Abstract

The utility model discloses a heat pipe and heat pump combined system. The heat pipe and heat pump combined system combines traditional heat pump compression refrigeration technology and heat pipe technology. The heat pipe and heat pump combined system comprises a condenser, an evaporimeter, a compressor, a throttle valve, a liquid storage pot, a circulating pump, a liquid-returning device, a magnetic valve, four one-way valves and a circuit control component.

Description

A kind of heat pipe hot pump hybrid system

Technical field

The utility model belongs to refrigeration and heat transfer technology field, relates to a kind of heat pipe hot pump hybrid system of conducting heat and freezing that hot-pipe system and heat pump are compounded to form mutually.

Background technology

The air-conditioning system chief component that is used at present the regulation and control environment temperature is indoor heat exchanger and outdoor heat exchanger, this air-conditioning system can realize by the highly energy-consuming of compressor in the indoor heat exchanger temperature adjusting to condensing agent, thereby indirectly change indoor environment temperature, this air-conditioning system is not accomplished good energy savings, when outdoor temperature is lower than indoor temperature, because (extraneous dust concentration is large for certain reason, air pollution etc.) can not carry out direct cross-ventilation cooling by window opened via, the compressor of at this moment also having to open highly energy-consuming carries out adjustment, this phenomenon is at high temperature dustproof environment (machine room, the special high temperature occasions such as electricity chamber) performance is obvious especially, because the use occasion heat dissipation equipment is concentrated, heat dissipation capacity is large, space temperature is high, quick heating, prevent dust and require high characteristic, so that use traditional air-conditioning to be difficult to conserve energy here, start the heat pump cooling even also have to when outdoor temperature is more much lower than indoor temperature, and now relative energy-saving a kind of introduces the mode that all-fresh air lowers the temperature a lot of areas is inapplicable at home, a large amount of outdoor dust and humid air can be brought into indoorly, the safety that affects indoor equipment is normally moved.

The form of the another kind of wind that adopts---wind heat exchanger can be avoided introducing outdoor dust and humid air indoor, but need to offer larger ventilation hole at safeguard structures such as equipment room, machine room enclosure walls, not only destroy the stability of body of wall, also have stolen potential safety hazard.

Some season throughout the year, such as winter and spring and autumn, lower and can not carry out in the situation of indoor-outdoor air convection current than the design temperature in indoor heat release zone in outdoor temperature, the compressor that does not also have a kind of system can need not open in this case highly energy-consuming just can carry out indoor temperature control, even in this case, the compressor that existing air-conditioning system must start highly energy-consuming particularly those caloric values is concentrated temperature is controlled to environment in the demanding workplace of cleannes, this scheme that still adopts heat pump to lower the temperature to cool off is not energy-conservation, thereby the unnecessary waste that causes electric energy, operation costs are high.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming that prior art exists, for solving the large problem of energy consumption that exists in the heat pump, and provide a kind of simple in structure, implement easily, the heat pipe hot pump hybrid system of energy-saving and emission-reduction, when can indoor required design temperature being lower than outdoor temperature, use heat pump cycle to freeze, when indoor required design temperature is higher than outdoor temperature, heat-pipe apparatus is started working, can safety, reliably, stable, the energy-conservation automatic running refrigerating circulatory system, this heat pipe hot pump hybrid system not only makes Heat Pump control device for cooling merge, gas-liquid separation and circulation some drawbacks on unstable have improved the refrigeration heat transfer efficiency when also having solved existing heat pump refrigerating device refrigeration.
