feeling hot and cold!

S u p e r l o w t e m p e r a t u r e h e a t i n g p e r f o r m a n c e

Working principle: The two-stage cascade coupling system is divided into a low temperature stage circulation system and a high

temperature stage circulation system, which reduces the compression ratio of the unit operation and improves the low temperature

operation efficiency of the unit.

I n d o o r a n d o u t d o o r l i n k a g e c o n t r o l , i n t e l l i g e n t o n e - h a n d c o n t r o l

The temperature controller of indoor fan coil unit and floor heating is

controlled by linkage with the outdoor main unit. When any terminal

controller is turned on, the main unit is automatically turned on. When

all terminal controls are turned off, the main unit is automatically

turned off, and the system application is more energy-saving.

M u l t i p l e p r o t e c t i o n s e n s u r e t h e s a f e o p e r a t i o n o f t h e s y s t e m

The host has 11 equipment self-checking protections, including compressor exhaust temperature protection, system high and low pressure protection,

double antifreeze and heat protection, fan motor overload protection, frequent start limit protection, and power-off memory recovery function to protect the

unit and use it safely.
