Problems solved by technology

These two water heaters directly use natural gas, coal gas or electricity to heat domestic water, which consumes a lot of energy and is expensive to use. 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 also some other invention patents and utility models, although they hope to use the condensation and heat release of the air conditioner to obtain hot water, but their 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, Instant hot water heater

Embodiment Construction

[0013] The basic structure of instant heat pump water heater system is as follows: figure 1 shown.

[0014] When domestic hot water at a certain temperature is required, open the valve 9 on the water inlet pipeline 7, close the valve 6 on the parallel short pipe 5, and start the compressor 1 of the heat pump water heater and the finned tube heat exchanger 4 at the same time. The fan and the refrigerant flow in the closed refrigerant pipeline in the order of 1-2-3-4-1, the finned tube heat exchanger 4 blows out cold air, and the outlet pipe 8 flows out hot water at a certain temperature. The temperature is related to the design size of the water-cooled heat exchanger. The water-cooled heat exchanger may be a shell-and-tube type, a casing type, or any other heat exchanger involving heat exchange between refrigerant and water.

[0015] When hot water is not needed, the compressor 1 of the heat pump water heater and the fan attached to the finned tube heat exchanger 4 are closed...

Abstract

The present invention relates to heat pump type air conditioner and water heater and is especially a kind of heat pump type water heater with the pow3r saving and safety features. The water heater isa refrigerating system comprising compressor, two heat exchangers, throttling mechanism, and corresponding pipeline, valves and control elements. Heat pump circulation is utilized to ehat instantly the water in the heat exchanger and the water heater has power consumption lower than that of electric water heater and gas water heater, and no hidden danger of electric shock and gas poisoning accident. Different setting makes the heat pump type water heater capable of providing also cold air, hot air or cold water.

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 kinds of water heaters directly use natural gas, coal gas or electricity to heat domestic water, which consumes a lot of energy, and the cost of use 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 also some other invention patents and utility models, although they hope to use the condensation and heat release of the air conditioner to obtain ho...
