Problems solved by technology

Because of these restrictions, ordinary water heaters can only be used in areas south of the Yangtze River, and in East China, the efficiency of water heaters is relatively poor in winter, and the energy efficiency cannot reach 2.0, and it becomes a big power consumer in winter. Bring a heavy load to the already tense energy

Abstract

The invention relates to an ultralow temperature water heater capable of being used at 25 DEG C below zero, which comprises a first system, a second system and a fluorine-fluorine plate-type heat exchanger, wherein the fluorine-fluorine plate-type heat exchanger is connected between the first system and the second system; the second system comprises a second compressor, a second condenser, a second throttle valve and a second flow separator; the fluorine-fluorine plate-type heat exchanger is respectively connected between a first condenser and a reservoir, and between the second throttle valve and a second flow separator; the second flow separator passes through the second compressor and is connected with the second throttle valve via the second condenser. The invention has the beneficial effects that the set of the invention can be used in the area north of the Changjiang River, improves the energy efficiency ratio of the water heater at a low temperature, and saves energy, thereby satisfying the current national energy conservation and emission reduction requirements.

Description

technical field [0001] The invention relates to a low-temperature water heater, in particular to the structure of the low-temperature water heater. Background technique [0002] Depend on figure 1 It can be seen that a common water heater system is mainly composed of four parts: an evaporator 1, a compressor 2, a condenser 3, and a throttle valve 4, and also includes: a liquid receiver 5 connected between the throttle valve and the condenser, a compressor and the airflow separator 6 between the evaporator, the four-way valve 7 respectively connected between the compressor and the condenser and the airflow separator evaporator, and the pipelines connecting the above-mentioned components. [0003] When the system is a single system, when the temperature is as low as -10°C, the evaporation capacity of the system decreases, causing the discharge pressure of the compressor to increase, the suction pressure to decrease, and the compression ratio to increase. At this time, the spe...
