The present invention includes following a few external loop: coolant loop flow process, high-temperature-hot-water loop flow process, low-temperature water heating loop stream
Journey, directly-heated type hot water heating and chilled water circuit flow process.
Wherein, coolant loop flow process connects: compressor 1 (outlet) → warm condenser (the first condenser 3) → low temperature cold
Condenser (the second condenser 15) → directly-heated condenser 4 → coolant filter 13 → choke valve, 12 → vaporizer, 2 → compressor 1 (enters
Mouthful).High-temperature-hot-water loop flow process: (first is cold for high-temperature-hot-water pond 5 → high temperature circulation pump (first circulation pump 7) → warm condenser
Condenser 3) → high-temperature-hot-water pond 5.Low-temperature water heating loop flow process connects: Low Temperature Thermal pond 6 → cold cycle pump (the 3rd circulating pump
16) → low-temperature condenser (the second condenser 15) → Low Temperature Thermal pond 6.Directly-heated type hot water heating flow process: cold water inlet → enter water power
Dynamic valve 18 → directly-heated condenser 4 → Low Temperature Thermal pond 6 → high/low temperature separates the 5 → hot water outlet of connecting tube → high-temperature-hot-water pond.Freezing
Water loop flow process connects: freezing water inlet → vaporizer 2 → freezing water outlet.
The principle of each flow process and effect are as follows:
Coolant loop flow process: coolant enters high temperature condensation after becoming high temperature and high pressure gas after first passing through compressor compresses is carried out
Carry out second cooling heat release subsequently into low-temperature condenser after for the first time cooling heat release and be again introduced into directly-heated condenser carrying out the
Become Low temperature low pressure liquid, Low temperature low pressure liquid passes through choke valve current limliting after filter filtration, enters after three cooling heat releases
Entering evaporator evaporation heat absorption becomes low temperature low pressure gas, enters compressor and is compressed again, repeats above-mentioned flow process.This system with general
Logical heat production water system contrast coolant good cooling results, thermal discharge is big, and pressure is low, can reduce the load of compressor, extends compression
The service life of machine.
High-temperature-hot-water loop flow process: the hot water in high-temperature pool enters warm condenser heat absorption after the pressurization of high temperature circulation pump
High-temperature pool is returned after intensification.Hot water temperature in this flow process high-temperature-hot-water pond is stable, and cold water moisturizing temperature does not affect high-temperature water
Pond temperature.
Low-temperature water heating loop flow process connects: the hot water in low temperature pond enters low-temperature condenser after the pressurization of cold cycle pump
Heat absorption returns to low temperature pond after heating up.This flow process cools down for secondary refrigerant, good cooling results, and cold water moisturizing temperature does not affect hot water
Leaving water temperature.
Directly-heated type hot water heating flow process: after cold water water inlet initially enters the heat absorption intensification of directly-heated condenser, enter low temperature pond,
Being circulated after heating through low-temperature water heating loop becomes low-temperature water heating, then separates connecting tube by high/low temperature and flows into high-temperature-hot-water
Pond becomes high-temperature-hot-water after carrying out high-temperature-hot-water loop heating, finally export from high-temperature-hot-water pond and use.This flow process is cold for three times
But coolant, inlet water temperature is low, significantly cools down refrigerant temperature, is greatly improved the work efficiency of heat pump.
Refrigerating circuit flow process: water source or wind regime enter discharge or utilization after vaporizer absorbing and cooling temperature.
