High-temperature multifunctional heat pump technology products realize green energy saving and emission reduction

Artificial cooling and heating technology (cooling and heating) has become an indispensable and important part of human civilization. It has been more than a hundred years since the first refrigerator in the world came out. The development of refrigeration technology has promoted the development of human civilization. And heating technology has created a more comfortable environment for human life. The application of cooling and heating technology has become an indispensable and important condition for the development of today's civilized society.

Refrigeration and heating (heat pump) are processes and measures for artificial cooling or heating, that is, using a certain device system to artificially combine (inherent or existing) in a space (or certain substances) ) The heat is quickly absorbed and then transferred and released to another space (or another part). The temperature in the space (or object) that has absorbed the heat decreases (relatively), and the temperature in the space (or material) that has received more heat increases. .

For a long time, due to various reasons and traditional scientific research models, the development and application of refrigeration and heating technology has not reached the required level of development, especially large air-conditioning devices (refrigeration units) can only be used for cooling and cooling. Only some low-power air-cooled air conditioners have dual temperature (heat pump) function, but the heating and heating effect is poor, especially when it is used for heating and heating in cold winter, the effect is worse, and most of them need additional electric heating to supplement heating; nearby The so-called water-source heat pump and ground-source heat pump air-conditioning devices, which have been developed in the past few years, have two different configuration modes. One is that the larger heating and cooling unit uses a simple external process conversion to make the traditional refrigeration unit (chiller) condense. The hot water produced in the evaporator and the low-temperature cold water produced in the evaporator are output respectively through the conversion of the process switching valve; the other is a small unit, which uses the conversion function of the four-way reversing valve to realize the cooling and heating conversion of the heat pump unit to achieve the For the purpose of cooling or heating, it is difficult to achieve the ideal multi-purpose dual-temperature effect and energy-saving effect.

So far, large-scale air-cooled heat pump air conditioners have not yet achieved true full heat pump heating and cooling. The heating and heating effect of heat pump units is poor, and most of them need to directly use electric heating auxiliary heating. The heating and heating network is difficult to achieve Effective defrosting in time, especially for large heat pump heating and cooling air-conditioning devices, it is more difficult to achieve full heat pump direct heating and heating. Some of them can provide a certain amount of heating heat source, but most of them also add a large amount of electric heating and electric heating energy consumption. Big and high cost. The secondary condensing high temperature multifunctional heat pump makes full use of the general principle of artificial refrigeration and comprehensively adopts the different effect processes of various artificial refrigeration systems, so that the refrigeration (heat pump) unit realizes the working conditions of high temperature heating and multi-purpose. Operation, can realize the function of automatic control conversion, can make the state of evaporation and condensation (cooling and heating) to realize uninterrupted heating and multi-functional utilization, and can be used for cooling and cooling, heating and heating and providing domestic hot water at the same time.

As we all know, the heat pump device is a kind of energy conversion device with relatively large input and output. The energy efficiency ratio of the traditional refrigeration (heat pump) device can reach more than 1:2, 8. The refrigeration (heat pump) device developed by the reasonable configuration of new technology The energy efficiency ratio can reach more than 1:5, which is the energy efficiency that cannot be compared and realized by all electrical heating and cooling (or electric heating) equipment at present, and the heat pump device has the characteristics of simple structure, stable performance, easy operation, safety and reliability, etc., using heat pump device Supporting cooling, cooling and heating for all types of buildings, with low investment, low cost, no pollution, and good management. It is a centralized cooling (heating) device that realizes the ideal of low-cost, high-efficiency and risk-free operation, and also changes modern civilization. It is an indispensable and important condition for the appearance of the city and creating a more comfortable living environment for human beings. The secondary condensing high-temperature multifunctional heat pump cooling and heating technology is another innovative breakthrough and development of artificial refrigeration technology. It will promote the vigorous development and widespread application of heat pump cooling and heating air-conditioning, and will also curb the depletion of humans. The transitional demand for energy has played a major role, while avoiding serious pollution caused by the increasing use of coal-fired boilers for heating, and is an important part of ensuring the realization of the 65% building energy saving plan.
