Instant-heating heat-pump water heater

Abstract

The invention discloses an instant-heating heat-pump water heater consisting of a compressor, two heat exchangers, a throttle mechanism and the other corresponding pipelines, valves and control elements, wherein the heat exchanger for heating domestic water is the water-cooled heat exchanger; the other heat exchanger is the finned-tube heat exchanger; the throttle mechanism in the system is connected with a short pipe having no throttling function in parallel; the valves on the short pipe can control the pipelines to open or close. When the compressor of the heat-pump water heater stops, valves on the short pipe open, and the short pipe connected with the throttle mechanism in parallel opens. Refrigerants in the instant-heating heat-pump water heater absorb the heat converted by the electricity and environmental heat to heat the water flowing through the heat exchangers; and the power consumption is lower than that of the electric water heater with the same water yield. Compared with the general electric water heater and the general gas water heater, the heat-pump water heater eliminates the hidden dangers of the electric shock accident and the gas poisoning accident. Therefore, the instant-heating heat-pump water heater is energy-saving and secure.

Description

technical field [0001] The patent of the present invention relates to a heat pump air conditioner and water heater, especially a heat pump water heater capable of instantly providing hot water for bathing. Background technique [0002] Existing water heater mainly comprises gas water heater and electric water heater two kinds. These two water heaters directly use natural gas, coal gas or electricity to heat domestic water. The small size has a lot of energy, and the use cost is high. There are also hidden dangers of safety accidents such as gas poisoning or electric shock. The heat pump type safety water heater whose patent No. is 99113401.x hopes to utilize the heat pump to reclaim various available heat sources, so as to achieve the purpose of safety and energy saving, but the structure is very complicated. There are other invention patents and inventions that hope to use the condensation and heat release of the air conditioner to obtain hot water, but the starting po...

Problems solved by technology

These two types of water heaters directly use natural gas, coal gas or electricity to heat domestic water. The small size has high energy and high usage costs, and there are also hidden dangers of safety accidents such as gas poisoning or electric shock.

The heat pump safety water heater with patent No. 99113401.x hopes to use the heat pump to recycle various available heat sources to achieve the purpose of safety and energy saving, but the structure is very complicated

There are other invention patents and inventions that hope to use the condensation and heat release of the air conditioner to obtain hot water, but the starting point is to treat the heating of domestic water as an additional function of the air conditioner, instead of directly using the heat pump principle to create a simple and practical water supply that can be provided instantaneously. hot water heater
