Description
Technical Field
The invention belongs to the field of air conditioners, and particularly relates to an air conditioner circulating heating system.
Background
The outdoor unit of the central air conditioner frosts in the heat exchange process in winter, the heating is automatically stopped in the defrosting process, so that the temperature of an air outlet of the air conditioner of an office building is reduced, and the indoor temperature cannot be maintained. The principle of air conditioner heating is that heat absorbed by the outdoor unit is transferred to the indoor unit and released, and because the heat absorbed by the outdoor unit is rapidly taken away by the air conditioner, the outdoor unit is quenched, and moisture in the air can be condensed into frost. The heating of the air conditioner is affected after the outdoor unit frosts, and the defrosting function of the air conditioner can automatically defrost. The lower the outdoor air temperature is in winter, the higher the relative humidity is, the frequent defrosting of the air conditioner is, and the heating efficiency is influenced. When the outdoor temperature is lower than 5 ℃, the evaporation temperature of the outdoor heat exchanger is below 0 ℃, moisture in the air can frost on the surface of the outdoor condensing plate, and the frost thickness can be increased along with the increase of the operation time, so that the heat exchange performance of the heat exchanger is reduced, the heating effect is reduced, the air humidity in the Hubei area is high, and the frost formation rate is increased. In severe cases, the central air conditioning screw compressor continues to be in the defrost mode for a long time and stops heating.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned technique not enough, provide an air conditioner heating system to solve because winter outdoor temperature is low excessively, the off-premises station frosts, leads to the problem that heat exchanger heat transfer performance descends.
In order to achieve the technical purpose, the technical scheme of the utility model provides an air conditioner circulation heating system, including delivery pipe and wet return, be provided with air conditioner intake door and air conditioner return door on delivery pipe and the wet return respectively, one side of air conditioner inlet tube still is connected with a bypass, the bypass with the air conditioner intake door is parallelly connected, be provided with heat exchanger intake door, heat exchanger and heat exchanger return door on the bypass, heat exchanger intake door and heat exchanger return door set up respectively the both sides of heat exchanger, heat exchanger intake door, air conditioner intake door and heat exchanger return door constitute a return circuit.
Furthermore, the water supply pipe and the water return pipe are both connected with water drain pipes, and the water supply pipe and the water return pipe are respectively communicated with the heating and ventilating pit through the two water drain pipes.
Further, the heat exchanger is a steam heat source for power plant production.
Compared with the prior art, the beneficial effects of the utility model include: the utility model provides an air conditioner circulation heating system increases a little bypass and causes the heat exchanger on air conditioning system's former inlet channel, and the air conditioner water heating of original air conditioner closed circulation is through the heat exchanger to guarantee that the outer machine of air conditioner continues to heat as the temperature of the heat medium transport medium of each air conditioner end of office building at the defrosting in-process. When the heat exchanger has high efficiency of heating the air conditioning water, the screw compressor can quit operation, so that the energy consumption of the whole air conditioning system is reduced, and the cost is reduced. The heat exchanger adopts the steam heat source for the production of the existing power plant, so that the resources can be fully utilized, and the cost is reduced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
When heating in order to solve current central air conditioning system winter, because outdoor temperature is low excessively, the off-premises station frosts, influences the problem of heating the function, the embodiment of the utility model provides an air conditioner circulation heating system. See figure 1 in particular.
As shown in fig. 1, an air conditioner circulation heating system comprises a water supply pipe and a water return pipe, wherein an air conditioner water inlet door 4 and an air conditioner water return door 5 are respectively arranged on the water supply pipe and the water return pipe, one side of the air conditioner water inlet pipe is further connected with a bypass, the bypass is connected with the air conditioner water inlet door 4 in parallel, a heat exchanger water inlet door 2, a heat exchanger 1 and a heat exchanger water return door 3 are arranged on the bypass, the heat exchanger water inlet door 2 and the heat exchanger water return door 3 are respectively arranged on two sides of the heat exchanger 1, and the heat exchanger 1, the heat exchanger water inlet door 2, the air conditioner water inlet door 4 and the heat exchanger water return door 3 form. And the water supply pipe and the water return pipe are both connected with water drain pipes, and the water supply pipe and the water return pipe are respectively communicated with the heating ventilation pit through the two water drain pipes.
The utility model provides an air conditioner circulation heating system increases a little bypass and causes heat exchanger 1 on air conditioning system's former inlet channel, through heat exchanger 1 with the circulating air conditioner water heating of original air conditioner closed to guarantee that the outer machine of air conditioner continues to heat as the temperature of the heat medium transport medium of each air conditioner end of office building at the defrosting in-process.
