Embodiment Construction

[0012] figure 1 It is a structural diagram of an instant heat pump water heater.

[0013] 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 leaves hot water at a certain temperature, and the hot water The temperature is related to the design size of the water-cooled heat exchanger. The water-cooled heat exchanger can be a shell-and-tube type, a sleeve-and-tube type, or other forms of heat exchangers involving heat exchange between refrigerant and water.

[0014] When hot water is not needed, the compressor 1 of the heat pump water heater and the fan attached to the finned tube exchanger 4 are...

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...
