Embodiment approach

[0022] 1. The so-called heat pump series connection means that the heat exchangers with built-in condensers are connected in series. The outlet of the first heat pump heat exchanger 22.1 is connected to the hot water tank... the inlet of the first heat exchanger is connected to the outlet of the second heat pump, and The heat exchanger of the last heat pump is connected to the heat pipe heat exchanger; the heat exchanger with built-in evaporator is also connected in series according to the above principle. 10.1. After connecting sequentially, the last heat pump is connected to the sewer. After the heat is reversed, the waste water reaches the sewer at only 2°C-7°C, and there is no waste of heat.

[0023] 2. Connect several small power heat pumps in series, so that the sum of the power of the small heat pumps is suitable for the amount of hot water produced. The main feature is that the heated water is heated step by step and no longer returns to the heat pump with a lower temp...

Abstract

It relates to a new multi thermal pump progressive heating method. On the one hand, it improves heating speed, and avoids heat short loss in the process of heating, using heat pump progressive heating method. It can be used in many fields, with low running cost, and better energy generation ability even than that of the solar energy.

Description

[0001] Field: [0002] The invention provides a heat pump heat collection method with higher efficiency, and a progressive heat recovery hot water boiler designed based on this principle. This zero-emission hot water boiler is used in the electronics industry and printing and dyeing industry where a large amount of hot waste water is discharged. , And baths, bathrooms have better economic benefits than coal boilers. technical background: [0003] With the shortage of petrochemical energy and the increasing emphasis on environmental protection requirements, air sources and waste water sources have been introduced one after another. However, in the heat pump heating method, two basic methods have been used: 1. The copper tube of the condenser is directly coiled in the water tank. 2. The water pump connects the hot water tank and the heat exchanger in series, and the water pump continuously sends the water in the water tank to the heating copper pipe of the heat exchanger to rece...
