Embodiment Construction

[0025] The multi-stage series waterway primary heating heat pump water heater of the present invention is composed of a plurality of relatively independent heat pump systems and multi-stage series water systems, adding condensed liquid refrigerant to the heat pump system of the final stage (i.e. the highest stage) for heat recovery device. Each of the plurality of heat pump systems therein is a complete circuit including a compressor, a condenser (water heat exchanger), a throttling device and an evaporator.

[0026] Among them: the water inlet of the hot water unit is connected to the water inlet of the refrigerant heat recovery device, the water outlet of the refrigerant heat recovery device is connected to the water inlet of the condenser of the first-stage heat pump system, and the condenser of the first-stage heat pump system The water outlet is connected to the condenser water inlet of the second heat pump system, and so on until the condenser water outlet of the final h...

Abstract

The present invention relates to a multi-level serial water channel one-time heating type heat pump water heater, which consists of at least two relatively independent heat pump system and multi-stage serial water system, a condensate liquid refrigerant heat recoverer is added to the ultimate-level(the most senior) heat pump system, wherein, the water inlet of a water heater group is connected to the water inlet of the refrigerant heat recoverer, the water outlet of the refrigerant heat recoverer is connected to a condenser water inlet of the first level heat pump system, a condenser water outlet of the first level heat pump system is connected to a condenser water outlet of a second level heat pump system, by analogy, till to the condenser water outlet of the ultimate-level heat pump system. The fluorine side inlet of the refrigerant heat recoverer is connected into the condenser drained liquid refrigerant of the ultimate-level heat pump system, and the fluorine side outlet of the refrigerant heat recoverer is connected to a throttling device inlet of the ultimate-level heat pump system.

Description

technical field [0001] The invention relates to a heat pump water heater in an air-conditioning unit, in particular to a heat pump water heater of a multi-stage serial waterway heating type. Background technique [0002] In the whole process of heating domestic hot water, in order to make the compressor of the heat pump water heater work at the ideal condensing pressure as much as possible, maximize the heating energy efficiency ratio, make the operation of the unit more stable and reliable, and work more efficiently; At the same time, the structure of the hot water system is as simple as possible, the input cost is low, and the occupied space is small. The existing heat pump water heater generally adopts the following two heating forms: [0003] 1) Hydronic heating type (see figure 1 ), that is, the side-inlet water flows through the heat pump water heater for many times through the water pump, and is gradually heated to the set end temperature of the water heater. Its wo...
