Abstract
The utility model discloses an elevator machine room refrigerating circuit, this control circuit include air switch K1K 2, ac contactor CT, mechanical type air-cooler FAN, temperature controller TCU. The automatic temperature control system is characterized in that the temperature controller TCU controls the AC contactor CT to be connected with or disconnected with a power supply loop of the mechanical air cooler FAN, so that the automatic temperature control of the elevator machine room is realized. The method realizes automatic control, saves manpower, avoids uncertainty of manual operation, and is more energy-saving and economical in operation.
Description
Technical Field
The utility model relates to a space refrigeration technology, especially an elevator machine room refrigerating circuit.
Background
According to the standard regulation of GB/T10058-2009 elevator technical conditions, the air temperature in the elevator machine room should be kept between +5 ℃ and +40 ℃, therefore, the common cooling measure of the elevator machine room is to arrange a split air conditioner. When the cooling mode of the air conditioner is adopted, the air conditioner needs to be manually operated by property personnel to the site when being opened and closed, and for a large-scale residential area, the elevator machine rooms of each high-rise residence are far away, the number of the elevator machine rooms is large, the operation and maintenance are inconvenient, the operation is not energy-saving, and the economy is not realized.
The existing air conditioner temperature control circuit uses an intelligent air cooler, and in the practical application process, the temperature of the air cooler can be controlled according to the temperature change only when the air cooler is in a standby state, so that the air conditioner is not energy-saving in operation.
Disclosure of Invention
To the problem that exists among the prior art, the utility model provides a break-make of control ac contactor CT controls opening of mechanical type air-cooler FAN and stops, realizes that the temperature that makes elevator machine room reaches default, elevator machine room refrigerating circuit of economic energy-conserving automatically.
The purpose of the utility model is realized through the following technical scheme.
The cooling circuit of the elevator machine room comprises an air switch K1/K2, an alternating current contactor CT, a mechanical air cooler FAN and a temperature controller TCU, wherein the air switch K1/K2 and the alternating current contactor CT are arranged in an elevator distribution box AP, the temperature controller TCU controls the alternating current contactor CT to be connected with or disconnected with a power supply loop of the mechanical air cooler FAN, and an air outlet of the mechanical air cooler FAN is located in the elevator machine room.
Power is supplied to the temperature controller TCU through an air switch K1; air switch K2 provides power to mechanical air cooler FAN through ac contactor CT, and the normally open contact of ac contactor CT is controlled by the output of temperature controller TCU.
Compared with the prior art, the utility model has the advantages of: the utility model discloses a temperature is preset to temperature controller TCU to opening of mechanical type air-cooler FAN is controlled to the break-make of control ac contactor CT stops, realizes that the temperature that makes elevator computer lab reaches the default automatically. The utility model discloses an automatic control has saved the manpower, has avoided the uncertainty of manual operation, and the application of mechanical type air-cooler need not the standby, moves more energy-conservation, economy.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: AP: elevator block terminal, K1, K2: air switch, CT: ac contactor, CTU: temperature controller, FAN: mechanical type air-cooler.
Detailed Description
The invention is described in detail below with reference to the drawings and specific examples.
As shown in fig. 1, the elevator machine room refrigeration circuit comprises an air switch K1/K2, an alternating current contactor CT, a mechanical air cooler FAN and a temperature controller TCU, wherein the air switch K1/K2 and the alternating current contactor CT are installed in an elevator distribution box AP, the temperature controller TCU controls the alternating current contactor CT to be connected with or disconnected from a power supply loop of the mechanical air cooler FAN, and an air outlet of the mechanical air cooler FAN is located in an elevator machine room. The temperature of the elevator machine room can be automatically controlled.
Power is supplied to the temperature controller TCU through an air switch K1; air switch K2 provides power to mechanical air cooler FAN through ac contactor CT, and the normally open contact of ac contactor CT is controlled by the output of temperature controller TCU.
When elevator machine room temperature was less than temperature controller TCU's settlement temperature, temperature controller TCU no signal output, and AC contactor CT's normally open contact is in the off-state, mechanical type air-cooler FAN power disconnection, and mechanical type air-cooler FAN is out of work.
When the temperature of the elevator machine room is higher than the set temperature of the temperature controller TCU, the temperature controller TCU outputs a signal, the normally open contact of the AC contactor CT is attracted, the mechanical air cooler FAN is powered on, and the mechanical air cooler FAN operates to cool the elevator machine room.
The used component of this circuit, electrical apparatus are the design product, can directly purchase on the market, through simply connect can, have better practicality.
