Cryogenic refrigerants in the application of ground source heat pump

cryogenic swimming pool heat pump air as high grade ( Low grade) Heat sources for heating device. With air as the low grade heat source, can be inexhaustible, an inexhaustible, everywhere all have, free of charge. Air source heat pump installation of flexible, easy to use, the initial investment is relatively low, and is suitable for household installations, at present our country most of northern heating using high energy consumption of the boiler system, low boiler efficiency, emissions, caused great waste to the environment, the temperature of swimming pool heat pump, swimming pool constant temperature to the north of the country provides a better choice, also for future generations to leave more of the blue sky white clouds become a possibility. Working principle of the

swimming pool heat pump units by the evaporator, condenser, compressor, expansion valve four main parts form a closed system, which filled with the right amount of working medium. Basic principle of unit operation is based on reverse carnot cycle principle: liquid working substance in the first place in the evaporator absorbs heat from the air and steam evaporation formed ( Vaporization) , the latent heat of vaporization is reclaimed by heat, and then by the compressor compressed into high temperature and high pressure gas, into the condenser condensed into liquid ( Liquefaction) Send to absorb heat to need heating of the water, the liquid working medium after decompressional expansion of the expansion valve back on expansion valve, absorbing heat evaporation and complete a cycle, so on, constantly absorbing low temperature source of heat and heat output, pool water directly to the expected temperature. Compared with the normal heat pump in - 10 ℃ and a lower temperature, due to the evaporation temperature is too low, cause less evaporation, leading to low gas compressor back, which affects condensation heat release. Added a unicom cryogenic heat pump compressor injection increase enthalpy branch, when gas compressor back enough, injection increase enthalpy branch will give compressor to fill gas, condenser heat quantity will increase, so the extremely low temperatures can still normal heating.

unit in heat attenuation when environment temperature fell sharply as the minimal. Under the low temperature heating can effect comparing 50% higher than conventional units 80%, unit in the system of environmental temperature dropped sharply from time to time very little heat attenuation, fully guarantee the heating effect. In the standby mode, and cooling and heating are preferred for making in - living hot water 25 ℃ can be normal for making hot water, - 25 ℃ can effect comparing to 1. More than 8, and fully guarantee the low temperature condition for making hot water effect. Also can be used alone in cold area of north China.

low unit main components adopt international famous brand components.

low water and electricity separation, no waste gas, waste residue, safe and reliable, high efficiency and energy saving, green environmental protection.

low multiple protection, unibody design, unit operation is more stable.

low power automatic memory function, to start automatically after the unit operation, do not need specialist care.

in the ambient temperature is lower, the microcomputer automatic start function of frost.

low without special room, round-the-clock operation.

low engineering installation is simple, low operation and maintenance costs.
