Lack of air conditioning heating here to answer the original because it

It was winter, many of my friends are anxious waiting for the arrival of the winter heating season, but was unable to adapt to the temperature is too low in the House of friends are beginning to open up the air conditioner for home use, but use, many friends is always not enough response said, this strong zhinuan what reasons?

Today, the editors will give you simple explanation, in winter when using household air-conditioning appear strong enough heat.

1. improper use

Air conditioning in the long time without timely cleaning filters and internal air circulation close to a certain extent affect the air conditioning heating effect.

Evaporator, condenser and dirt is too thick, it will reduce the heat effect, causing the heating capacity, power consumption is increasing; heating temperature setting is too low.

While the air conditioning room door, wall holes are not blocked, or window open frequently, resulting in indoor thermal erosion can be unintentionally causing air conditioning not strong reason zhinuan.

II. environmental factors

-Warm and cold air conditioning, heat pumps-heat pump-assisted heater and electric-type three products that make heat equal conditions, the first two power consumption compared to the third half about small, taking into account the supply capacity and electricity costs, now family generally select the first two types of air conditioning (but it should be noted that their conditions of use, the first two only applies to-5 ° c above, clearly does not apply to the North).

Heat pump air conditioner, heating temperature is too low, reducing air conditioning energy efficiency ratio, in the colder winter heating effects of unsatisfactory, this is normal.

For no automatic defrosting of heat pump air conditioner that uses minimum ambient temperature is 5 ° c, zero is lower than the temperature would not heating or effect is very poor, this is because the external heat exchanger accumulate Frost blocked air flow, not from the outside world for the sake of inhaled heat; for automatic defrosting of heat pump air conditioner that uses minimum ambient temperature is-5 ° c lower than the temperature of the heating cannot be effective.

Third, the refrigeration system, control system malfunction

1. refrigerant.

Refrigerant leaks or insufficient reasons, then you can simple make a self-test to tell if the leakage of fluoride.

2. four-way valve with air.

Heat pump air conditioning through the four-way valve to toggle the State of refrigeration and heating.

If the four-way valves series gas, some of this should be involved in the heat of the refrigerant in the four-way valve Department directly by the compressor and the trachea to return to the return gas pipe, resulting in reduction of refrigerant heat exchangers, heat efficiency decreased and the resulting lack of heating.

3. check valves (valves) leakage.

When a one-way valve to leak gas, refrigeration system for high and low pressure drop, outdoor heat exchanger temperature to rise, the heat from the outside world gets reduced, resulting in insufficient heating.

When the air conditioning heating refrigeration normal, not failure, by detecting system run time pressure, will find the low pressure side pressure rise, high and low pressure drop.

4. the defrosting controller failure.

Heat pump air conditioning heating State of evaporator is located in the outdoor unit, for a hot punch cream defrosting devices heat pump air conditioning failure, if the temperature controller so that the air conditioning could not be promptly transferred to defrost the running state, the heat pump heating time evaporator effect of frost, air conditioning heating of heat exchange efficiency, resulting in insufficient heating, even outages.

This should focus on the observation of the existence of the following phenomena: defrost temperature sensor devices dislocation, contact adhesive edge or bad, fan impeller skidding or duct obstruction, solenoid valves or start relay failure.

5. auxiliary electric heating function fail.

Now heat pump-assisted air conditioning-heating-type generally used PTC auxiliary heating technology, PTC auxiliary heating technology can quickly in ultra-cold conditions, the effectiveness of strong, heating is safe and reliable, long term use.

If the electric auxiliary heating control circuit or electric auxiliary heating equipment failure, not working properly, at a relatively low environmental temperature, can result in lack of air-conditioning system for heat, even in poor conditions without heating when air conditioning.

For heat-pump-assisted air conditioning-heating-type, if the ambient temperature is high (more than 5 ° c) normal, and environmental heating temperature is relatively low (at 0 ° c) make heat low or no heating, electric auxiliary heating should be suspected control circuit or electric auxiliary heating equipment appears the breakdown, maintenance should be focused on checking the two parts.
